The HP-2 hand riveter from Marson is rugged and reliable. This hand plier riveter includes 4 nose pieces for 3/32 , 1/8 , 5/32 and 3/16 rivets. This riveter is the single most popular model sold anywhere. A square shoulder fulcrum pin made of cold-formed heat treated steel eliminates pin rotation that can elongate the engaging holes and cause premature tool failure in imitation tools. 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.
