We test tensile strength and min. ultimate tensile strength

A fastener’s tensile strength is affected e.g. by the material, the design of the thread and by heat. Properties that define a fastener’s tensile strength include e.g. min. ultimate tensile strength and proof stress. Together with the forces to which the bolted joint is exposed, these constitute important criteria for you to be able to select the right product.

One fundamental requirement for each fastener is that it must withstand the loads it is expected to experience during its specified service life. The nature of the loads, the design and the material’s properties, along with the surrounding environment, all influence the damage or deformation that can arise in the bolted joint.

Thanks to our test laboratory, we can assure ourselves that our fasteners will keep the promises we make. The documentation that accompanies our deliveries confirms the results regarding tensile strength indicated by the control tests.
