We propose suitable fastening conditions to our customers based on the screw examination tests!
The proposal of better contract terms is where the true value of a fastener manufacturer is demonstrated! Our company offers a wide range of measuring equipment specifically for fasteners.
At Yamashina, we offer a variety of measuring equipment specifically designed for fasteners, enabling us to propose better fastening conditions. With the support of our excellent senior engineers, who possess extensive testing know-how backed by a long history and the latest technology, we conduct tests and analyze their results to suggest optimal fastening conditions to our customers. **Test Items:** - Tensile strength (yield and fracture) - Shear strength - Fatigue testing (conducted externally) - Tightening fracture testing - Tightening relaxation testing - Torque-axial force relationship examination testing - Axial force creep confirmation testing - Threading rotation speed dependency testing - Temperature distribution testing during threading - Friction coefficient calculation - Cold and heat testing - Alternating immersion testing in saltwater - Salt spray testing - Electrical insulation evaluation testing - Ground bolt continuity testing - Chip analysis - Vibration testing (bolt standalone evaluation) - Plastic zone examination, etc. Please note that the test content may be constrained by bolt diameter and length. Additionally, costs may be high depending on global compliance and the types of tests conducted. There are also tests not listed above that can be performed using external testing facilities, and reports can be provided for those as well. Please feel free to consult us, including for cost estimates.
