Car Engine Under Cover Splash Shield Bumper Body Bolts Guard Fastener U-nut Clip

AUXITO 40-Piece Kit Metal Construction Universal Fitment Direct Replacement

Product Overview

Your vehicle’s underbody panels, splash shields, fender liners, and bumper covers rely on a network of fasteners to stay securely in place. When those original clips break, rust, or simply give out after years of road exposure, you risk panels sagging, flapping at highway speeds, or even detaching entirely. This AUXITO 40-piece fastener kit delivers a complete set of hex bolts and U-nut speed clips engineered to restore that factory-tight fitment across your car’s most critical body panels.

Each bolt and clip is crafted from high-grade metal that resists corrosion, oxidation, and vibration far better than typical plastic push-type retainers. Unlike disposable trim clips that snap on first removal, these metal fasteners provide reusable, reliable clamping force that holds engine under covers, splash shields, bumpers, side skirts, and fender liners firmly in place. The U-nut design captures the bolt thread securely and distributes clamping pressure evenly to prevent panel distortion or stress cracking.

Whether you’re restoring a classic BMW project, replacing lost hardware after a repair, or upgrading from worn-out fasteners, this kit offers a universal solution that fits a wide range of vehicles including BMW, Toyota, Lexus, Ford, Honda, Acura, Chevrolet, and more. The installation is straightforward with no special tools or modifications required — simply position the U-nut, align your panel, and thread in the hex bolt for a secure, rattle-free hold. At just $9.49 for 80 pieces, it’s an affordable preventative maintenance investment that saves you from costly panel replacements down the road.

Key Features & Benefits

✔ All-Metal Construction for Lasting Durability
Unlike plastic clips that become brittle and crack under UV exposure or cold weather, these metal hex bolts and U-nuts resist rust, corrosion, and fatigue — keeping your panels attached through years of daily driving, rain, snow, and road salt.
✔ 40-Piece Complete Kit for Full Coverage
With 40 hex bolts and 40 matching U-nut clips, you have enough hardware to secure an entire underbody shield, both fender liners, or a bumper cover in a single purchase — no need to hunt for missing pieces mid-installation.
✔ Universal Fitment Across Multiple Makes and Models
Engineered to work with a broad range of vehicles including BMW, Toyota, Lexus, Ford, Honda, Acura, Chevrolet, Buick, Cadillac, and more — whether you’re working on a sedan, SUV, or sports car, these fasteners have you covered.
✔ Tool-Free U-Nut Design for Easy Positioning
The speed clip style U-nut slides onto sheet metal edges and stays put while you align your panel, then the hex bolt threads in smoothly — no awkward holding, no dropped nuts, no frustration.
✔ Vibration-Resistant Hold Stops Panel Rattle
The threaded engagement between bolt and U-nut creates a positive mechanical lock that resists loosening from road vibration, keeping your splash shields and under covers quiet and secure at any speed.
✔ Simple Direct Replacement — No Modifications Needed
Designed as a drop-in replacement for factory hardware, these fasteners match the dimensions and thread pattern of original equipment clips — just remove the old, install the new, and go.

Installation Guide

Difficulty Level: Easy  |  Estimated Time: 15–30 minutes  |  Tools Needed: Ratchet or socket wrench (or standard hex key), optional: trim removal tool for old fasteners. No drilling, cutting, or modifications required.

1
Remove old or damaged fasteners. Use a trim removal tool or flathead screwdriver to carefully pry out any remaining plastic clips or unscrew existing bolts. Discard any corroded or broken hardware.
2
Clean the mounting holes and surface. Wipe away dirt, mud, or debris from the panel holes and the sheet metal underneath. A clean surface ensures the U-nut sits flat and the bolt threads freely.
3
Position the U-nut clip onto the sheet metal edge. Slide the U-nut over the edge of the body panel mounting flange until it clicks or sits snugly. The threaded hole should align with the opening in your splash shield or bumper cover.
4
Align the panel and insert the hex bolt. Hold your under cover, fender liner, or bumper trim in position over the U-nut. Insert the hex bolt through the panel hole and into the U-nut’s threaded receiver.
5
Tighten the bolt firmly but don’t overtighten. Turn the hex bolt clockwise until the panel is drawn snug against the body. Stop when you feel firm resistance — metal U-nuts provide excellent grip without needing excessive torque.
6
Repeat for all fasteners and test security. Install the remaining 39 bolts and clips at each mounting point. Give the panel a gentle tug to confirm it’s secure — a properly installed set will hold firmly with no movement or rattle.

Package Includes

40 × Hex Bolts — Metal, corrosion-resistant, for secure panel attachment
40 × U-Nut Speed Fastener Clips — Threaded metal clips with quick-slide installation
* As shown in product images. Total 80 pieces per kit.
