TC Bros. Counterbored Mounting Bungs

Save time and create super-strong mount points for just about anything on your bike using these counterbored bungs that yield a finished appearance when combined with the appropriate socket head fastener.

Bungs are American-made 1018 mild steel that's a breeze to weld
CNC-machined for symmetry and accuracy
Counterbored end for a clean, custom look saves time at the lathe
Accepts most common socket head hardware with threads of the nominal diameter listed, fine or coarse
Corresponding fastener not included
3/4" OD
Bungs are sold as a set of 4

Bungs are counterbored to fit standard socket head bolts so that the head of the bolt is flush inside the bung for a clean-looking installation. Pair these with any of our matching threaded bungs for a professional-looking, high quality mounting solution.

Save fabrication time with these rugged, reliable bungs from TC Bros. We offer these because we need them when we build motorcycles, so we're pretty sure you'll find them handy, too. Pick up a variety today and see what uses you can find for these on your project.
