Professional Applications & Engineering Value
This precision shoulder screw with nylon patch locking technology addresses critical vibration-induced loosening challenges in industrial machinery and precision equipment. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining 70,000 psi tensile strength for demanding applications. The precisely controlled shoulder diameter and length tolerances ensure accurate component alignment in assemblies requiring precise axial positioning. The Class 6g thread fit guarantees consistent engagement in metric fastening systems, while the permanent nylon locking patch maintains clamp force integrity across a wide temperature range from -70° to 250°F. Ideal for robotics, automation equipment, precision instruments, and machinery where vibration resistance and positional accuracy are critical.
Specification Summary & Compliance
This M4 shoulder screw features Class 6g thread tolerance with M4x0.7mm coarse metric threading and precise shoulder fit with diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm. Manufactured to industry standards with hex drive socket head configuration and passivated finish. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use in global industrial markets.
