Professional Applications & Engineering Value
This M8 shoulder screw delivers exceptional engineering value in precision assembly applications where component alignment and corrosion resistance are critical. The 316 stainless steel construction combined with passivated finish provides superior protection against chemical exposure and atmospheric corrosion, making it ideal for food processing equipment, marine environments, and chemical handling machinery. The precisely machined 12mm shoulder length with controlled tolerances ensures accurate spacing and rotational alignment in assemblies, while the hex socket drive allows for clean installation in confined spaces. The Class 6g thread fit with 1.25mm coarse pitch enables quick assembly while maintaining vibration resistance in dynamic applications.
Specification Summary & Compliance
This precision metric shoulder screw features M8x1.25mm coarse pitch threading with Class 6g thread fit per ISO standards. The shoulder diameter maintains -0.025 to 0mm tolerance while shoulder length is controlled within 0 to 0.05mm tolerance for precise fitment. Manufactured from 316 stainless steel with passivated finish, the screw delivers 70,000 psi tensile strength and Rockwell B79 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental and safety standards.
