Professional Applications & Engineering Value

This M8 socket head cap screw is engineered to address critical challenges in industrial and mechanical applications where high tensile strength and corrosion resistance are paramount. Made from black-oxide alloy steel, it combats rust and wear in harsh environments, such as automotive assemblies, heavy machinery, and construction equipment. The coarse metric thread (1.25mm pitch) and Class 5g6g thread fit ensure easy, precise installation, reducing assembly time and preventing cross-threading. With a partially threaded design and 180mm length, it offers flexibility for clamping and alignment tasks, while the hex socket drive enables high-torque tightening in confined spaces. Ideal for engineers and procurement specialists, this screw delivers reliable performance, minimizes maintenance, and supports efficient production workflows by meeting rigorous DIN 912/ISO 4762 standards.

Specification Summary & Compliance

This product adheres to precise dimensional and performance criteria, including a Class 5g6g thread fit for consistent engagement and a coarse M8 x 1.25mm thread per metric standards. It conforms to DIN 912 and ISO 4762 specifications for socket head cap screws, ensuring interchangeability and quality. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming adherence to environmental and safety regulations without hazardous substances.
