This hex nut fastens the bumper brackets and mounting hardware to the chassis structure. Its precise thread pitch and corrosion-resistant finish ensure consistent torque retention, reliable alignment, and vibration-free bumper support in all driving conditions.
Over time, moisture, vibration, and age can cause original hardware to rust, seize, or lose clamping strength. Aged nuts may compromise bumper alignment or make disassembly difficult during service or repainting.
When to Replace:
• During front or rear bumper removal, alignment, or restoration.
• If existing hardware is rusted, stripped, or corroded.
• As part of preventive maintenance during bodywork or repainting.
