• High tensile strength of 110,000 psi ensures reliable, secure fastening under heavy loads and vibrations
• Precise Class 6g thread fit for smooth installation and consistent performance in metric assemblies
• Low-profile socket head design saves space and allows for flush mounting in compact applications
• Hex with pilot recess drive provides anti-cam-out engagement for efficient torque transfer and reduced tool slippage
• Partially threaded shank offers unthreaded grip length for improved alignment and shear resistance
• Compliance with DIN 6912 and RoHS 3 guarantees quality, safety, and environmental standards for global industrial use

Professional Applications & Engineering Value

This M4 socket head cap screw is engineered from Class 8.8 alloy steel with a zinc-plated finish to combat corrosion in demanding settings like machinery, automotive, and structural frameworks. The partially threaded design and coarse 0.7mm pitch enable quick assembly and robust clamping force, reducing the risk of loosening under dynamic stresses. Its low-profile head and 3mm hex with pilot recess drive ensure easy access in tight spaces, while the Rockwell C20 hardness and 110,000 psi tensile strength provide durability for high-stress applications, minimizing maintenance and downtime.

Specification Summary & Compliance

This fastener adheres to DIN 6912 standards with a Class 6g thread fit for precise metric tolerances. It features a right-hand thread, M4 x 0.7mm coarse pitch, and 16mm length with a minimum thread length of 12.5mm. Compliant with RoHS 3 (2015/863/EU), it meets environmental and safety regulations for industrial use, ensuring reliability and consistency in professional assemblies.
