An edge clamp apparatus includes an elongated body 14 defining a cylindrical bore within which a piston 86 is received for movement between retracted and extended positions. The body 14 includes a mounting surface 18 and opposed front and rear body portions, and the bore is formed in the rear portion. The front portion includes a support surface 48 that intersects the cylindrical bore of the rear portion and is inclined relative to the mounting surface by an angle of about 10 DEG . A cap 16 is secured to the front portion of the body 14 for closing off the cylindrical bore of the body and limiting movement of the piston 86. The cap 16 includes an inner surface engaging the support surface 46 of the body 14, and a recess formed in the inner surface for receiving a clamp blade 12. The blade is supported on the support surface of the body within the recess of the cap 16 for movement between a retracted, releasing position and an extended engaging position, and includes a rear portion 70 defining a central longitudinal axis and extending into the cylindrical bore for engagement with the piston, and an opposed front portion 76 presenting a clamp head that is offset from the longitudinal axis such that the head is spaced from the support surface 46 of the body 14.
