Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address critical alignment and wear challenges in precision assemblies. The 18-8 stainless steel core provides excellent resistance to rust and chemical exposure, while the black oxide finish adds an extra layer of protection against abrasion and galling. The integrated 10mm shoulder acts as a precise pivot or spacer, minimizing part movement and reducing wear on mating components in machinery, automation systems, and conveyor setups. With its socket head design and hex drive, it allows for compact installation in confined spaces, ensuring high clamp load without slippage. Ideal for use in industrial equipment, robotics, and fixture manufacturing, this screw enhances assembly longevity and reduces maintenance downtime.
Specification Summary & Compliance
This shoulder screw conforms to ISO 7379 standards, with a Class 5g6g thread fit for consistent engagement. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material traceability for global supply chains.
