Midwest Fastener 1/2-13 Grade 8 Hex Flange Lock Nut

The Midwest Fastener 1/2-13 Grade 8 Hex Flange Lock Nut is engineered for demanding fastening applications where high tensile strength and resistance to loosening are essential. Constructed from Grade 8 steel, this lock nut delivers superior holding power in heavy machinery, automotive repairs, and agricultural equipment. Featuring an integrated wide flange base, this nut distributes clamping pressure over a larger surface area to eliminate the need for a separate washer while preventing damage to mating components. The protective yellow zinc plating offers enhanced resistance against rust and corrosion in tough environments.
