he HP-2 is the largest selling hand rivet tool in the industry. Known and trusted for durability, quality and performance, the HP-2 is often copied but never equaled. It's square shoulder fulcrum pin of cold-formed heat treated steel prevents pin rotation that can elongate the engaging holes and cause premature tool failure in imitation tools. Other quality features include: precision die cast, high strength aluminum alloy body; drop forged carbon steel upper handle; and thick cushion-molded vinyl grips for comfort. The HP-2 sets up to 3/16"" steel rivets and comes with four mounted nosepieces (3/32"", 1/8"", 5/32"", and 3/16"") and a service wrench.
