01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision Fastening for GM Bumpers
The outer bumper cover is a vehicle’s most visible boundary, yet its security relies on small, often overlooked components. When these fasteners wear or break, the panel can shift, rattling against the chassis during daily drives.
This kit provides twenty dedicated U-nut fasteners, machined to match specific GM models. It suits both professional technicians and DIY enthusiasts performing bumper disassembly, maintenance or component replacement work.

The U-shaped structural design creates a secure anchor point within the bumper assembly, holding the plastic cover firmly in place against vibration and road debris.

04PRACTICALITY
Twenty Pieces for Routine Maintenance
A single pack contains twenty fasteners, a quantity sufficient to cover most common repair tasks or a full set of replacements for one side of the vehicle. This volume makes it an ideal stock item for independent repair garages or dealer service departments handling high volumes of bumper work.
05PROCESS
Simple Fitting for Stable Connection
The fitting process is straightforward, requiring no complex tools beyond standard automotive hardware. Once installed, the U-nuts provide a stable connection effect, preventing the bumper from loosening over time. This reliability supports both quick fixes and detailed restoration projects.
