Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and durability challenges in industrial settings. Manufactured from 18-8 stainless steel, it provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive assemblies, and food processing equipment exposed to moisture or chemicals. The hex socket head with a knurled texture ensures a firm grip, reducing the risk of cam-out and damage during high-torque installation. The Class 5g6g thread fit and coarse 1.75mm pitch facilitate quick and reliable assembly, minimizing production downtime. The precision-machined shoulder acts as a reliable bearing surface or pivot point, maintaining exact part alignment in rotating mechanisms or jigs, thereby enhancing operational accuracy and reducing wear.

Specification Summary & Compliance

This metric shoulder screw adheres to precise dimensional standards, including a Class 5g6g thread fit for consistent engagement. The shoulder diameter is maintained at 12 mm with a tolerance of -0.072 to -0.01 mm, and shoulder length tolerance is tightly controlled at -0.05 to 0.05 mm. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
