Klein Tools 660KIT2 – Frequently Asked Questions

1) What sizes are covered in the Klein Tools 660KIT2 6-in-1 impact socket set?
The 660KIT2 covers twelve hex sizes across six slotted sockets: 1-1/8 x 15/16, 1 x 13/16, 7/8 x 11/16, 3/4 x 9/16, 5/8 x 7/16, and 1/2 x 3/8 inch. Alongside those it carries the 6-in-1 square impact socket with 3/4, 13/16, 1 and 1-1/8 inch square drives, plus a 7/16 inch hex quick-change adapter. Eight pieces total.
2) Can I run the Klein 660KIT2 sockets on an impact wrench, or are they hand-tool only?
They are impact rated, so they are built to run on an impact wrench rather than being chrome hand sockets. Steel construction, and the set is made to ASME B107.2. Eye protection is called for whenever you are driving them.
3) Does the Klein 660KIT2 handle pole line hardware and square nuts on utility poles?
That is the job it is built for. The NRHD4 6-in-1 square socket drives 3/4, 13/16, 1 and 1-1/8 inch square nuts, and it has an alignment slot so you can tighten and loosen most pole hardware where a bolt or rod runs through the nut. The 66090 slotted sockets are 12-point and also slotted, so they pass over protruding thread.
4) What is the 7/16 inch hex adapter in the Klein 660KIT2 for?
The 7/16 inch hex quick-change adapter lets the square sockets run off a 7/16 inch hex drive, which is the shank most cordless impact drivers used by linemen and utility crews take. It is what ties the 6-in-1 square socket (Cat. No. NRHD4) to an impact driver instead of a 1/2 inch square drive.
5) How does a 2-in-1 slotted socket switch between its two sizes?
Each of the six sockets in the 66090 set is single ended with two coaxial spring loaded sockets stacked inside it. Push it onto the smaller nut and the inner socket engages; press it on a larger nut and the outer one takes over. No pulling a collar or flipping the socket, which matters when one hand is on the ladder.
6) Which Klein catalog numbers make up the 660KIT2 if I need to reorder a piece?
The 660KIT2 bundles two Klein items: the NRHD4 6-in-1 square impact socket and the 66090 2-in-1 slotted impact socket set, 12-point, 6-piece. If you lose or wear one part of the kit, those are the two catalog numbers to order against.
7) How big and heavy is the Klein 660KIT2 kit for a truck bin or tool bag?
The kit runs 11.19 inches high, 7.06 inches wide and 6.94 inches long, and weighs 6.1 pounds. That is a compact block for a gang box drawer or a bucket truck bin given it replaces twelve hex sizes and four square sizes.
