Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and durability challenges in precision industrial applications. The steel construction combined with a Rockwell C20 hardness offers robust resistance to shear forces and wear, making it ideal for machinery linkages, rotating assemblies, and automation systems. The 9mm shoulder diameter with minimal tolerance ensures exact positioning, reducing misalignment and component stress. Featuring a coarse pitch metric thread (M8x1.25) and external hex drive, it simplifies installation in high-volume production while maintaining Class 6g thread accuracy for secure, vibration-resistant connections. This design is particularly valuable in sectors like automotive, robotics, and heavy equipment, where precision shoulder bolts enhance operational reliability and reduce maintenance downtime.
Specification Summary & Compliance
This M8x1.25 shoulder screw adheres to DIN 609 specifications, with a Class 6g thread fit and shoulder diameter tolerance of 0.001 to 0.01 mm for high precision. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
