• Precise and reliable fastening with Class 5g6g thread fit, minimizing the risk of cross-threading and ensuring consistent performance in demanding applications.
• Optimized for high-torque installation using a 12 mm hex drive, providing a secure grip and reducing the risk of tool slippage during assembly.
• Superior material durability from alloy steel, offering excellent resistance to wear and fatigue for long service life in industrial environments.
• Secure point contact and minimal surface marring with a cup tip design, ideal for positioning components without damaging the contact surface.
• Guaranteed dimensional interchangeability through compliance with DIN 916 and ISO 4029 standards, ensuring compatibility with other metric components.
• Safe for use in regulated industries as it is RoHS 3 and REACH compliant, meeting stringent environmental and safety standards.

Professional Applications & Engineering Value

This M24 set screw is engineered to solve critical fastening challenges in heavy-duty machinery, automotive assemblies, and precision equipment. The alloy steel material, hardened to Rockwell C45, provides the necessary strength to withstand high vibrational loads and shock, preventing loosening in dynamic environments. Its coarse thread (3mm pitch) and Class 5g6g thread fit ensure quick assembly and reliable clamping force, reducing installation time while maintaining joint integrity. The headless design with a hex drive allows for flush mounting in confined spaces, making it ideal for applications where protrusion is not permissible. Compliant with DIN 916/ISO 4029, this screw offers a trusted solution for engineers seeking durable, standardized metric fasteners that deliver consistent performance and reduce maintenance downtime.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 5g6g thread fit per ISO metric specifications, ensuring excellent interchangeability and tolerance control. It is manufactured in compliance with DIN 916 ISO 4029, guaranteeing consistent quality and performance. The product meets key regulatory requirements, including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for use in environments with strict environmental and safety regulations.
