External Grip Extractors

External grip extractors are sockets that remove rounded nuts and bolt heads. Fitted over the damaged fastener, the internal profile bites into the remaining metal as torque is applied, so a nut with no corners left, a lug nut with a chewed wheel lock, or a rusted stud still comes out on a ratchet or impact wrench. Metric and SAE sizes for 1/4 in, 3/8 in and 1/2 in square drive, in Standard and Deep lengths, individually or in sets with an aluminium rail. Pusher rods push the fastener back out of the extractor afterwards.
