Professional Applications & Engineering Value
This M18 set screw delivers exceptional engineering value in industrial applications where vibration resistance and permanent fastening are critical. The alloy steel construction with Rockwell C45 hardness provides superior tensile strength, preventing stripping or deformation under high torque loads. The cup point tip bites securely into mating surfaces, creating permanent seating that maintains positional accuracy in machinery, automotive components, and precision equipment. With coarse thread spacing and Class 5g6g thread fit, installation is efficient while ensuring reliable engagement in both soft and hard materials. The headless hex drive design allows for flush mounting in confined spaces, making these metric fasteners ideal for applications where protruding fastener heads would interfere with operation or safety.
Specification Summary & Compliance
This metric set screw features M18 x 2.5mm coarse thread with Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional accuracy. Manufacturing complies with DIN 916 and ISO 4029 specifications for dimensional and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest substance restriction requirements for industrial applications worldwide.
