Midwest Fasteners Class 8 Zinc Plated Coarse Thread Hex Nut

Midwest Fasteners Class 8 Zinc Plated Coarse Thread Hex Nut

The Midwest Fasteners Class 8 Zinc Plated Coarse Thread Hex Nut is a steel hex nut finished in zinc for corrosion resistance and a clean, consistent appearance on the jobsite or in the shop. This family is available in coarse-thread metric sizes ranging from 3mm-.50 up to 20mm-2.50, covering 3mm-.50, 7mm-1.00, 10mm-1.50, 12mm-1.75, 14mm-2.00, 16mm-2.00, 18mm-2.50, and 20mm-2.50, so contractors and fabricators can match the correct nut to the bolt or cap screw on hand. Every size shares the same Class 8 strength rating, steel construction, and zinc finish, giving the whole family consistent performance and appearance whether you need a small 3mm nut for light assembly or a larger 20mm nut for heavier-duty fastening. Coarse thread across the range means fast, forgiving engagement and resistance to cross-threading and stripping during installation.
