Eli X. ★★★★★

The M5 sizing is spot-on for my mill table clamps, and it holds tension firmly without deforming under load. I grabbed a few packs for my bench projects and they seat flush every time. Solid little washers for the price.

James ★★★★★

I’ve been using these to secure the M5 bolts on my bench top jig, and they sit flat without any wobble during cuts. The size is consistent across the bag, which saves me from digging through mismatched hardware. Exactly what I needed for quick, solid fastening.

Thomas P. ★★★★★

Used these M5 lock washers on my mill's clamping kit and they held fast through several hours of heavy cutting. The 6.2mm inner diameter fits the bolts perfectly without any slop.
