• Precise, secure fastening ensured by M6 coarse thread with Class 5g6g fit, providing reliable engagement and vibration resistance.
• Protects sensitive surfaces using a soft brass tip (1.6 mm length, 3.2 mm diameter) to prevent marring and damage during installation.
• Easy installation in confined spaces with a headless, hex drive design that allows flush mounting and tool access with a 3 mm hex key.
• Compliance with international standards including ASME B18.3.6M, ensuring consistent quality and interchangeability for industrial applications.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting global regulatory requirements for safe use.
• Right-hand thread direction for straightforward, intuitive assembly in standard metric fastener systems.

Professional Applications & Engineering Value

This M6 set screw is engineered to address common industrial challenges such as component slippage and surface damage in precision assemblies. Made from black-oxide alloy steel, it offers enhanced wear resistance and a protective finish that reduces oxidation in demanding environments. The coarse thread with Class 5g6g tolerance ensures quick, reliable fastening even in applications subject to vibration, while the brass soft tip distributes pressure evenly to safeguard delicate materials like shafts or gears. Ideal for machinery, automotive, and electronics, this headless screw with a hex drive provides a low-profile solution that maintains alignment and security without protruding, making it a top choice for engineers seeking durable, RoHS and REACH compliant fasteners.

Specification Summary & Compliance

This set screw features a metric M6 x 1 mm thread with Class 5g6g thread fit for precise dimensional accuracy, adhering to ASME B18.3.6M specifications. It is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence. The right-hand coarse thread spacing and 20 mm length provide consistent performance in industrial fastening applications.
