A fastener driving tool with a working cylinder and a piston, the piston outer surface having a lubricant-saturated foam material that stores and dispenses lubricant into the piston-cylinder wall interface, thereby increasing the performance and lifespan of the tool. Another embodiment discloses a two-part piston in which the bottom portion is made of metal and absorbs the main mechanical loading forces of the piston drive and return strokes, and the top portion is made of a non-metallic material that has surfaces that act as sliding bearings against the inner wall of the cylinder.

A fastener driving tool with a hanger attachment that is rotatable around the handle of the tool. The hanger is configured to fit a 2×4 rafter or joist on either side of the tool. The rotatable hanger allows for this flexibility in hanging the tool securely on a jobsite. The hanger has a plurality of designed stop positions (detents) around the handle. A user rotating the hanger around the handle will feel the hanger become more secure at one of these designed stop (detent) positions.
