SLIMI Car Body Screws & U-Nuts Kit — 100 PCS Black, Universal Fastener Set, Corrosion-Resistant

SLIMI 100 PCS Car Body Screws and U-nuts kit is a universal fastener set designed to securely replace and repair bumpers, fenders, splash shields and other body panels on most cars, SUVs and trucks.

Keep a reliable stock of body fasteners in your toolbox: this SLIMI set includes 100 black screws, bolts and U-shaped retained nuts engineered to deliver strong clamping, corrosion resistance and long-term durability. Built for common automotive mounting points—under the hood, bumpers, fenders, grilles, side skirts and splash shields—these parts are intended as direct replacements for worn or missing plastic and metal retainers. They’re supplied in a single kit so you can complete multiple small repairs or restorations without hunting for matching pieces.

How do these retainers improve a loose bumper or splash shield?

The SLIMI U-nuts and screws create a stable, vibration-resistant connection between panels and the chassis. The U-shaped clip grips thin sheet metal while the screw compresses the assembly, reducing rattle and maintaining alignment over time.

• U-shaped bracket locks onto panel edges for secure fitment.
• Screw head provides positive torque and prevents backs-out.
• Black finish minimizes visibility and resists weathering.
• Works on both plastic guards and metal mounting flanges.

Will these fit my vehicle’s mounting points?

This kit is intended as a universal solution for many makes and models, covering typical hole sizes and panel thicknesses found on cars, SUVs and trucks. While it fits most standard applications, always compare one of your original clips to the kit before committing to a large repair.

• Designed for common automotive panel hole diameters and sheet thicknesses.
• Suitable for bumpers, fenders, dash mounts, grille and underbody shields.
• Use as direct replacements or temporary repairs while sourcing OEM parts.
• Includes multiple identical pieces to replace groups of fasteners at once.

How easy is installation for a DIYer?

Installation is straightforward and requires only basic tools—no special drills or rivet guns. The U-nut slides over the panel edge or into a slot, then the screw is driven through the mating part to clamp both pieces together.

• No pre-drilling in many cases; fits existing factory holes and slots.
• Install or remove with a standard screwdriver or socket driver.
• Quick replacements let you finish multiple points in one session.
• Sturdy design reduces need for repeated re-tightening.

What are the material and durability features?

The kit parts are manufactured from wear-resistant materials chosen for hardness and longevity. They resist deformation, bending or breaking under normal service conditions and perform well across varied weather exposure.

• High-hardness components resist stripping and bending.
• Durable finish helps curb corrosion in wet or salty climates.
• Engineered for repeated removal and reinstallation during maintenance.
• 100-piece supply reduces the chance of running out mid-repair.

Who this kit is for: If you maintain or restore vehicles—professional technicians, weekend DIYers, detail shops or fleet managers—this SLIMI 100 PCS screws and U-nuts set is a practical, cost-effective way to replace worn fasteners and secure body panels quickly. It’s especially useful when matching OEM clips is time-consuming or when you need a bulk supply for multiple repairs. If you require exact OEM fitment for a specific rare model, use one piece from your vehicle to confirm compatibility before replacing the full set.

Package note: the box contains 100 fasteners. Inspect contents on arrival and contact SLIMI support if quantities or condition differ from expectations.
