Professional Applications & Engineering Value

This M4 socket head cap screw delivers exceptional engineering value across industrial applications where space constraints and vibration resistance are critical concerns. The zinc-plated alloy steel construction provides reliable corrosion resistance for machinery, automotive components, and electrical enclosures exposed to harsh environments. The low-profile socket head with hex drive and pilot recess ensures positive engagement with standard tools, preventing stripping and enabling precise torque control in assembly operations. The partially threaded design concentrates thread engagement where needed most, while the Class 6g thread fit guarantees consistent mating with corresponding nuts and tapped holes. These metric socket screws are particularly valuable in precision equipment, jigs, and fixtures where high tensile strength and dimensional accuracy are paramount for long-term reliability.

Specification Summary & Compliance

This Class 8.8 socket head cap screw features M4 x 0.7mm coarse metric thread with Class 6g thread fit tolerance, ensuring precise engagement with standard components. The fastener maintains dimensional compliance with DIN 6912 manufacturing specifications for consistent quality and performance. Environmental compliance is verified through RoHS 3 (2015/863/EU) regulations, confirming the absence of restricted hazardous substances. The combination of 20mm overall length with 14mm minimum thread length provides optimal thread engagement while the 3mm hex drive size with pilot recess ensures compatibility with standard industrial tools.
