Midwest Fasteners Class 8 Zinc Plated Steel Metric JIS Hex Nuts

Midwest Fasteners Class 8 Zinc Plated Steel Metric JIS Hex Nuts

Midwest Fasteners Class 8 Zinc Plated Steel Metric JIS Hex Nuts are manufactured to the Japanese Industrial Standard (JIS) hex nut profile, a dimensional standard with a different width-across-flats and thickness than ANSI or DIN hex nuts. This family is available in 8mm-1.25, 10mm-1.25, and 12mm-1.25 metric thread sizes, letting technicians and fabricators match the exact JIS-spec bolt, stud, or threaded rod on equipment, machinery, or vehicles originally built to JIS specifications where standard hex nuts will not seat or thread correctly. Every size in the family is manufactured from Class 8 zinc plated steel, giving it higher load capacity than a standard-grade nut along with added corrosion resistance for general industrial and mechanical use.

Key Features
