Klein Tools 647 Tool Set, Made in USA, Nut Drivers Sizes 3/16, 1/4, 5/16, 11/32, 3/8, 7/16, 1/2-Inch, Chrome-Plated 6-Inch Shafts, Cushion Grip, 7-Piece

Works great on hard to reach parts of heating and air systems.

Perfect length to reach blind nuts on aircraft lights. Between the magnetic nut holder and a RD4, make sure a job easy.

It is very good product and strength.

This set is well made and cushioned quite nicely. I got the set as a warehouse deal and they arrived in perfect shape. My only warning to you is to make sure you won't need a longer screwdriver or a larger selection of sizes before you purchase this set. Since I've had them, there are several times I wished I had an extra few inches in length (insert pun here) and some of the in-between sizes. I work on all types of machinery and electrical equipment, from kids toys to heavy duty industrial machines, and the only time a klein product has disappointed me is when I bought the non contact voltage tester.

Kit muito bom

Accurate description. Great length with limited girth

Excellent product

Klein are the finest tools made, and I use 30 to 40 Klein Items in both my Electrical Business, as well as a Second Set for strictly home use. They are worth the extra cost given most are Made In America, which is priceless in my mind. Guaranteed for life and far / far superior to Craftsman Tools. Craftsman was a quality brand, but the quality has deteriorated rapidly since Sears got into financial difficulty 5 years ago. Try Klein Tools and you will never buy another brand.
