Claire C. ★★★★★

Works perfectly to keep those #10 socket head cap screws from backing out during milling. The spring steel has just the right amount of bite without distorting the threads.

Joseph ★★★★★

The inside diameter is exactly 0.200 as stated, so my #10 screws fit snugly without any wobble. It’s a simple, effective lock washer that does exactly what it should for my bench top setup.

Avery ★★★★★

Used a few of these with #10 socket head cap screws on a new machining fixture and the hold is solid—no loosening after vibration. The steel feels sturdy, and they fit perfectly without any fuss.
