S-94285A325 M3 x 6 mm ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with serrations locking that prevents loosening under vibration and dynamic loads
• Exceptional durability and wear resistance provided by Alloy Steel construction and Rockwell C45 hardness
• Precise and reliable fit ensured by Class 6g thread fit and coarse pitch (0.5 mm) for easy assembly
• Secure, flush mounting with a headless design and cup tip that digs into surfaces without protruding
• Efficient installation and removal using a standard 1.5 mm hex drive tool
• Broad industrial compatibility with right-hand metric threads (M3) and compliance with ISO 4029 standards
• Environmentally responsible manufacturing meeting RoHS 3 and REACH regulations for safe use

Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in industrial assembly, such as component slippage and fastener failure under stress. The alloy steel material, combined with a Rockwell C45 hardness, provides excellent resistance to shear and tensile forces, making it ideal for high-vibration environments like machinery, automotive systems, and precision equipment. The cup tip design and serrations locking create a permanent, flush grip on shafts, gears, and collars, preventing rotational movement without damaging the mating surface. Its Class 6g thread fit and coarse pitch metric thread ensure quick, reliable installation with standard tools, reducing assembly time and maintenance needs in industrial set screw applications.
