Midwest Fastener 8 mm - 1.00 Zinc Castle Nut

The Midwest Fastener 8 mm - 1.00 Zinc Castle Nut is engineered for dependable locking performance in high-vibration applications. Designed with slotted notches along the top rim, this nut allows a cotter pin or wire to pass through a drilled bolt shank, preventing accidental loosening under intense dynamic loads. Constructed from durable Grade 8 steel and finished with a protective zinc coating, this castle nut offers excellent tensile strength and corrosion resistance. It is well-suited for steering linkages, wheel hubs, suspension components, and agricultural or industrial equipment where fastener retention is essential for safe operation.
