SLOT ROUND NUT NYLOK GUK 15MM X 1.O Y/P

A slot round nyloc nut combines the smooth, circular body of a round or slotted nut with a nylon insert for vibration resistance. It features external spanner slots or holes for tightening with a hook wrench and an internal nylon ring that provides frictional locking on the bolt threads. This dual design offers both precision and security in applications where space is limited and vibration is present.
