Professional Applications & Engineering Value
This M5 brass tip set screw delivers exceptional engineering value in precision assembly applications where surface protection is critical. The 18-8 stainless steel body provides excellent corrosion resistance while maintaining Rockwell B80 hardness for reliable performance in vibrating environments. The soft brass tip (1.2mm length, 2.4mm diameter) acts as a sacrificial component, preventing marring and damage to expensive shafts, gears, and precision components during repeated adjustments. The 2.5mm hex drive in the headless design allows for flush mounting in confined spaces, while the Class 6g metric coarse threads ensure consistent clamping force in automation equipment, medical devices, and electronic enclosures where mar-free fastening is essential for both functionality and aesthetics.
Specification Summary & Compliance
This precision metric set screw features M5 x 0.8mm coarse threads with Class 6g thread fit tolerance for reliable engagement. Manufacturing complies with ASME B18.3.6M specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
