Fastener Testing

21 September 2018





Special Testing Ltd have for a number of years regularly carried out testing requirements for companies across the UK involved in the fastener industry and to enable us to facilitate our services further, we have recently invested in a new 1500 kN servo-hydraulic universal testing machine capable of testing finished fasteners up to M60.


We are now UKAS 17025 accredited for: -


  • Proof load testing of bolts, screws and studs
  • Proof load testing of nuts
  • Tensile testing (including wedge loading) of bolts, screws and studs


Testing is carried out to international standards BS EN ISO 898-1, BS EN ISO 898-2, BS EN 3506-1, BS EN 3506-2, ASTM A370 (Annex 3), ASTM F606/F606M and ASTM A962/A962M and we can also accommodate further standards when required through our flexible scope of accreditation.


Should you have any requirements for testing of fasteners or require any further information, please do not hesitate to contact: -
