Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and wear challenges in industrial applications. The 316 Stainless Steel material provides outstanding resistance to chemicals and saltwater corrosion, making it perfect for food processing, marine, and chemical equipment. The 35mm shoulder length acts as a precise spacer or pivot, reducing wear on moving parts by preventing metal-to-metal contact. The Black Oxide finish adds an extra layer of protection against galling and minimizes light reflection. Combined with the coarse metric thread and hex socket drive, this screw ensures quick assembly, high clamp load retention, and reliable performance in machinery, automation systems, and precision instruments where durable fastening solutions are paramount.

Specification Summary & Compliance

This precision shoulder screw adheres to Metric standards with an M5x0.8mm thread size and pitch. The thread is manufactured to a Class 5g6g fit for consistent assembly. Key dimensional tolerances include a shoulder diameter of 6.5mm (-0.072 to -0.01 mm) and a shoulder length of 35mm (0 to +0.25 mm). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
