Professional Applications & Engineering Value
This M4 shoulder screw delivers exceptional engineering value in precision assembly applications where component alignment and vibration resistance are critical. The alloy steel construction with black oxide finish provides superior protection against corrosion while maintaining the high tensile strength required for demanding mechanical systems. The 10mm shoulder length with precise tolerances ensures accurate positioning of moving parts in machinery, automotive assemblies, and industrial equipment. The hex socket drive with knurled head design allows for secure tool engagement, preventing slippage during installation in confined spaces. These metric shoulder screws are engineered to solve common industrial challenges including misalignment issues, thread stripping, and premature fastener failure.
Specification Summary & Compliance
This precision shoulder screw features M4 x 0.7mm coarse metric threading with Class 6g thread fit for optimal engagement. Critical dimensions include shoulder diameter of 5mm with tolerance of -0.072 to -0.01 mm and shoulder length of 10mm with tolerance of 0 to 0.25 mm. The fastener meets international standards for metric fasteners and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance compliance.
