Threaded Fasteners inspection of bolts, screws, studs, nuts, pins, washers, also rivets and other related fasteners.


Are you receiving what you ordered? or are they counterfeit!

LMATS is NATA & ILAC MRA recognised ISO 17025 Testing Laboratory "The International acceptance of technical test and calibration data for exported goods" resulting in "a product tested once, accepted everywhere". 

LMATS Threaded Fastener inspection services Services for Pre Shipment and Post Delivery inspection before to acceptance, thus making sure the quality you ordered is the quality you received. The correct material specification, correct strength, correct dimensions, etc.

Specialised Fastener Testing of bolts, nuts, washers and all types of fasteners.

Do the fasteners you are procuring meet the correct specification for the job?

Whether they are required to withstand corrosive conditions of marine and subterranean environments or the stresses and fatigue conditions of rotating equipment, or any other critical
application, a high level of quality assurance is essential for  ensuring that the right fasteners are installed.

LMATS provide comprehensive testing of all sizes and grades:

  • Proof Load Test
    Assess the capacity to hold a specified load
  • Wedge Tensile Test –
    Assess maximum load capacity.
  • ROCAP (Rotational Capacity) and Assembly Tests
    Assess the performance of a bolt, nut and washer set
  • Hardness Test
    Core and surface
  • Chemical Analysis
    Grade identification and compliance
  • Coating Thickness
    Corrosion resistance potential.
