Key Features & Benefits at a Glance
- Superior holding power with precision cup point design that bites into mating surfaces to prevent loosening under vibration
- Exceptional durability from alloy steel construction with Rockwell C45 hardness for long-term performance in demanding applications
- Reliable thread engagement with Class 5g6g thread fit ensuring consistent fastening and load distribution
- Industry-standard compatibility meeting DIN 916/ISO 4029 specifications for seamless integration with metric components
- Secure installation using standard 4mm hex drive tools for precise torque control and reduced stripping risk
- Environmental compliance with RoHS 3 and REACH regulations for safe use across global industrial markets
- Optimized for coarse thread applications with M8 x 1.25mm configuration providing quick assembly and strong holding in softer materials
Professional Applications & Engineering Value
This M8 set screw delivers critical engineering solutions where vibration resistance and positional security are paramount. The alloy steel construction with Rockwell C45 hardness ensures the cup point maintains its bite force even under repeated stress cycles, preventing component slippage in machinery, automotive assemblies, and precision equipment. The Class 5g6g thread fit guarantees consistent clamping force across metric applications while the coarse thread pitch enables rapid installation in production environments. As a headless screw with 4mm hex drive, it provides flush mounting in confined spaces where protruding fasteners are impractical, making it ideal for shaft collars, gear hubs, and adjustable mechanisms requiring reliable set-and-forget functionality.
Specification Summary & Compliance
This metric set screw features M8 x 1.25mm coarse thread with Class 5g6g tolerance for precision fit. Manufactured to DIN 916 / ISO 4029 standards with 14mm length and right-hand thread orientation. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for international industrial applications.
