Professional Applications & Engineering Value

This M3 set screw is engineered to address common industrial challenges such as component slippage and fastener failure in high-stress assemblies. The black-oxide alloy steel material provides excellent corrosion resistance and strength, while the nylon tip offers a soft, non-marring contact surface that minimizes damage to shafts and components. Its headless design and hex drive allow for flush mounting and easy tightening in tight spaces, making it ideal for precision machinery, automotive systems, and electronic enclosures. The coarse thread and right-hand thread direction ensure quick installation and reliable holding power, reducing maintenance needs and enhancing operational efficiency in demanding applications.

Specification Summary & Compliance

This set screw features a metric thread size M3 with a 0.5 mm pitch and 6 mm length, manufactured to Class 5g6g thread fit for precise tolerances. It complies with ASME B18.3.6M specifications for dimensional accuracy and performance. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets environmental and safety standards for industrial use.
