Fastener Testing

Our 1500kN tensile machine is dedicated to fastener testing and includes an Epsilon bolt extensometer that enables us to accurately determine the proof/yield stress of finished fasteners, as well as proof load measurements. 
Our ever-expanding tooling collection enables us to test a wide range of metric and UN thread sizes.

Testing of Studs, Bolts and Nuts

  • Tensile full size Incl. proof & elongation using an Extensometer.
  • Tensile  (UTS only) with or without wedge
  • Proof load only
  • Proof load with wedge test / UTS

We are accredited to test fasteners to National & International Standards made from a range of materials.

Analytical Testing

The chemical analysis department was established to complement the successful mechanical and metallurgical departments.

The following is a summary of our analytical testing capabilities:

  • LECO CS744 – C&S analyser (combustion)
  • LECO ON736 – O&N analyser (thermal fusion)
  • LECO H836 – H analyser (thermal fusion)
  • OES (optical emission spectroscopy) analysers - SpectroMAXx04, SpectroMAXx08

We also use Leco and Eltra analysers to carry out gas determinations for carbon, sulphur, oxygen and nitrogen.

We offer a same day service for analytical testing by arrangement.

Corrosion Testing

Understanding how materials behave in operating environments is essential. Using temperature controlled baths, we can test many samples simultaneously. Temperature control can be automated and recorded electronically if required. Hotplates are used to test materials in boiling solutions.

We perform a range of standard corrosion tests, including:

  • G48 standard test for pitting and crevice corrosion resistance in stainless steels and related alloys using a ferric chloride solution in temperature controlled baths. Tests performed to ASTM G48 methods A & B / ASTM A923 METHOD C.
  • Intergranular corrosion susceptibility testing on wrought nickel-rich chromium-bearing alloys using copper/copper sulphate-16% sulphuric acid solution. Tests performed to ASTM A262 practice E.
  • Huey tests for intergranular corrosion susceptibility in wrought nickel-rich chromium-bearing alloys using nitric acid. Tests performed to ASTM A262 practice C.
  • G28 test for intergranular corrosion susceptibility in wrought nickel-rich chromium-bearing alloys using boiling ferric sulphate-sulphuric acid solution. Tests performed to ASTM G28.


We have extensive machining capabilities that allows us to machine a wide range of sample sizes and material grades.

Our equipment, the quality controls we have in place, and the skill of our machinists, means we can prepare and test specimens from 3.99mm to 20mm section that are suitable for many sectors in our industry.

Heat Treatment Of Test Samples

We have four dedicated furnaces for carrying out proof and post weld heat treatments. Two are calibrated to API 6A and two to AMS2750, required for heat treating to tight tolerances. We are able to apply oil or water quench with agitation to meet relevant standards.

Details of heat treatment applied to test pieces are included on our test certificates; we are able to produce and e-mail or print furnace charts thanks to the individual temperature recorder.

Failure Investigations

Our failure investigations service employs all testing methods available for full material examination to provide essential evidence in the identification of the cause of failure.
