- Regulatory compliance assurance meeting ASME B18.3.6M standards and environmental directives
Professional Applications & Engineering Value
This M3 hex headless set screw delivers exceptional engineering value in precision assemblies where space constraints and vibration resistance are critical. The 18-8 stainless steel construction provides reliable corrosion resistance for machinery, automotive components, and electronic enclosures exposed to moisture or chemicals. The brass tip prevents galling and damage to shafts and rotating elements, while the Class 6g thread fit maintains positional accuracy in high-vibration environments. Its headless design and 1.5mm hex drive enable flush mounting in tight spaces, making it ideal for securing pulleys, gears, and collars where protrusions are unacceptable. The combination of Rockwell B80 hardness and coarse thread spacing ensures repeated installation without stripping, providing long-term reliability in industrial maintenance and OEM applications.
Specification Summary & Compliance
This metric set screw features M3 x 0.5mm thread with Class 6g tolerance for precision fit, right-hand thread direction, and 6mm length. Manufactured to ASME B18.3.6M specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industries.
