Midwest Fasteners Zinc Plated Steel Quick-Release Round Wire Lock Pin

Midwest Fasteners Zinc Plated Steel Quick-Release Round Wire Lock Pin

Midwest Fasteners offers this round wire lock pin, machined from steel and finished in zinc plating for corrosion resistance, available across a size range from 1/4" x 1-3/8" up to 3/8" x 1-5/8" to match different bore and shaft combinations, including 1/4" x 2-1/2", 3/8" x 1-1/2", 3/8" x 1-3/8", 5/16" x 2-1/2", 5/16" x 2-1/4", and 5/16" x 1-3/8". This wire lock pin is built for quick-release retention on pins, shafts, and clevis-style connections where a spring-tensioned pin is needed instead of a cotter pin or bolted connection. Every size shares the same zinc plated steel construction, so confirm the bore and shaft diameter for your application before selecting a size.
