Professional Applications & Engineering Value

This M12 shoulder screw delivers critical engineering value in precision assembly applications where component alignment and rotational stability are paramount. The 35mm shoulder length acts as a precise locating dowel, eliminating the need for additional alignment components in machinery, conveyor systems, and automated equipment. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance in manufacturing environments exposed to moisture, chemicals, or outdoor conditions. The hex socket drive with knurled head texture ensures maximum torque transfer while preventing tool slippage during high-torque installation. With its Class 5g6g thread fit and coarse thread pitch, this metric shoulder screw enables rapid assembly in production lines while maintaining secure fastening in vibrating equipment, reducing maintenance downtime and improving operational reliability.

Specification Summary & Compliance

This precision shoulder screw features M12x1.75mm coarse threads with Class 5g6g thread fit per metric standards. The shoulder diameter maintains tight tolerance of -0.04 to -0.01 mm with shoulder length tolerance of 0 to 0.25 mm for precise component positioning. Manufactured to industrial standards with Rockwell B55 hardness and 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety.
