Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel material, ideal for harsh industrial environments and chemical exposure
- Precise alignment and positioning enabled by the accurately machined shoulder with tight diameter and length tolerances
- High mechanical strength offering 70,000 psi tensile strength and Rockwell B79 hardness for reliable, long-term fastening
- Secure hex drive engagement with 2.5 mm socket head for easy installation and high torque transmission without stripping
- Consistent thread performance with Class 6g fit and coarse M4x0.7mm thread for quick assembly and vibration resistance
- Enhanced durability from passivated finish that increases surface hardness and extends service life
- Global compliance assurance meeting RoHS 3 and REACH regulations for safe use in international markets
Professional Applications & Engineering Value
This M4 shoulder screw in 316 stainless steel delivers critical engineering solutions for precision machinery, automation systems, and medical devices. Its precise shoulder fit with 5mm diameter and 3mm length tolerances ensures accurate component alignment, eliminating play and reducing wear in rotating assemblies. The socket head design with hex drive allows compact installation in confined spaces while maintaining high clamp force. With excellent corrosion resistance from both the material and passivated finish, it performs reliably in demanding conditions including marine, chemical processing, and food equipment applications where moisture and corrosive agents are present.
Specification Summary & Compliance
This precision shoulder screw features M4x0.7mm coarse metric thread with Class 6g tolerance, shoulder diameter of 5mm (-0.025 to 0 mm tolerance), and shoulder length of 3mm (0 to 0.05 mm tolerance). Manufactured to exacting standards with Rockwell B79 hardness and 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substances.
