- High-strength durability with Rockwell C28 hardness, ensuring reliable performance under repeated tightening and vibration
- Precision thread engagement with Class 5g6g fit and coarse M4x0.7mm threads for quick, secure fastening and reduced cross-threading risk
- Space-saving headless design with 2mm hex drive, ideal for confined spaces and flush mounting applications
- Regulatory compliance assurance meeting ASME B18.3.6M, RoHS 3, and REACH standards for global industrial use
- Optimized tip geometry featuring 2.4mm diameter brass tip over 1.2mm length for concentrated pressure distribution
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for precision assembly challenges. The M4 coarse thread with Class 5g6g tolerance provides rapid installation while maintaining vibration resistance in dynamic environments. The soft brass tip specifically addresses the industrial need for secure fastening without surface damage, making it ideal for securing gears, pulleys, and collars on finished shafts. The headless hex drive design enables flush mounting in space-constrained applications while the black-oxide surface treatment enhances corrosion protection in manufacturing, automation, and machinery sectors where reliability and component preservation are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3.6M specifications with Class 5g6g thread fit ensuring dimensional accuracy for metric coarse threads (M4x0.7mm). The 8mm length maintains precise engagement while the 2mm hex drive provides secure tooling. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial fastener applications.
