Snap-on not only offers the widest range of 1/2 drive tools in the industry, we build them to last - using cold-formed alloy steel in most of them. Then, we put them through rigorous testing under extreme conditions, to assure they’ll stand up to the most demanding usage. They’re built to perform, too, with Dual 80® Technology that provides dual pawls and an 80-tooth gear for more ratcheting power in less lateral space. Our sockets also feature Flank Drive® for added turning power and less slippage. Plus grooved detents for stronger attachment to the ratchet and easier engagement in any position.
