Overview
The Klein Tools 6-Inch Impact Driver and Socket Extension Bar Set, 4-Piece (65038A) adds reach to your 3/8" and 1/2" drive impact tools. This is an impact socket extension set designed to provide greater access for sockets in hard-to-reach fastening applications. Klein model 65038A includes four 6" extension bars: two 3/8" square drive and two 1/2" square drive.
Why two of each size: you can stack two 6" bars when you need 12" of reach, or keep one in the bag and one on the tool. The extensions are impact-ready, built to withstand heavy-duty applications with impact drivers and impact wrenches.
A ball detent retention system holds sockets firmly in place, so a socket does not fall off the end of the extension in a deep recess. The knurled, textured shaft gives superior control when you spin a fastener by hand.
The bars are alloy steel with a black oxide finish. Each carries a high-visibility orange band and bold size markings for quick identification and to help prevent tool loss on jobsites.
Who should buy it: electricians, mechanical contractors, mechanics and maintenance techs who drive sockets with impact tools and regularly reach fasteners recessed behind equipment, framing or flanges.

Six inches of extra reach gets the socket down to fasteners an impact cannot get close to.
