Professional Applications & Engineering Value
This M20 set screw delivers critical engineering solutions where component security is paramount. The alloy steel construction with Rockwell C45 hardness provides exceptional resistance to wear and deformation under heavy loads, while the cup point design creates permanent seating marks that prevent rotational movement in pulleys, gears, and collars. The headless hex drive configuration allows for flush mounting in machinery where protruding fasteners would interfere with operation. With coarse thread spacing and Class 5g6g thread fit, this metric set screw ensures rapid installation and reliable performance in automotive, manufacturing, and heavy equipment applications where vibration resistance and precise alignment are critical requirements.
Specification Summary & Compliance
This M20x2.5x40mm set screw features metric coarse threads with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and compatibility. Manufactured to DIN 916/ISO 4029 specifications for consistent quality and performance. 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 regulatory adherence.
