ecocstm 160-piece metal screw and retainer clip kit supplies 14 popular sizes of galvanized, carbon-steel fasteners for bumpers, fender liners, hood trims and other automotive plastic panels.

Keep repair and trim work simple with a mixed kit built to fit many European models. These self-tapping screws and retaining clips are made from galvanized carbon steel for improved corrosion and temperature resistance, and the assortment covers common fastening needs when replacing splash guards, bumper covers, air ducts and interior plastic trims. The set is sized to reduce trips to the hardware store and give you durable replacements that resist loosening from vibration.

Which vehicle parts can I use these screws and clips on?

These fasteners are intended for non-structural exterior and interior trim where self-tapping metal screws or retainers are required. They commonly secure splash shields, fender liners, bumper covers, air ducts, wheel well trims and dash or door plastic panels.

• Splash guards and skid plates: quick replacements after damage.
• Fender liners and wheel wells: resist road debris and moisture.
• Bumper covers and air ducts: reattach panels after removal.
• Interior trims and plastic clips: restore loose panels and finishes.

How durable are the metal fasteners in this kit?

Each piece is manufactured from carbon steel with a galvanized finish to slow corrosion and withstand heat from engine bays and road exposure. The threads and heads are engineered for deep engagement so fasteners stay tight under vibration and repeated use.

• Galvanized carbon steel resists rust and road salts.
• Deep, even torque threading minimizes loosening.
• Designed for sustained use in under-hood and wheel-well areas.

What sizes and quantities are included, and why does that matter?

The kit contains 160 metal screws and retainer clips across 14 different sizes to match a wide range of panel hole diameters and material thicknesses. Having multiple sizes reduces the risk of using the wrong fastener that can strip plastic or fail prematurely.

• 160 pieces total — enough for several repair jobs.
• 14 popular specifications to fit common OEM hole sizes.
• Assortment approach saves time vs. buying single sizes.

Is this kit compatible with my Audi or other European car?

The assortment is compatible with many Audi models (A3, A4, A5, A6, A7, A8, Q3, Q5, Q7, Q8, R8 and similar), and works for other makes using comparable clip and screw standards. Always check the hole size and material before installation and keep spare pieces for future maintenance.

• Fits a broad list of Audi models and similar European vehicles.
• Useful for both OEM repair and do-it-yourself panel work.
• Recommended to verify dimensions before final assembly.
