- High-strength performance delivering 70,000 psi tensile strength and Rockwell B79 hardness for demanding applications
- Secure hex drive engagement with 2.5mm socket head preventing cam-out and ensuring reliable torque transmission
- Accurate thread fit with Class 6g metric coarse threads providing consistent fastening and vibration resistance
- Compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries
- Smooth head profile allowing flush mounting and reducing snagging in precision assemblies
Professional Applications & Engineering Value
This M4 shoulder screw delivers critical engineering value in applications requiring precise shaft positioning and rotational control. Manufactured from 316 stainless steel with a passivated finish, it solves corrosion-related failure points in chemical processing, marine, and food equipment where moisture resistance is paramount. The 5mm shoulder length with precise diameter control acts as a built-in spacer, eliminating misalignment in machinery assemblies, pivots, and bearing mounts. The socket head hex drive ensures high torque capability in confined spaces, while the Class 6g thread fit maintains clamping force under vibration. These features make it ideal for precision industrial applications demanding dimensional stability and long-term reliability.
Specification Summary & Compliance
This metric shoulder screw features M4 x 0.7mm coarse threads with Class 6g thread fit per ISO standards. Shoulder dimensions include 5mm diameter with -0.025 to 0 mm tolerance and 5mm length with 0 to 0.05 mm tolerance for precise fitment. Mechanical properties include 70,000 psi tensile strength and Rockwell B79 hardness. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
