- Precise component alignment enabled by the 5mm shoulder with tight diameter tolerance (-0.072 to -0.01 mm).
- High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for demanding applications.
- Secure, non-slip installation with a knurled head and 2.5 mm hex socket drive for reliable torque transfer.
- Consistent thread engagement ensured by Class 5g6g thread fit and M4x0.7 coarse pitch for quick assembly.
- Durable performance backed by Rockwell B55 hardness, resisting wear and deformation.
- Regulatory compliance meeting RoHS 3 and REACH standards for safe, global use.
Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address common assembly challenges in precision machinery, automation systems, and electronic enclosures. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, extending service life in humid or corrosive settings. The 5mm shoulder length with minimal tolerance ensures accurate positioning of rotating parts like gears and pulleys, reducing misalignment and vibration. The hex socket drive and knurled head texture facilitate secure tool engagement, preventing slippage during high-torque installations. With its metric coarse thread and robust tensile strength, it streamlines maintenance and enhances reliability in industrial fastener applications, from conveyor systems to robotic arms.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with M4x0.7 coarse threads and Class 5g6g thread fit for consistent performance. Shoulder dimensions include a diameter of 5 mm (tolerance: -0.072 to -0.01 mm) and length of 5 mm (tolerance: 0 to 0.25 mm). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and suitability for global industrial markets.
