• Easy installation and removal with 4mm hex drive providing secure tool engagement without stripping
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use across industries

Professional Applications & Engineering Value

This M8 set screw with black-oxide alloy steel construction addresses critical engineering challenges in industrial machinery, automation systems, and precision equipment. The headless design enables flush mounting in confined spaces while the brass tip prevents damage to shaft surfaces during installation. With coarse thread spacing and Class 5g6g thread fit, this fastener maintains secure positioning even under continuous vibration and dynamic loads. The Rockwell C28 hardness ensures the screw withstands repeated adjustments without deformation, making it ideal for set collar applications, gear positioning, and pulley fastening where reliability is paramount.

Specification Summary & Compliance

This metric set screw features M8 x 1.25mm coarse thread with Class 5g6g tolerance for precision fit. Manufactured to ASME B18.3.6M specifications with Rockwell C28 hardness alloy steel and 4mm hex drive. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial applications.
