Midwest Fasteners Class 8 Yellow Zinc Fine Thread Finished Hex Nut

Midwest Fasteners Class 8 Yellow Zinc Fine Thread Finished Hex Nut

The Midwest Fasteners Class 8 Yellow Zinc Fine Thread Finished Hex Nut is a six-sided steel hex nut built to Class 8 strength standards and finished in yellow zinc for corrosion resistance and a consistent gold appearance. This family is available in metric fine-thread sizes spanning 10mm-1.25 through 12mm-1.5, so the same Class 8 strength, fine thread connection, and yellow zinc finish carry across the entire size range. It is designed to mate with fine-thread bolts, studs, and cap screws rather than standard coarse-thread hardware, making it a dependable choice for machinery assembly, equipment repair, and other mechanical connections where fine-thread fasteners are already specified.
