Downhill 100-Piece Fender, Bumper & Undertray Fastener Kit — Universal U-Clips, Screws & Bolts (Black/Gold)

Downhill's 100-piece fender, bumper and undertray fastening kit supplies a full set of U-clips, screws and bolts to secure splash guards, under covers and trim on most passenger vehicles.

This kit gathers commonly used plastic and metal fasteners so you can replace lost clips, repair loose splash guards or complete routine trim work without hunting for single parts. The set combines ABS plastic clips with metal screws and bolts in a variety of styles and two-tone U-clips to match different attachment points on fenders, bumpers, engine undertrays and interior trim panels.

Which parts are included and how many of each will I get?

The Downhill kit contains 100 pieces in five categories, sized and finished for general automotive use. Quantities are balanced for small repair jobs and maintenance tasks.

• 20 metal bolts — durable fastening where threaded engagement is needed
• 20 metal screws — conventional panel screws for covered holes
• 20 black U-shaped clips — hold panels from the edge or lip
• 20 gold (brass-colored) U-clips — alternate finish for visible areas or specific fitment
• 20 plastic push clips — lightweight, corrosion-resistant panel retainers

How do these clips and screws perform on different car parts?

The kit is designed to work across exterior trim and underbody panels where clips, screws and U-clips are commonly used. Materials and one-piece molding improve longevity and resist loosening from vibration.

• ABS plastic clips: resist moisture and temperature swings under the vehicle
• Metal screws and bolts: provide stronger clamping force for structural points
• U-shaped clips: clamp panel edges without pre-drilling in many cases
• Different finishes: help match visible areas and avoid galvanic corrosion

How easy is installation and what tools do I need?

Installation is straightforward for anyone with basic automotive tools and a little experience removing trim. Clean the area first, wear gloves to protect hands, and use common hand tools to seat clips and tighten screws.

• Tools: flat or trim pry tool, Phillips or Torx driver, socket set for bolts
• No special drilling usually required—U-clips grip panel lips and slots
• Replace damaged clips one at a time to preserve alignment of adjacent panels
• Hand-tighten screws and bolts to avoid stripping plastic clips

Will these fasteners fit my vehicle model?

The kit is sold as a universal assortment for most cars, trucks and SUVs rather than a model-specific set. While the pieces cover a wide range of common fastener types, verify clip style and diameter against your vehicle’s original parts for critical fitment points.

• Common fit: works for many fenders, bumpers, engine covers and splash shields
• Check: compare head shape, shaft diameter and clip width to originals
• Keep extras: the 100-piece count gives spares for future repairs

Who is this for? DIY enthusiasts, home mechanics and professional shops that perform routine bumper, fender and undertray work will find value in this Downhill assortment. It’s useful for emergency roadside repairs, restoration projects and scheduled maintenance where replacing brittle or missing clips restores panel alignment and reduces rattles. If you need a starter stock of common fasteners to avoid delays during trim and splash-guard work, this kit provides a compact, mixed supply suitable for many passenger vehicles.
