Customer Reviews (4.8 / 5 · 5 reviews)

Nicholas V. ★★★★★

Needed a massive batch of washers for a shelving project, and the zinc plating on these has held up perfectly against garage moisture. At .025" thick they're sturdy enough to prevent pull-through on my bolts without being bulky.

Thomas ★★★★★

These were just what I needed to finish mounting several shelves — the zinc plating looks clean and there wasn't a single rusty or bent washer in the bag.

Zoe ★★★★★

Needed a big batch of washers for a project, and these 5/16" flat ones fit the bill perfectly. The 0.025" thickness feels sturdy enough for general load distribution, and the zinc plating seems consistent across all 5000 pieces.
