M8-1.25 Class 10 Flange Nuts
This pack contains fifteen zinc-plated steel flange nuts with an M8 thread and 1.25 mm pitch. The integrated flange acts as a built-in washer to spread clamping force across the joint. Class 10 rating suits high-strength fastening in automotive and industrial assemblies.
Replaces separate nut-and-washer stacks
The flange eliminates the need for a flat washer, reducing part count and assembly time. The step up is worth it when vibration or uneven surfaces risk loosening a standard hex nut. Not for joints that require a lock washer or prevailing-torque feature.
Hand-threads onto M8-1.25 studs
Standard metric tools drive the hex without special sockets. Zinc plating resists corrosion but is not a substitute for stainless steel in marine or chemical exposure. Ensure the mating threads are clean and undamaged to achieve full Class 10 preload.
