ecocstm Metal Car Screw & Retainer Clip Kit 160 PCS, 14 Sizes - Galvanized Carbon Steel Assortment

This kit gathers a broad range of common automotive fasteners so you can replace lost or damaged trim screws quickly without guessing sizes. Made from galvanized carbon steel for improved rust resistance and heat endurance, the set targets Audi models (A3/A4/A5/A6/A7/A8/Q3/Q5/Q7/Q8/R8 and similar) while remaining useful across many makes that use comparable retainer designs. The included pieces cover frequent underbody, bumper and interior trim fastener needs for routine maintenance and small repairs.

Which parts are included and why does the variety matter?

The box contains 160 pieces across 14 distinct sizes to match many factory screw and clip locations. A broad selection reduces the need to buy single-size packs when multiple fastener types are required for one job.

• 14 sizes include short self-tapping screws, longer body screws and assorted retainers for clips and flanges
• 160 total pieces provide spares for repeated repairs or multi-area work
• Organized assortment helps you identify the right size quickly during installation

How durable are these screws and where can I use them?

Manufactured from carbon steel with a galvanized finish, these fasteners resist corrosion and tolerate elevated under-hood and underbody temperatures better than plain steel. They’re intended for non-structural applications that need reliable clamping and vibration resistance.

• Suitable for bumpers, splash guards, fender liners, air ducts and plastic trim
• Galvanized finish improves corrosion resistance in wet or road-salt environments
• Engineered torque profile reduces loosening from vibration

How do I pick the correct screw or clip for my repair?

Match diameter, head style and length to the original fastener whenever possible. If you’re unsure, start with the closest diameter and test fit on an inconspicuous area to confirm proper thread engagement and head clearance.

• Compare head shape (Phillips, hex, pan head) and length to the factory part
• Use the shortest screw that fully engages threads without bottoming out
• Keep spare pieces handy for trial fittings before final installation

Can this kit be used on non-Audi vehicles?

Yes — while the kit lists compatibility with many Audi models, the sizes included are common across numerous makes and years. It’s a practical general-purpose assortment for most cars that use similar clip-and-screw fasteners.

• Works on many European and Asian vehicles sharing common trim fastener styles
• Ideal for DIY mechanics, detail shops and fleet maintenance teams
• Good for emergency roadside fixes and scheduled trim replacements
