heavy profile Steel Insert locknuts for extreme vibration

These withstand bigger loads by spreading them over a wider area and are about 10% taller and wider than conventional steel-insert locknuts. Of all the heavy-profile locknuts we sell, they also have the most secure grip. Even when there is a lot of vibration, the tab on the insert prevents the nut from turning. These locknuts are perfect for machinery like compactors, shakers, and conveyors that move constantly or have abrupt starts and pauses. They are actually used to secure parts of roller coasters since they are so safe. Although these locknuts can be reused, you should use a new nut for the strongest grip because they lose some of their holding power after the first use.
