Professional Applications & Engineering Value

This M3 metric set screw with black-oxide alloy steel construction addresses critical challenges in precision assembly applications. The green nylon 6/6 tip provides reliable self-locking capability that prevents loosening from vibration, eliminating the need for additional locking components in machinery, automotive, and electronic assemblies. The coarse thread design with 0.5 mm pitch ensures quick installation while maintaining holding power in soft materials. The headless configuration and compact 5 mm length make it ideal for space-constrained applications where protruding fasteners are not feasible. With Rockwell C28 hardness, this hex drive set screw maintains structural integrity under repeated adjustments, providing long-term reliability in demanding industrial environments.

Specification Summary & Compliance

This precision fastener features M3 x 0.5 mm coarse thread with Class 5g6g thread fit tolerance for consistent mating performance. Manufactured to ASME B18.3.6M specifications, the set screw ensures dimensional accuracy and interchangeability. 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 requiring strict material and safety standards.
