Aircraft Tool Supply 3581-6 Hi-Lok Removal Socket (3/16")

These patented specialized sockets are the ultimate for removing stubborn Hi-Lok¨ & Hi-Lite¨ fasteners. Using a left-handed thread and a tapered bore, these hardened chromium-alloy removal tools bite into and firmly grip the aluminum fastener for easy removal. They are as easy to use as a conventional socketÉyou simply place the socket over the collarÉand rotate! Patented sockets literally "Thread & Lock" onto the collar for simple removal, while other more expensive Hi-Lok & Hi-Lite style removal sockets currently on the market attempt removal by actually "cutting" the collar in some way, leaving dangerous FOD (ForeignÊObject Debris) behind.
