Professional Applications & Engineering Value

Engineered for demanding environments, this M10 hex head screw delivers critical performance in machinery, structural frameworks, and heavy equipment assemblies. The Class 8.8 steel construction and coarse metric thread provide superior clamping force and vibration resistance, addressing common failure points in dynamic loads. The zinc-plated finish combats oxidation and chemical exposure, making it ideal for outdoor, automotive, or manufacturing settings where corrosion can compromise safety. With a partially threaded shank, it ensures precise load-bearing on the unthreaded portion, reducing stress concentration and enhancing fatigue life. Fully compliant with ISO 4014, it guarantees dimensional accuracy and seamless integration into global supply chains, supporting efficient B2B procurement and project timelines.

Specification Summary & Compliance

This fastener adheres to ISO 4014 specifications (equivalent to DIN 931) with a Class 6h thread fit for precise metric threading. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory alignment. The Class 8.8 strength grade corresponds to a tensile strength of 110,000 psi and Rockwell C21 hardness, validated for industrial use. Dimensions include M10 x 1.5 mm coarse thread, 95 mm length, and 26 mm minimum thread length, manufactured under strict quality controls for reliability in B2B applications.
