  • Optimized for heavy-duty use with precise M8 x 35mm metric dimensions, offering a robust solution for machinery and equipment

Professional Applications & Engineering Value

This M8 alloy steel set screw is engineered to address common industrial challenges such as component slippage and fastener failure under stress. The square head design allows for high-torque applications without cam-out, while the extended tip ensures deep penetration and firm seating in materials, minimizing loosening from vibrations. Made from alloy steel with Rockwell C22 hardness, it withstands heavy loads and repetitive use in machinery, automotive, and construction sectors. The coarse metric thread (1.25mm pitch) facilitates rapid installation and removal, reducing downtime. Compliant with DIN 479, it guarantees precision and reliability, making it ideal for industrial fastening where durability and regulatory adherence are critical.

Specification Summary & Compliance

This set screw features precise metric dimensions (M8 x 1.25mm pitch x 35mm length) with a Class 6g thread fit for standard tolerance, ensuring consistent performance. The extended tip has a diameter of 5.5mm with a tolerance of -0.18mm to 0 and length of 2.25mm with a tolerance of -0.25mm to 0. It is manufactured in accordance with DIN 479 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its safety and environmental standards.
