Professional Applications & Engineering Value

Engineered for demanding industrial applications, these low profile socket head cap screws deliver exceptional value in machinery assembly, automotive components, and marine equipment where space constraints and corrosion resistance are critical. The 316 stainless steel material provides superior protection against chloride-induced stress corrosion cracking, making these metric socket head fasteners ideal for chemical processing, food manufacturing, and offshore installations. The partially threaded design ensures maximum clamping force distribution while the coarse thread metric configuration prevents cross-threading during high-speed assembly operations. These industrial fasteners maintain dimensional stability across temperature variations, offering reliable performance in both structural and precision engineering applications where vibration resistance and long-term durability are paramount.

Specification Summary & Compliance

This M8 x 1.25mm socket head cap screw features precise Class 6g thread fit tolerance ensuring secure mating with corresponding nuts and threaded holes. Manufacturing strictly adheres to DIN 7984 specifications for dimensional accuracy and mechanical properties. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits. With a minimum thread length of 22mm and overall length of 40mm, these screws provide consistent performance across industrial applications requiring metric coarse thread fasteners.
