ABSTRACT:
A fluid actuated tool for securing together sheet metal parts comprising a power pack unit including a piston and cylinder assembly to which there is connected a jaw housing having a pair of complementary jaw members that are actuated between operative and inoperative positions by a ram connected to a piston reciprocally mounted in the cylinder of the power pack unit. The respective jaw members include complementary work engaging portions in the form of a piercing blade and complementary blade slot which function to pierce the metal parts and curl the displaced metal to positively secure the metal parts together. A valve is disposed in the power pack unit to control the flow of actuating fluid to and from the cylinder to effect the displacement of the piston to activate the jaw member, and a handle is connected to the power pack unit to facilitate the operation thereof.
