McMaster 5823A3 Quick-Release Ratchet Wrench, Sealed Head, 1/2" Square Drive, 10.5" Long, Chrome-Plated Steel

Built for tough industrial conditions, these wrenches have a gasket that seals lubrication in and keeps dirt, dust, and moisture out to protect the ratchet mechanism. When it's time to release the socket, just push the button on the back of the wrench head. These wrenches have a ratchet mechanism that allows you to turn fasteners without removing and repositioning the tool. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.

Chrome-Plated Steel — Chrome-plated wrenches are shiny and corrosion resistant. They have a smooth surface, so they're easier to clean than black-oxide wrenches.
