Key Features
Overview
The Klein Tools KNECT Quad-4 Heavy-Duty Impact Flip Socket, SAE, 2-Piece (6513QS) combines four large SAE sizes in one socket. This is a heavy-duty impact flip socket designed for driving 3/4", 13/16", 7/8" and 1" fasteners, sizes that come up constantly on utility, structural and equipment hardware.
Access 3/4" and 7/8" on one end, then flip to use 13/16" and 1". The smaller socket of each pair is spring-loaded and compresses out of the way under pressure, so the larger hex engages without swapping sockets.
A multi-purpose adapter is included for Klein's KNECT (M) system, so the socket can run on a KNECT pass-through socket wrench or screwdriver as well as an impact. Use the impact where you have room and the pass-through wrench where you need to work down a long threaded rod.
The 3/8" drive socket is heat-treated cold forged steel with a manganese phosphate finish and a deep well that reaches over extended threads. Industry-standard painted color rings mark each size. It measures about 1-3/8" (3.5 cm) across and 4-1/2" (11.4 cm) tall.
Who should buy it: linemen, utility crews, mechanical contractors and anyone who reaches for 3/4" through 1" sockets daily.
