These hand retractable plungers are used for positioning, locating and fastening, without the use of tools, in a wide range of applications. As the handle is turned 180 degrees on the cam of the body, the plunger is retracted into the housing. There is a groove on the top of the cam that locks the plunger into the retracted position. They are made from steel and have a ground and hardened plunger. The body and plunger have a black oxide finish and the handle has a powder coated finish.
