Professional Applications & Engineering Value

This M4 shoulder screw is engineered to solve critical alignment and pivoting challenges in precision assemblies. The unthreaded shoulder acts as a precise datum, allowing components like gears, bearings, or linkages to rotate or be positioned with minimal play. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it a robust choice for machinery, automotive sub-assemblies, and electronic enclosures exposed to varying operational conditions. The coarse thread pitch and 10mm thread length provide rapid installation and strong holding power. Its socket head design is ideal for applications with limited space, ensuring a reliable, flush fit that withstands high torque without stripping, thereby reducing assembly time and improving the longevity of the final product.

Specification Summary & Compliance

This precision shoulder screw features an M4 x 0.7mm coarse metric thread with a Class 5g6g thread fit for consistent assembly. The shoulder diameter is manufactured to a tight tolerance of -0.072 to -0.01 mm. The component is produced in accordance with the ISO 7379 standard, ensuring dimensional accuracy and performance reliability. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated markets.
