CE and UKCA marking: what buyers need to check

Buying structural bolts for a project in Great Britain and Northern Ireland? The marking requirements differ, and getting them wrong can hold up a delivery.

CE marking is the base. Under the Construction Products Regulation, non-preloaded bolting assemblies must be supplied to EN 15048-1 and preloaded assemblies to EN 14399-1. UKCA sits alongside it for Great Britain, but it isn't recognised in the EU, and Northern Ireland still requires CE.

Every marked assembly should arrive with its label and paperwork: a Declaration of Performance for CE, and a UK Declaration of Conformity for UKCA.

Andrews Fasteners can supply both CE and UKCA marked assemblies. Since April 2024, that includes System HV preloaded assemblies.

When you receive marked bolts, which documents do you check first?

Why Gauge Calibration Is a Compliance Matter

An uncalibrated gauge can pass a bolt that should have been rejected, and the certificate that follows is then worth very little.

At Andrews Fasteners, initial inspection includes a full dimension check of internal and external threads using plug gauges and thread gauges. Those gauges only protect you if they are calibrated. The same applies to the equipment behind our in-house assembly, proof load, hardness and plating tests.

This matters because CE and UKCA marked bolt assemblies must be assembly tested (BS EN 15048) or suitability tested (BS EN 14399). They are supplied with a Declaration of Performance for CE, or a UK Declaration of Conformity for UKCA.

Do you ask suppliers how their inspection equipment is calibrated, or only to see the BS EN 10204 3.1 certificate?

T-Head Bolts for Waterworks, Direct from Factory

Specifying T-head bolts and hexagonal nuts for rubber-gasket joints on ductile-iron pressure pipe? Andrews Fasteners supplies them direct from the factory to customers worldwide.

They are made to American Water Works Association requirements, or to your own specification. Coatings are available across a range of finishes, including colour coding of nuts or full bolt and nut assemblies.

Manufacturing lead time can be as low as 45 days, with delivery straight from the factory to your site or depot. For the USA and Canada, we supply a minimum of 30 full containers.

Our product range carries CE and UKCA approvals, and we have traded since 1906, so compliance and traceability are part of how we work.

What size and finish do you most often need for your pressure pipe joints?

What the markings on a structural bolt tell you

A structural bolt head carries more information than most buyers check before it reaches site.

Our washers are marked with the headmark FAST (previously AND.), which identifies the manufacturer. Diameter and length are also stamped on the bolt head, so the wrong size is easy to catch before it goes into a connection.

Marking also matters for compliance. Non-preload assemblies are supplied to EN 15048-1 and preload assemblies to EN 14399-1, each with the correct CE and UKCA marking and the declaration of performance (DOP). Northern Ireland still requires CE marking, and the UKCA mark is not recognised in the EU.

When you receive a delivery, do you check the head marks and documentation against the specification before the bolts go out to site?

Torque Tool Calibration and Bolt Preload Accuracy

A torque wrench that has drifted out of calibration will tighten every bolt to the wrong figure, and nobody on site will see it.

Preload depends on the torque applied and on the k-Class of the assembly (K0, K1 or K2). If the tool reads wrong, the preload is wrong, even when the assembly itself is fully compliant with BS EN 14399 and CE & UKCA marked.

Direct Tension Indicator washers to EN 14399-9 take torque figures out of the equation. You check the tightness with feeler gauges, and they stay accurate whether the surface is oiled, coated or rusted.

Whichever method you use, the tool needs a current calibration record. Do your site teams check calibration dates before each tightening job, or only at scheduled intervals?

Check Fastener Coatings Before the Winter Weather Arrives

Autumn is the right time to inspect fastener corrosion protection, before wet and cold conditions start working on any weak spots.

Coating choice matters more as the weather turns. Sherardised finishes give a uniform zinc/iron alloy layer of 15-80 microns, which suits irregular shaped components and carries no risk of hydrogen embrittlement. Bright Zinc Plated finishes are only 5-10 microns, so protection is short term, and they can cause hydrogen embrittlement on products above grade 8.8.

If you're specifying replacements, ask for CE and UKCA marked assemblies to BS EN 14399 or BS EN 15048, supplied with 3.1 test certificates and full traceability.

Which fastener finishes are you most often asked to review on site at this time of year?

Manufacturing Fasteners to Your Drawing: What to Expect

If a standard catalogue part won't do, Andrews Fasteners can manufacture fasteners fully to your drawing, from eye bolts and U bolts to railway anchor studs and left hand thread studs.

Your drawing sets the specification. We then produce to our own Quality Control and Inspection Plans, using purpose-built inspection equipment. Our inspectors are based permanently at the manufacturing factories, so checks happen where the work is done.

Documentation follows the product. Certificates of Conformity come with every order, and 3.1 test certificates are supplied for most products. Where 3.1 isn't available or affordable, 2.2 certificates for tensile and proof load are an option. Finishes include Hot Dip Galvanised, Sherardized and Zinc Plating.

Orders can ship direct from the factory as full containers, by sea (around 30 days or more) or by air freight when time is short. Which finish or certificate level causes you the most difficulty when specifying bespoke fasteners?

Stainless steel isn't always the better fastener choice

Stainless steel has a reputation as the "best" corrosion protection you can buy. That's not always true once you factor in the application.

Stainless steel fasteners (grades A2 and A4) resist corrosion well because they're iron alloys with a minimum of 10.5% chromium content, giving broad oxidation resistance. But selecting the right type and grade has to start with the actual corrosion environment, not just the material's general reputation.

Hot dip galvanised coatings, tested to CE and UKCA approved EN ISO 1461, offer solid medium-to-long term protection at a fraction of the cost, and are often the better fit for structural steelwork where budgets and bulk supply matter.

Sherardising, meanwhile, avoids hydrogen embrittlement altogether, which makes it a strong option for smaller, high-strength components where stainless steel isn't necessary.

The right finish depends on the environment, the load, and the budget, not on which material sounds the most premium. What's the toughest corrosion challenge on your current project?

Fastener grade isn't just a number on the box

The grade stamped on a bolt tells you exactly how much load it can carry before it fails, and mixing that up on site causes real problems.

High-strength structural bolting assemblies for preloading (HR and HV systems) must comply with BS EN 14399, with hexagon bolts, nuts, and washers each certified to specific parts of that standard.

Non-preloaded assemblies follow BS EN 15048 instead, and the two families aren't interchangeable just because a bolt looks the same size.

Coatings matter too. Hot dip galvanising adds 40-180 microns of zinc for long-term corrosion protection, but that thickness changes the thread fit, which is why fullnuts are often tapped oversize afterwards to compensate.

For grade 12.9 and above, the high temperatures involved in galvanising can affect the metallurgical properties of the steel itself, so specification needs care at that end of the range.

Every assembly should arrive with a Declaration of Performance for CE and full traceability back to source.

How confident is your current supplier when you ask for that documentation?
