Description
Stepped 1/2"-20 Weld-In Bung for 1" & 1.25" Tubing – Mild Steel
These large weld-in stepped bungs—also known as top hat bungs—are precision-machined for 1/2"-20 fine thread bolts, the same thread size commonly used for handlebar riser mounting. Designed to slide into 1" or 1.25" OD tubing with .120" wall thickness, the stepped design ensures quick and consistent fitment. The oversized flange is 1/4" larger in diameter than the tube OD, providing extra weld surface for strength and durability. Ideal for building custom T-bars, handlebars, or a variety of fabrication and chassis applications.
