HEAVY THIN NYLON INSERT LOCK NUTS
About half the height and 10% wider than standard nylon-insert locknuts, these locknuts are often referred to as thin heavy locknuts. Use them in low-clearance applications or jam one against a heavy hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.
