Check out these special washers!
These are the Nord-Lock wedge locking washers.
Sold in pairs and used in pairs. Used like a normal locking washer, placed under the nut or bolt head, they are designed to prevent loosening in critical applications or vibration situations. It’s all in the wedges! The pairs of washers cannot loosen until the wedges lift and by-pass. What this means is that they can be undone instantly with a socket or wrench on the nut but are highly resistant to loosening. And, unlike Nylon Lock Nuts they can be re-used.
