• Guaranteed dimensional accuracy and quality through compliance with DIN 916 and ISO 4029 standards, ensuring fit and function.
• Safe for use in regulated industries as it is RoHS 3 and REACH compliant, meeting environmental and health safety standards.

Professional Applications & Engineering Value

This M8 set screw is engineered to address critical challenges in industrial assembly, such as component slippage and fastener failure under stress. Manufactured from high-strength Alloy Steel and heat-treated to a Rockwell C45 hardness, it provides exceptional resistance to wear and deformation. The fine thread with a 1mm pitch offers increased surface contact, enhancing clamping force and vibration resistance in precision machinery, automotive systems, and tooling jigs. The headless design and cup tip allow for flush mounting and secure positioning without protruding parts, making it ideal for applications where space is limited and a reliable, tamper-resistant fastening solution is required. Compliance with DIN 916 and ISO 4029 ensures consistent quality and performance in metric fastening systems.
