Professional Applications & Engineering Value

This M8 metric socket head cap screw delivers critical advantages in applications where metal fasteners are unsuitable. The polypropylene plastic construction eliminates galvanic corrosion risks in electrical components and chemical processing equipment, while its off-white color provides visual contrast for quality control. The coarse 1.25mm pitch thread ensures rapid installation in plastic housings and soft materials, reducing assembly time. With its fully threaded design and DIN 912 compliance, this fastener maintains consistent clamping force in automotive trim, electronics enclosures, and food processing machinery where non-conductive, non-magnetic properties are essential.

Specification Summary & Compliance

This socket head cap screw features M8 x 1.25mm metric coarse threads with Class 6g tolerance for precise fit. Manufacturing follows DIN 912 specifications for dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. Additional certifications include UL 94 HB flammability rating for plastic materials.
