Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and rotational requirements in precision assemblies. The 20mm shoulder length acts as a precise locating diameter, eliminating the need for additional spacers or bushings in applications like machinery linkages, rotating shafts, and electronic enclosures. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it suitable for use in washdown environments, food processing equipment, and outdoor applications. The knurled socket head with a 4mm hex drive provides a secure grip for high-torque installation, preventing tool slippage and potential damage to the fastener. Its high tensile strength and defined shear strength ensure it can withstand significant operational loads, providing long-term reliability and reducing maintenance downtime in industrial settings.

Specification Summary & Compliance

This metric shoulder screw features an M5 x 0.8mm coarse thread with a Class 5g6g thread fit for standard clearance. The shoulder diameter is 8 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 20 mm with a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured to conform to the ISO 7379 standard and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
