Klein 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 deg of sweep allowing professionals to fasten in spots other drivers just won't fit. 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 in dual-drive head has integrated 5/16 and 1/4 in nutdrivers. This set also comes with a versatile set of bits including #1 and #2 Phillips driver bits, 3/16 and 1/4 in slotted driver bits and an 1/4 in drive socket adapter. So, there's no need to go back to the toolbox.
