148 tubular flat U-nuts and J-nuts in a pre-packaged assortment covering the most common clip sizes used in domestic vehicle body and trim assembly. U-nuts and J-nuts snap onto panel flanges without a back nut or access to the reverse side, making them the standard solution for attaching interior trim panels, underhood covers, and body molding where a conventional nut would be impossible to reach.
What's Included
- Tubular flat U-nuts — spring steel clips that snap onto panel flanges and accept a threaded screw
- J-nuts — for thicker flanges and panel edges where U-nut geometry applies
- Multiple clip sizes covering the most common domestic vehicle applications
- 148 pieces total
Specifications
| Fastener types | Tubular flat U-nuts, J-nuts |
| Material | Spring steel |
| Finish | Phosphate |
| Application | Domestic vehicle body panels, trim, and underhood covers |
| Total pieces | 148 |
| Supplier | Auveco |
Best For
- Auto body and collision shops — U-nuts and J-nuts are consumed during panel removal and teardown; having a mixed assortment on hand avoids delays when reinstalling trim
- Fleet maintenance operations — domestic fleet vehicles use U-nuts extensively in door panels, headliners, and underhood covers; replacing broken clips is a routine maintenance task
- Dealership service departments — technicians pulling panels for audio, upholstery, or electrical repairs frequently break clip fasteners and need replacements on the spot
- Restoration shops — original U-nuts and J-nuts deteriorate or break during teardown; a mixed assortment covers the range of sizes used across domestic models
Understanding U-Nuts and J-Nuts
U-nuts (also called speed nuts, clip nuts, or spring nuts) are one-piece spring steel fasteners that snap onto the edge of a panel flange and provide a threaded engagement point for a screw — without requiring access to the backside of the panel. They're used wherever a conventional nut can't be placed because the panel cavity is enclosed.
Tubular flat U-nuts have a flattened tube body that engages a specific flange thickness range. The screw is driven into the center channel, which expands the clip and locks it to the panel.
J-nuts use a J-shaped clip profile to engage the edge of a flange. They're commonly used in areas where the flange is thicker or the access angle makes a standard U-nut difficult to install.
When replacing U-nuts or J-nuts, the critical dimensions are thread size (to match the screw) and panel thickness range (to ensure the clip snaps onto the flange securely). Need help identifying the right size for your application? Contact us.
