Klein Tools' Slim-Profile Mini Ratchet Set is the perfect answer for fastening in small, tight spaces. The 72-tooth, low-profile gear head only needs 5-Degrees of sweep allowing professionals to fasten in spots other drivers just won't fit. The handle is designed with a finger loop for control and convenience and is made of high-strength Chromium-Vanadium steel for increased torque and long tool life. The 1/4-Inch dual-drive head has integrated 5/16 and 1/4-Inch nut drivers. This set also comes with a versatile set of bits including #1 and #2 Phillips driver bits, 3/16 and 1/4-Inch slotted driver bits, and a 1/4-Inch drive socket adapter. So, there's no need to go back to the toolbox.
