Content of tensile test report of bolts and screws: maximum force and tensile strength

Characteristic curve of bolt and screw tensile test:

reference resources:

Screws and bolts belong to fasteners. Due to different shapes and sizes and large load requirements, the difficulty of tensile test is increased. Also test the thread quality and fastener head strength.

Sansi Taijie's large tonnage tensile testing machine can fully meet the requirements of tensile testing of fasteners such as screws and bolts.


The national standard "GB / T 3098.1-2010 mechanical properties of fasteners bolts, screws and studs" has been implemented since October 1, 2011, replacing the original GB / T 3098.1-2000 standard.
