Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 stainless steel material provides excellent resistance to corrosion and chemicals, making it suitable for machinery, automotive assemblies, and outdoor equipment. The 150mm shoulder length acts as a precise pivot or spacer, reducing wear on moving parts and ensuring accurate positioning in jigs, fixtures, and rotating mechanisms. Combined with the black oxide finish, it offers added protection against abrasion and galling. The coarse thread pitch and hex drive facilitate quick, secure fastening, minimizing assembly time and maintenance needs in high-stress environments.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit per metric standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm for precise engineering. It is manufactured to comply with ISO 7379 specifications and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and international quality standards.
