Colour-coded bags: a small idea that saves real site time

Site delays over the wrong bolt turning up are more common than they should be, and Andrews Fasteners set out to fix that over a century into the trade. We originated the colour coded bag system now used across the industry, and it still solves a genuine problem.

Here's how it works. Red means M12, blue is M16, yellow is M20, green is M24, black is M30. One glance tells site teams what's in the bag, no measuring, no guessing.

The bolts themselves carry diameter and length stamped directly on the head, so the right connection gets the right fastener even after the bag's been opened. Labels are weatherproof, non-tearable, and carry the batch number for full traceability, plus the order number and site phase if needed.

Everything is CE and UKCA marked to BS EN 15048 and BS EN 14399, and every batch comes with test certificates to BS EN 10204, so compliance and paperwork are sorted before the delivery even lands.

Bags and labels are also fully recyclable polypropylene, which helps on the environmental side too.

How much time does your site lose each month just identifying and sorting fasteners on arrival?

Bolt specification mistakes that cause site delays

Wrong nut grade with galvanised bolts causes more rejected deliveries than most specifiers expect. Here are five things worth checking before your next order goes in.

Mixing standard-grade nuts with galvanised or sherardised set screws on CE (and UKCA) approved assemblies is a common one. Higher-grade nuts are often required to cope with the coating thickness and thread fit, so check this before assembly, not after.

Confusing HR and HV bolt assemblies trips people up too. They're both high-strength preloading systems under BS EN 14399, but the tightening methods and torque values differ, and getting it wrong affects preload accuracy.

Assuming preloaded (HSFG) assemblies can be de-assembled and reused is another. Once tensioned, they generally shouldn't be taken apart and refitted.

Overlooking DTI washers is worth a mention as well. BS EN 14399-9 direct tension indicators give a visual check on preload that torque alone won't confirm.

Which of these has caused the most hold-ups on your projects?

Traceable fasteners: what you're actually paying for

A cheaper bolt without paperwork can cost far more once it's on site. If something fails and there's no traceability, you can't prove where the steel came from, how it was tested, or whether it meets BS EN 14399 or BS EN 15048 at all.

Every fastener we supply comes with a Certificate of Conformity, and most with 3.1 Test Certificates covering full chemical and mechanical testing to BS EN 10204. CE and UKCA marked products also get a Declaration of Performance, so the paperwork matches the standard, not just the label.

Batch numbers are printed on weatherproof labels, and diameters are colour coded on site (red for M12, blue for M16, yellow for M20) so the right bolt goes into the right connection every time. Diameter and length are stamped on the bolt head too, as a second check.

That paper trail is what lets you trace a fastener from raw material to the exact structure it's holding together.

When did you last check whether your current supplier can actually produce full traceability documents on request?

CPD matters: know your fastener standards

Specifying the wrong bolting assembly can hold up a project long after the steel's gone up. That's why CPD in structural fastening isn't optional reading for engineers and specifiers, it's part of the job.

CE marking (paired with UKCA for GB placement) confirms a fastener meets the Construction Products Regulation. Non-preload assemblies need to comply with EN 15048-1, preload assemblies with EN 14399-1, each with its own labelling and Declaration of Performance.

Direct Tension Indicator washers, to BS EN 14399-9, let you confirm correct preload without relying on torque figures alone. Worth knowing before you're on site trying to sign off a connection.

Bodies like the Galvanizers Association run CPD seminars and technical publications on hot dip galvanizing, and New Steel Construction magazine is a solid ongoing resource for anyone specifying steel connections.

How much of your team's current CPD actually covers fastener standards rather than just the structural design side?

Questions worth asking before you order fasteners

Not every fastener supplier will give you a straight answer about test certificates, and that's worth knowing before an order goes out, not after.

Ask whether 3.1 certificates come as standard, or only 2.2. Ask if 3.2 certification is available for projects that need independent witness testing. Ask for full traceability back to the manufacturer, not just a batch number on a delivery note.

On preloaded assemblies (BS EN 14399), ask about minimum thread length and whether the assembly has been tested to BS EN 14399-2. On non-preloaded assemblies (BS EN 15048), ask the same about BS EN 15048-2. If hot dip galvanising is involved, ask how they've accounted for thread fit given the 50-80 micron average coating thickness, and whether hydrogen embrittlement has been managed through a non-acid cleaning treatment.

Confirm the product carries CE (and UKCA) marking, with a Declaration of Conformity supplied for each order. Confirm the supplier is approved to BS EN ISO 9001 and NHSS3.

What would your current supplier say if you asked all of that today?

Why Every Fastener We Dispatch Has Already Been Tested

When a structural bolting assembly reaches your site, the last thing you need is a compliance query or a failed inspection holding up the programme. That risk is removed before any product leaves our facility.

