Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address critical alignment and corrosion challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to chemicals and moisture, making it suitable for marine, chemical processing, and food industry equipment. The integrated 14mm shoulder acts as a precise pivot or spacer, maintaining accurate component positioning while the Class 5g6g thread ensures secure fastening without loosening. The socket head with 3mm hex drive allows for compact installation in confined spaces, which is vital in machinery, automation systems, and electronic enclosures where reliability and repeatability are paramount.
Specification Summary & Compliance
The screw features a metric M4x0.7 coarse thread with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy. Shoulder diameter tolerance is -0.072 to -0.01 mm and shoulder length tolerance is 0 to 0.25 mm for precise fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial and consumer products requiring environmental safety.
