This kit includes 3/16" & 1/4" Magna-Grip noses used to install cab body panels and a 3/16" C6 nose used to install chrome grill bolts. Plus, this kit includes a 3/16" - 1/4" Magna-Lok blind fastener nose as used for sleeper conversions. It is compatible with Huck 202, 210, 212, 244, 2025, 229, 230, Gage Bilt 722, 730, 731 and all RAT brand lockbolt tools. These nose measures 2" long and is 3/4" in diameter. These imported noses have several quality features including, tool steel anvils and chrome molly-jaws hardened to Rockwell C60. The anvils have a black anodized finish and a laser engraved picture on each nose of the intended fastener to help users with nose selection. The independent jaw design keeps costs lower compared to unitized jaw model types. These noses have performed as well as most major USA made brands because the maker also manufactures lock bolt fasteners and they build noses very well.
