Professional Applications & Engineering Value

This M10 x 1.5 mm 316 Stainless Steel Hex Head Screw is engineered to solve critical challenges in industrial settings where corrosion and vibration are primary concerns. The DIN 6921 flanged design eliminates the need for a separate washer, providing a larger bearing surface that distributes clamp load effectively and prevents surface damage. Combined with the external hex drive and coarse metric thread, it ensures rapid installation and high resistance to loosening under dynamic loads. The partially threaded shank offers superior grip in tapped holes, making it ideal for machinery assembly, structural frameworks, and chemical processing equipment where durability and chemical resistance are non-negotiable.

Specification Summary & Compliance

This screw features an M10 metric coarse thread with a 1.5 mm pitch and Class 6g thread fit per ISO standards, ensuring precise dimensional accuracy. It is manufactured to meet DIN 6921 specifications for flanged hex head screws, with a length of 40 mm, flange diameter of 22.3 mm, and partial threading starting at 26 mm minimum thread length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial procurement.
