Professional Applications & Engineering Value
This M3 set screw with soft brass tip delivers critical protection for precision components in industrial machinery, automation systems, and electronic enclosures. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining Rockwell B80 hardness for reliable clamping force retention. The headless hex drive design enables installation in space-constrained applications where traditional fastener heads would interfere. The Class 6g thread fit ensures precise engagement with mating components, preventing loosening from vibration while the brass tip material eliminates galling and surface damage to shafts, gears, and collars. This combination of features makes it ideal for precision positioning applications requiring repeated adjustments without compromising component integrity.
Specification Summary & Compliance
This metric set screw features M3 x 0.5mm coarse thread spacing with Class 6g thread fit tolerance for precise engagement. The 3mm length with 1.5mm hex drive provides compact installation capabilities. Manufacturing and dimensional specifications conform to ASME B18.3.6M standards, ensuring interchangeability and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict chemical substance restrictions.
