The 411 WORKS 1.5" Flat Weld Bungs are precision-machined fabrication components designed to create strong, clean threaded mounting points on flat surfaces. Manufactured in-house in the USA on HAAS CNC machines, each bung is machined from high-quality North American 1018 steel for custom automotive and motorsport fabrication.

Available with M10 x 1.5 or 3/8-16 threads, these bungs feature a weight-optimized design with material removed from the backside rather than using a completely solid construction. A consistent 1/8-inch sidewall is retained to provide a practical welding surface during fabrication.

1018 Steel Construction: Manufactured from high-quality North American 1018 steel for a durable and weldable fabrication component.

Flat Weld-On Design: Designed for welding to compatible flat surfaces where a threaded mounting point is required.

Two Thread Options: Available with M10 x 1.5 or 3/8-16 threads to accommodate different mounting requirements.

Weight-Optimized Construction: Material is removed from the backside to reduce unnecessary weight rather than using a completely solid design.

1/8-Inch Weldable Sidewall: Features a consistent 1/8-inch sidewall designed to provide a practical surface for welding.

CNC-Machined Construction: Precision machined in-house using HAAS CNC equipment for consistent dimensions and quality.
