William ★★★★★

Needed to replace a bunch of worn-out washers on an old trailer, and these .187" thick ones handled the heavy load without deforming at all. The steel construction feels solid, and the 200-pack gave me plenty to finish the job with spares left over.

William V. ★★★★★

I was pleasantly surprised by the thickness—.187 inches is no joke, these washers really lock down bolts without deforming. Knocked out a quick shelf install and they distributed the load perfectly over the wood surface. No skimping on the steel here, these feel solid in the hand.

Scarlett ★★★★★

The load-spreading on these is exactly what I needed for heavy framing work—that .187-inch thickness really does the job. Bought the 200-pack and they arrived true to size, no warped edges or rough burrs to fight with.
