Bought 100 for Shop Stock – Excellent Value

At 75% off, this is a steal. We go through these fast during brake and hub jobs. Zinc coating holds up better than plain steel.

Durable and Corrosion-Resistant

So far, best cotter pins I’ve found online. Zinc finish is smooth and even. No pitting or flaking, even after washdowns.

Zinc Plating Makes a Difference

I'm in a snowy climate with road salt. After two months, no rust—unlike the black oxide pins I used before. Definitely worth it.

Reliable and Consistently Made

Used a dozen on various trailers. All fit 1/8" holes exactly. No burrs or misshapen legs. Good for both temporary and permanent use.

Perfect Fit for Hub Nut Locking

Used these on my trailer hub castle nuts. The 1/8" x 1-3/4" size is spot-on. Zinc plating resists rust even after rain and road spray.
