This compact ratchet handle works with any standard 1/4" square drive socket (sold separately). The orange-and-black plastic handle offers great comfort and ergonomics. The unique reversing mechanism snaps positively from side to side. No more mistakenly reversing the ratchet by bumping a little lever! Even if you hold the head of this ratchet in the palm of your hand, you will not accidentally switch it. Fine 48-tooth ratchet requires just 7.5 degrees of rotation.
