Bosses & Bungs
Threaded bosses for mounting anything to a frame. Twisted Choppers makes them in 5/16-18 and 3/8-16 threads, in thru-hole, blind-hole and counter-bore styles, from 1/2 x 3/4 up to 1 x 1 and 3/4 x 1-1/2 inch, so you can match the boss to the load and the tube it’s welded to. The 1-1/8-inch weld-on passenger peg mounts take standard 3/8-16 pegs. All machined in Sioux Falls from steel, not cast.
