A handy tool to have when hand tightening or lossening is necessary. No ratcheting action. It can attach to a 1/2" ratchet to add the thumbwheel function. It has good knurled grip to prevent slipping. Plus it has a 1/2" female port to attach a breaker bar or anything else which uses a 1/2" drive anvil. Solid Snap-On quality! Made in the USA.๐
