Professional Applications & Engineering Value
This M8 x 1.25mm metric set screw delivers exceptional engineering value in demanding industrial environments where vibration resistance and permanent positioning are critical. The alloy steel construction with Rockwell C45 hardness provides superior strength that prevents stripping and maintains clamping force under extreme conditions. The cup tip design creates concentrated pressure points that securely bite into shaft surfaces, eliminating slippage in power transmission components, pulleys, and gears. With its coarse thread pitch and Class 5g6g thread fit, this headless screw offers quick installation while maintaining precise alignment in machinery, automotive, and manufacturing equipment where reliability cannot be compromised.
Specification Summary & Compliance
This set screw features M8 x 1.25mm coarse thread with Class 5g6g thread fit per ISO metric standards, ensuring dimensional accuracy and interchangeability. Manufactured to DIN 916 and ISO 4029 specifications with a 10mm length and 4mm hex drive. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use across various industrial sectors without restriction.
