Premium TC Bros Coped Steel Bungs for Round Tubing

TC Bros coped steel bungs are precision-engineered fabrication components designed specifically for welding to round tubing. These bungs feature a curved notch (cope) that fits flush against round frame tubes, creating a professional, finished appearance with maximum weld surface area. Perfect for custom motorcycle builds where you're mounting components to round tubing.

Available Options:

Thread Sizes: 5/16-18 or 3/8-16
Lengths: 1/2", 1", or 1.5"

5/16-18 Thread / 1/2" Long - Compact size for tight spaces on round tubing
5/16-18 Thread / 1" Long - Standard length for most round tube applications
5/16-18 Thread / 1.5" Long - Extended length for thicker materials or additional thread engagement
3/8-16 Thread / 1/2" Long - Larger thread for heavier components on round tubing
3/8-16 Thread / 1" Long - Most popular size for general round tube fabrication
3/8-16 Thread / 1.5" Long - Maximum strength for heavy-duty round tube applications

Key Features:

Coped Design - Curved notch fits flush on round tubing for professional appearance
Maximum Weld Surface - Curved base provides more contact area for stronger welds
Precision Threading - Clean, accurate threads for reliable fastener engagement
Multiple Sizes - Six configurations to match your specific needs
Quality Steel Construction - Durable materials for long-lasting performance
Professional Quality - Manufactured to TC Bros' exacting standards

Why Choose Coped Bungs:

Coped bungs are the preferred choice when welding to round tubing (frame tubes, handlebars, sissy bars, etc.). The curved notch matches the radius of the tubing, allowing the bung to sit flush against the surface. This creates a cleaner appearance than standard flat-base bungs and provides more weld surface area for a stronger, more reliable connection.

Common Applications:

Mounting to round frame tubes
Sissy bar mounting on round tubing
Handlebar mounting points
Fender strut mounting to round bars
Luggage rack mounting to round tubing
Any application where you're welding to round tubing

Other Fabrication Hardware Options:

Depending on your specific application, you might need a different style of bung or mounting solution:

Alternative Bung Styles:

Standard Threaded Steel Bungs - Traditional flat-base bungs for welding to flat surfaces or when coping isn't required. Best for gas tanks, seat pans, and flat mounting surfaces.
Counterbore Steel Bungs - Designed specifically for socket head bolts with a recessed counterbore for flush, low-profile installations. Ideal for visible mounting points where clean appearance matters.
Radius Style Steel Bungs - Feature a radiused base for improved weld penetration and strength. Best choice for high-stress applications on flat or slightly curved surfaces.

Non-Threaded Mounting Solutions:

Weld-On Steel Mounting Tabs - When you need to mount brackets, fenders, or accessories without threaded fasteners, our mounting tabs provide secure weld-on mounting points in 7 different styles.

Specifications:

Material: Steel
Thread Sizes: 5/16-18 or 3/8-16
Lengths: 1/2", 1", or 1.5"
Style: Coped (curved notch for round tubing)
Finish: Raw steel (ready for welding and finishing)

Perfect For:

Custom motorcycle frame building with round tubing
Chopper and bobber builds
Cafe racer and tracker conversions
Hardtail frame fabrication
Sissy bar installations
Professional fabrication shops
DIY custom builders

Installation Notes:

These coped bungs are designed to be welded onto round tubing at the desired mounting location. The curved notch should fit flush against the tubing for maximum weld surface area. We recommend:

Verify the cope matches your tubing diameter for proper fitment
Test-fit components before welding bungs in place
Ensure proper clearance for fasteners and moving parts
Use appropriate welding techniques for your material
Clean and prep mounting area before welding
Paint or powder coat after installation to prevent rust
Use correct thread size for your application (5/16-18 for lighter components, 3/8-16 for heavier)

Professional installation is recommended if you're not experienced with welding and frame fabrication. Each TC Bros coped steel bung is precision-manufactured to exacting standards for reliable performance and professional appearance on your custom motorcycle build.
