Downhill 100‑Piece Car Body Fastener Kit — Fender, Bumper & Undertray Clips and Bolts (Black/Gold)

Downhill 100 PCS car body fastener kit supplies the screws, U-clips and bolts needed to secure fenders, bumpers, undertrays and engine covers for most vehicles.

This comprehensive kit bundles 100 durable pieces — metal bolts, metal screws, black and gold U-shaped clips and plastic retainers — designed to replace lost or worn body fasteners during routine maintenance or repairs. The components pair ABS plastic clips with steel hardware for corrosion resistance and mechanical strength, making them suitable for splash shields, inner fender liners, engine undercovers and bumper attachments. Below you’ll find clear answers to common buyer questions so you can decide whether this kit fits your project.

What exactly comes in the Downhill fastener kit?

The kit contains a balanced mix of clips and fasteners chosen to cover multiple common mounting points on a vehicle’s body. It’s meant to be a ready supply for replacing the most frequently failing pieces.

• 20 metal bolts — zinc-plated for rust resistance and firm threading.
• 20 metal screws — for secure anchoring where threaded holes are available.
• 20 black plastic clips — ABS construction for flexibility and weather resistance.
• 20 gold-colored U-clips — plated metal for tight panel engagement.
• 20 U-shaped plastic/ABS clips — fit edges and flange mounting points.

How do these clips and screws perform in everyday conditions?

Materials and design focus on durability under road conditions, with resistance to moisture, temperature swings and vibration. The ABS clips resist cracking and the metal fasteners resist corrosion to maintain hold over time.

• ABS clips provide impact and environment resistance without brittle failure.
• Plated metal bolts and screws reduce corrosion on exposed mounting points.
• One-piece clip designs minimize sliding and loosening from vibration.
• Mix of metal and plastic types covers both threaded and push-fit applications.

Which vehicle parts can I use these fasteners on?

The kit is intended as a universal selection for body panels and undercarriage trim across many makes and models. It’s ideal for areas that commonly lose clips or need replacement after repairs.

• Fender liners and inner wheel arch trims.
• Bumpers, fascia and lower splash guards.
• Engine undertrays, belly pans and chassis covers.
• Hood insulation pads and light mounting trims where compatible.

How should I install these fasteners safely and correctly?

Installation is straightforward but benefits from basic prep and the right tools. Clean the mounting surfaces, wear gloves, and use screwdrivers, a trim removal tool or small socket as needed to seat clips and tighten bolts without over-torquing.

• Remove old fasteners and clean dirt and grime before fitting replacements.
• Use a trim tool to pry panels gently and avoid damaging surrounding clips.
• Hand-start screws and bolts, then tighten until snug — don’t overtighten plastic clips.
• Match clip type to panel thickness or flange style for best retention.

Who is this for: The Downhill 100 PCS kit is for DIY mechanics, mobile detailers and body shops who need a versatile stock of replacement fasteners for routine maintenance, collision repair touch-ups or to restore loose splash guards and liners. It’s also convenient for vehicle owners who prefer to do small repairs themselves and want a variety pack that covers most mounting scenarios without multiple trips to the parts store.
