Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M8 flanged hex head screws provide exceptional engineering value through their 18-8 stainless steel composition and DIN 6921 compliant design. The integrated flange eliminates washer requirements while distributing clamp load over a wider surface area, preventing surface damage and maintaining joint integrity. The coarse thread pitch (1.25mm) ensures rapid installation and superior resistance to vibration loosening in heavy machinery, automotive assemblies, and structural frameworks. With full threading along the entire 40mm length, these fasteners accommodate varying material thicknesses while the external hex drive allows for high-torque installation using standard tools. The combination of 100,000 psi tensile strength and corrosion-resistant properties makes these metric screws ideal for applications where reliability and durability are critical in challenging operating conditions.

Specification Summary & Compliance

This M8 x 1.25 x 40mm flanged hex head screw features precision Class 6g thread fit according to metric standards, ensuring consistent dimensional accuracy and reliable performance. The fastener is manufactured to meet DIN 6921 specifications for dimensional and mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and material restrictions adherence, making these screws suitable for global industrial applications requiring certified components.
