Lightweight and compactly designed, the 3/8 in. Drive Crowfoot Wrench Set is ideal to have on hand for reaching restricted or hard-to-access fastening jobs. The arched surfaces of these wrenches distribute force over a larger area to reduce corner loads and prevent fastener rounding. With the Anti-Slip Design (ASD), these wrenches offer an extra-firm grip as well as corrosion prevention, thanks to its full-polish finish. Sizes 1 in. and larger include a convenient locking hole for use with locking extensions.
