Professional Applications & Engineering Value
This M4 set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and secure positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in humid or chemical environments, while the hex socket drive ensures reliable torque transmission without cam-out. The 90° cone point creates concentrated pressure for superior grip on shafts, gears, and pulleys, preventing rotational slippage in power transmission systems. With its coarse thread pitch and Class 6g thread fit, this headless set screw offers quick installation and consistent performance in automotive, manufacturing, and precision equipment applications where space constraints and vibration are common challenges.
Specification Summary & Compliance
This metric set screw features M4 x 0.7mm coarse threads with Class 6g thread tolerance ensuring precise fit and reliable performance. Manufactured to DIN 914 and ISO 4027 standards, the fastener maintains dimensional accuracy and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making it suitable for use in regulated industrial environments and international markets.
