Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address critical alignment and wear challenges in precision industrial assemblies. Manufactured from 316 stainless steel, it offers exceptional resistance to corrosion and chemicals, making it suitable for medical devices, food processing equipment, and marine applications. The 35mm shoulder length provides a precise bearing surface, reducing wear on mating parts and maintaining alignment under load. The hex socket drive and knurled head texture facilitate secure installation in confined spaces, while the Class 5g6g thread fit ensures reliable fastening in metric machinery. This combination of material and design delivers long-term durability and reduces maintenance cycles in high-stress environments.
Specification Summary & Compliance
This shoulder screw features an M4 x 0.7mm coarse thread with a Class 5g6g thread fit per metric standards. The shoulder diameter is 5mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 35mm with a tolerance of 0 to 0.25 mm. It is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated industries.
