Professional Applications & Engineering Value
This M6 socket head cap screw delivers critical engineering solutions where high tensile strength and precision threading are paramount. The black-oxide alloy steel construction provides superior protection against corrosion in demanding environments like manufacturing equipment, automotive assemblies, and heavy machinery. The fine thread pitch (0.75mm) ensures maximum thread engagement in hardened materials, reducing the risk of vibration-induced loosening while the partially threaded design offers flexibility for applications requiring both clamping and sliding functions. With its 5mm hex drive and standardized socket head profile, installation torque is efficiently transferred without cam-out, making these metric hex socket screws ideal for space-constrained applications requiring reliable, high-strength fastening solutions.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 21269 specifications with Class 5g6g thread fit tolerance ensuring precise dimensional accuracy. The 40mm length with 24mm minimum thread length provides optimal engagement characteristics. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming these industrial fasteners meet the latest international safety and sustainability standards for professional use.
