“Lockdowns” engine mount locking washers - quantity 4
"Lockdowns" engine mounting lock washers are a very high quality European-made 2-piece screw locking system, that uses a combination of serrated and cammed surfaces to keep screws from vibrating loose. These will work perfectly in applications like mounting engines to their mounts, or joining the top rails to a quick change motor mount, like the King Headz ones, where you don't want to use Loctite. These are a much higher quality, positive locking system than a cheap split lock washer. Includes directions on how to use.
