Review: 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.
Review: and these nut drivers are great. I bought these for an old - Klein tools have remained my tools of choice for 40+ years, and these nut drivers are great. I bought these for an old, retired man's hobby of replacing the webbing on aluminum lawn chairs, and I should have bought the shorter shaft nut drivers. But, I'm keeping these, they work great, and I'm looking for a chance to use them where I need long shafts!
