Midwest Fasteners Class 10 Zinc-Plated Steel Metric JIS Flange Hex Nut

Midwest Fasteners Class 10 Zinc-Plated Steel Metric JIS Flange Hex Nut

Midwest Fasteners' Class 10 zinc-plated steel JIS flange nut is available with Nut Size selectable from 6mm-1.0 through 8mm-1.25 up to 10mm-1.25, covering the common metric pitches found on import vehicles, motorcycles, small engines and other metric-spec equipment. Built to the Japanese Industrial Standard flange nut profile, the integral flange on every size seats directly against the mating surface and spreads clamp load without a separate washer, speeding assembly and helping joints stay tight under vibration. Class 10 steel construction delivers the strength needed for structural and drivetrain-adjacent connections where a standard hex nut would be undersized, and the zinc finish applied across the family adds a layer of corrosion resistance for parts exposed to moisture, road spray and shop environments. Each option ships as a hex nut with the JIS flange geometry built in, making this family a practical match for OEM and aftermarket metric hardware.

Key Features

• Size Range: Nut Size selectable from 6mm-1.0 through 8mm-1.25 up to 10mm-1.25 metric thread.
• Material & Finish: Steel construction with a Zinc finish for improved corrosion resistance over bare steel, consistent across every size in the family.
• Type: JIS flange nut design with an integral flange that distributes bearing load and reduces the need for a separate washer.
• Grade: Class 10 steel, a higher-strength class suited to demanding clamp-load applications regardless of the size selected.
• Country of Origin: Manufactured in China.
