Customer Reviews (4.6 / 5 · 5 reviews)

Nicholas ★★★★★

These lock washers held tight on a trailer hitch I rebuilt — no loosening after a hundred miles of rough road. The 1000-pack covers multiple jobs without needing to reorder.

Samuel W. ★★★★★

Installing these on a heavy-duty trailer hitch, I was happy the 1000-count bag allowed me to sort out a few imperfect ones and still have plenty left. The mil-spec rating gives confidence they’ll hold up under real road vibration.

Harper ★★★★★

Put a whole bag of these to use rebuilding a trailer hitch, and not a single one has backed off even on rough gravel roads. The 1000-count package is great for larger projects where you don't want to run out mid-job.
