The Story
Six diameters, 680 pins, one organized 12-hole plastic drawer — the compact clear zinc option for shops that need the most-used cotter pin sizes on hand without the footprint of a full-size inventory. This kit covers 1/16" through 1/4" in a clean, clear plastic drawer that holds up in standard indoor shop environments.
What's Included
- Standard cotter pins in six diameters: 1/16", 3/32", 1/8", 5/32", 3/16", and 1/4"
- Multiple lengths per diameter — covers clevis, hitch pin, and shaft applications across the range
- 12-hole plastic drawer — QR-coded labeled and ready to stock
- 680 pieces total

Best For
- Agricultural equipment shops — tractors, implements, and balers use cotter pins at every hitch and linkage point, and the six-diameter range covers virtually all of them
- Outdoor power equipment dealers — mowers, tillers, chippers, and snow blowers that see frequent service
- Fleet and trailer maintenance — hitch pins, brake actuator clevis pins, and suspension links across multiple vehicle types
- Smaller shops and service counters — the 12-hole plastic drawer fits tighter workspaces and parts counters where a full-size 980-piece inventory isn't needed
- General repair and maintenance — a complete cotter pin stock in one bin without managing individual part numbers
About Cotter Pins
A cotter pin is a split fastener inserted through a drilled hole in a bolt, shaft, or clevis pin to prevent it from backing out or disengaging. Once bent open after insertion, it locks the assembly in place — simple, reliable, and used in nearly every piece of mechanical equipment.
Clear zinc is a chromate conversion coating applied over the zinc plating. It has a neutral silver appearance (no yellow tint) and provides solid corrosion protection for indoor shop environments, parts bins, and general mechanical use. For shop storage and everyday repair, it's a clean, professional-looking finish that's easy to read in a labeled bin.
This kit covers the same six standard diameters as our larger 980-piece assortment. If your shop goes through higher volumes or you need a heavier-duty metal drawer, see our 980-Piece Cotter Pin Assortment for the full-size zinc-plated version.
