Mechanical property testing of bolt fasteners


Fasteners are usually classified into grades, which can withstand specific proof loads, and their yield strength and tensile strength have exceeded predetermined values. Manufacturers may also grade fasteners using specific product classifications. In the process of designing safe and reliable products, it is essential to ensure that fasteners meet the published classification standards. To this end, fastener manufacturers have established test procedures to check product quality and design.

Due to the different shapes and sizes of fasteners, large load requirements and requirements, the tensile test of fasteners is more difficult. Also test the thread quality and fastener head strength.


Executive standard: GB/T 3098.1-2010 Mechanical properties of fasteners Bolts, screws and studs


Solution


Shoulder clamp and short bolt connector for fastener clamp shall meet the test requirements. Ensure the robustness of fasteners of any size, shape or strength.
