- Precise component alignment due to the 10mm shoulder length with controlled tolerances, reducing assembly errors.
- High strength and durability offering 70,000 psi tensile strength and Rockwell B55 hardness for reliable performance under load.
- Secure and efficient installation with a 3 mm hex socket drive, preventing cam-out and ensuring tight fastening.
- Accurate thread engagement with Class 5g6g thread fit, minimizing the risk of cross-threading in metric assemblies.
- Environmental compliance meeting RoHS 3 and REACH standards, ensuring safety and regulatory adherence.
- Versatile coarse thread pitch (0.8mm) for quicker installation and better resistance to vibration loosening.
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in machinery. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for applications in humid or chemical-exposed settings like automotive assemblies and electronic enclosures. The 10mm shoulder length acts as a precise pivot or spacer, ensuring accurate positioning of parts like gears and pulleys, which reduces friction and extends equipment life. With a hex socket drive and coarse thread pitch, it allows for rapid, secure fastening even in high-vibration environments, streamlining maintenance and improving overall assembly reliability.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy for consistent performance. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, supporting precise engineering requirements. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances for safe industrial use.
