Professional Applications & Engineering Value

This M8 flanged button head screw is engineered to address critical challenges in demanding industrial settings. Constructed from 316 Stainless Steel, it offers exceptional resistance to corrosion from chemicals, saltwater, and extreme weather, making it ideal for marine, chemical processing, and outdoor equipment. The flanged design eliminates the need for a separate washer, distributing clamp load over a wider area to prevent surface damage and resist loosening under vibration. Combined with a Class 6g coarse thread and fully threaded shank, it ensures rapid, secure fastening in high-stress assemblies, from machinery frames to structural supports, reducing maintenance and enhancing operational reliability.

Specification Summary & Compliance

This screw features an M8 x 1.25mm coarse thread with a Class 6g tolerance per metric standards, ensuring precise fit and interchangeability. Dimensions include a 20mm length, 5.2mm head height, and 21.4mm flange diameter. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming adherence to environmental and safety regulations for industrial use.
