Auto mechanics, in particular, work in a lot of tight spaces, so they often reach for their Performance Tool quick-release flex-head teardrop ratchets. They`re made of chrome vanadium alloy steel for strength and durability, with a polished nickel chrome plated finish to resist corrosion. The quick-release feature lets you change socket sizes with ease, and the flexible head often provides that extra edge to tighten or loosen stubborn nuts and bolts.
