Professional Applications & Engineering Value

This M4 shoulder screw is engineered to address critical alignment and wear challenges in precision assemblies. The 16mm shoulder length provides a stable pivot or spacer, reducing friction and component misalignment in machinery, automotive, and electronics. Made from 18-8 stainless steel, it resists rust and chemical exposure, extending service life in humid or corrosive settings. The hex socket head with knurling ensures secure tool grip during installation, minimizing slippage and damage. With a coarse thread pitch and Class 5g6g thread fit, it offers reliable fastening in high-vibration environments, making it ideal for industrial shoulder screw applications where precision and durability are paramount.

Specification Summary & Compliance

This screw features a metric M4 x 0.7mm coarse thread with Class 5g6g thread fit, ensuring dimensional accuracy per ISO standards. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, supporting precise engineering requirements. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial use.
