Key Features & Benefits at a Glance
- Maximum holding power with 90° cone point design that bites deeply into materials for secure, vibration-resistant fastening
- Superior corrosion resistance through zinc-plated alloy steel construction, extending service life in demanding industrial environments
- Precise torque transmission via 4mm hex drive that prevents tool slippage and ensures consistent installation force
- Reliable thread engagement with Class 5g6g coarse thread fit that accommodates minor material variations while maintaining secure fastening
- Exceptional durability from Rockwell C45 hardness rating that resists deformation under high stress conditions
- Space-saving headless design allowing flush mounting where protruding fastener heads are impractical
- Global compliance assurance meeting DIN 914/ISO 4027 standards plus RoHS 3 and REACH environmental regulations
Professional Applications & Engineering Value
This M8 set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and secure fastening. The zinc-plated alloy steel construction provides excellent corrosion protection while maintaining the Rockwell C45 hardness needed for high-stress applications. The 90° cone point creates concentrated pressure that prevents shaft slippage in pulleys, gears, and collars, while the headless design enables flush installation in confined spaces. The coarse thread with 1.25mm pitch ensures rapid installation and reliable performance in materials where fine threads might strip. These metric set screws are particularly valuable in machinery assembly, automotive components, and precision equipment where vibration resistance and positional accuracy are paramount.
Specification Summary & Compliance
This set screw features M8 x 1.25mm coarse thread with Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional accuracy and reliable performance. Manufactured to DIN 914/ISO 4027 specifications with 35mm length and 4mm hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications with strict chemical substance restrictions.
