Professional Applications & Engineering Value

These M4 socket head cap screws deliver critical engineering solutions where space optimization and structural integrity are paramount. The black-oxide alloy steel construction combined with ultra-low profile head design addresses common challenges in compact machinery, precision equipment, and automated systems where clearance limitations exist. The Class 5g6g thread fit provides exceptional dimensional stability, preventing loosening under vibration while maintaining precise alignment in metric coarse thread applications. With 140,000 psi tensile strength, these fully threaded fasteners ensure reliable performance in high-stress industrial assemblies, from manufacturing jigs to transportation equipment, where consistent clamping force and durability are essential for operational safety and maintenance reduction.

Specification Summary & Compliance

Manufactured to precise metric dimensions with M4 x 0.7mm coarse thread and 14mm length (±0.127mm tolerance). Threads conform to Class 5g6g precision standards for consistent fit and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black-oxide surface treatment on alloy steel provides corrosion resistance while maintaining the material's inherent strength characteristics.
