Key Features & Benefits at a Glance
- Maximum holding power through deep penetration with the cup point design that bites securely into mating surfaces
- Superior durability and wear resistance provided by alloy steel construction with Rockwell C45 hardness
- Reliable fastening performance ensured by Class 5g6g thread fit that maintains precision under vibration and load
- Efficient installation and removal with 10mm hex drive that prevents stripping and allows high torque application
- Broad industrial compatibility through compliance with DIN 916/ISO 4029 standards for metric coarse threads
- Safe for sensitive applications with full RoHS 3 and REACH compliance, free from hazardous substances
- Space-saving headless design ideal for applications where protruding fastener heads aren't feasible
Professional Applications & Engineering Value
This M18 set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The alloy steel construction with Rockwell C45 hardness provides the necessary strength to withstand high stress environments without deformation. The cup point design creates deep indentation in mating components, preventing rotational slippage in machinery, power transmission systems, and precision equipment. The metric coarse thread with 2.5mm pitch ensures quick installation while the Class 5g6g thread fit maintains dimensional stability under thermal cycling and mechanical loads. This headless screw is particularly valuable in confined spaces where traditional fastener heads would interfere with adjacent components, making it ideal for industrial set screws applications in manufacturing equipment, automotive assemblies, and heavy machinery.
Specification Summary & Compliance
This metric set screw features M18 x 2.5mm coarse thread spacing with Class 5g6g thread fit tolerance per ISO metric standards. Manufactured to DIN 916 ISO 4029 specifications, ensuring dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