At Andrews Fasteners, all products are tested in-house before release to the customer, using specialist inspection equipment including tensile machines for bolts, setscrews and fullnuts, hardness testing (both portable and static), DTI/CLI testing, thread gauges, plating thickness testers, and suitability test machines for full assembly checks. Testing procedures cover dimensional checks, core and surface hardness (Leeb and Rockwell C), tensile, wedge and proof load tests, bend and compression tests, and assembly suitability tests to BS EN 15048-2 and BS EN 14399-2. Every inspection record is controlled through a fully integrated computerised quality system, providing complete traceability from manufacturer through to dispatch. 🔩

Our quality systems are independently assessed and certified to BS EN ISO 9001:2015, NHSS3, and CPR, and we hold CE approval for both BS EN 15048 non-preloaded and BS EN 14399 high-strength preloaded structural bolting assemblies. Test certificates are available to BS EN 10204 across multiple levels (2.1, 2.2, 3.1 and 3.2), so your documentation pack is covered from the outset. Does your current fastener supplier provide this level of pre-dispatch verification as standard? And what test certification level does your procurement specification typically require? We would be glad to discuss your project requirements directly. 📋

Waterworks Fastening: Standards and Materials That Matter

Specifying the wrong fastener for a waterworks or utilities application is a costly mistake — and in pressure pipe systems, the consequences go well beyond a delayed programme. T-Head bolt and nut assemblies compliant with ANSI/AWWA C111/A21.11 are the standard requirement for rubber-gasket joints on ductile-iron pressure pipe and fittings, and material selection is equally critical. Stainless steel grades A2 and A4 (including A2-70, A2-80, A4-70, and A4-80) are commonly specified for corrosion resistance in waterworks environments, while non-preload bolting assemblies must meet BS EN 15048 with dimensional requirements drawn from the relevant ISO product standards. For any CE-marked bolting assemblies, full traceability is non-negotiable — products must be supplied with a CE label and Declaration of Performance, and must be either assembly tested to BS EN 15048 or suitability tested to BS EN 14399. Andrews Fasteners holds full chemical and mechanical test certificates to BS EN 10204, including 3.1 certificates, and can provide 2.2 test certificates for stainless steel products where a 3.1 is not available or commercially practical. 🔩

What compliance challenges are you currently navigating on waterworks or utilities projects? Are traceability and test certification requirements becoming more stringent on the schemes you work on? Andrews Fasteners manufactures and distributes T-Head bolt assemblies for the waterworks industry and operates to a quality system independently assessed to BS EN ISO 9001:2015 and NHSS3 — so whether you need standard stock or bespoke fasteners manufactured to customer drawing, full regulatory compliance is built in from the outset. 📋

Now distributing Blind Bolt Company products

Blind-side fixing problems have a straightforward answer now: Andrews Fasteners is a distributor of Blind Bolt Company products.

If you've ever specified a connection where only one side of the steelwork is accessible, you'll know the usual workarounds involve welding, extra access, or redesigning the connection entirely. Blind bolts solve this by installing from one side only, with no access needed behind the material.

That matters for hollow structural sections, retrofit work, and refurbishment projects where getting behind the steel simply isn't possible.

As with the rest of our range, these come with full CE and UKCA marking, so traceability and compliance sit alongside the practical benefit.

Are you currently working on any projects where single-side access has been holding up the connection design?

Global Factory Partnerships Keeping UK Supply Chains Moving

When a large structural steel project needs thousands of certified bolting assemblies at short notice, the question isn't just about price. It's about whether your supplier can actually deliver, with full documentation, on time. Andrews Fasteners addresses this directly through a network of partner factories worldwide, allowing high-volume production, in-factory stockpiling, and the ability to supply containers direct from the manufacturing source.

Every product moving through this network carries CE marking (paired with UKCA), covers BS EN 14399 and BS EN 15048 bolting assemblies including DTIs, and is backed by 3.1 Test Certificates and Certificates of Conformity on every order. Crucially, Andrews Fasteners inspectors are stationed permanently at partner factories, running dimensional checks, hardness testing, tensile and proof load testing, and assembly suitability tests to BS EN 15048-2 and BS EN 14399-2 before anything ships. The company holds ISO 9001 and NHSS3 approval, and full traceability back to the manufacturer is standard. 🔩 Does your current fastener supplier offer that level of documented assurance at the factory level, or are certifications only verified after goods arrive in the UK? If you're procuring structural fasteners for construction, civil engineering, or waterworks projects and want to understand how a global manufacturing partnership can reduce lead times without compromising compliance, it's worth a conversation.

Fastener Delays on Site? Better Specification Fixes Most of It

Fastener-related delays are rarely about the bolts themselves. They almost always come down to poor specification, inadequate packaging, or missing documentation arriving on site. For procurement managers and engineers working to tight programmes, that distinction matters.

Several practical measures significantly reduce handling time and error on site. Colour-coded bolt bags (Red M12, Blue M16, Yellow M20, Green M24, Black M30) allow operatives to identify the correct diameter at a glance, cutting sorting time and reducing mis-assembly risk. Diameter and length stamped directly on the bolt head provides a secondary check, ensuring the correct fastener is used in each connection without cross-referencing paperwork. Supplying fully assembled bolt, nut and washer sets removes the persistent problem of component shortages mid-installation. On the compliance side, specifying CE & UKCA marked assemblies to BS EN 15048 (non-preloaded) or BS EN 14399 (preloaded), backed by 3.1 test certificates and a Declaration of Performance, means your documentation is in order before any questions are raised on site or during audit.

Andrews Fasteners has supplied CE & UKCA approved structural fasteners to the UK construction sector for over 115 years, with full traceability across stock and independently verified quality systems certified to BS EN ISO 9001:2015, NHSS3, and CPR. 🔩 Are you currently specifying fully assembled bolting assemblies, or sourcing components separately?
