Built to classic imperial dimensions for high-load structural mounting points. Our 3/4" OD x 1/2" Height Top Hat Bungs feature a stepped shoulder flange that sits nicely into 3/4" drilled mounting holes, keeping the bung square and flat against your tab or fram tube while tacking and welding.
Machined with a 3/4" (19.05mm) outer diameter and a 1/2" (12.70mm) overall height, these bungs are fully tapped through with 5/16"-18 UNC threads for maximum bolt engagement from either side.
