Description
Stepped Blind Tank Bungs – 1018 Mild Steel
These stepped blind threaded bungs—also known as top hat bungs—are ideal for welding into gas tanks, oil tanks, or any steel fluid container. Precision-machined from 1018 cold rolled mild steel, these bungs feature a flanged design to ensure consistent standoff height and ease of alignment during fabrication.
The larger 7/8" diameter flange provides increased weld surface and load distribution, while the stepped 5/8" body allows you to use a smaller 5/8" hole for installation. Perfect for custom tank fabrication where clean looks and secure fittings are essential.
