Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision assemblies. The alloy steel core, hardened to Rockwell B71, ensures it withstands repetitive stresses without deformation, while the zinc plating provides a protective barrier against corrosion, extending service life in harsh conditions. The 8mm shoulder length and 7mm shoulder diameter deliver exact positioning for components like bearings, gears, or linkages, minimizing misalignment and wear. With a coarse metric thread (M5x0.8) and Class 6g tolerance, it facilitates quick, secure fastening in automated equipment, robotics, and automotive systems, reducing downtime and maintenance costs. Ideal for applications demanding reliable shoulder functionality, this screw enhances operational efficiency and durability in industrial fastening solutions.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a shoulder diameter tolerance of -0.036 mm to 0 mm and shoulder length tolerance of 0.07 mm to 0.15 mm, ensuring consistent fit in precision applications. The thread fit conforms to Class 6g per metric specifications, providing reliable engagement. It meets DIN 923 for manufacturing consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmental safety and global supply chain requirements.
