Professional Applications & Engineering Value

This M4 shoulder screw is engineered to address critical alignment and durability challenges in precision industrial assemblies. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for applications in machinery, automotive, and electronics where exposure to moisture or chemicals is a concern. The 15mm shoulder length acts as a precise pivot or spacer, eliminating the need for additional bushings and reducing assembly complexity. Combined with the hex socket drive and knurled head, it ensures secure fastening in high-vibration environments. The metric thread with Class 5g6g fit guarantees consistent performance, supporting efficient production and maintenance cycles.

Specification Summary & Compliance

This shoulder screw features a M4 x 0.7mm coarse thread with Class 5g6g thread fit, ensuring precise tolerance. The shoulder diameter is 5 mm with a tolerance of -0.072 to -0.01 mm, and shoulder length is 15 mm with a tolerance of 0 to 0.25 mm for accurate fit. It is manufactured in compliance with ISO 7379 standards and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for global use.
