1/2 x 2 擋泥板墊圈 | 鋼製三價鋅 (250個/包)

Bought these for some trailer repairs and the trivalent zinc finish holds up way better than the plain steel ones I've used before. The 250 count actually comes in handy when you're doing a whole project.

I needed these for a trailer project and the steel feels solid enough to handle heavy loads without bending. The trivalent zinc finish looks clean and should resist corrosion well.

The trivalent zinc finish is perfectly uniform across all 250 pieces, and I didn't have to toss a single one for burrs or uneven edges. They're solid and flat, which makes them ideal for spreading load on softer materials under a bolt.
