OAUTOO 180-piece Automotive Flat U Nut Kit — 18 Sizes (M4.2–M6.3) organized assortment for panels & trims

This kit gathers 180 flat U-style body nuts in commonly used sizes (#8, #10, #12, #14) designed to replace fatigued or missing clips on vehicle panels, trims, bumpers and interior components. Built for broad vehicle compatibility, the set covers multiple center-to-edge hole spacings so you can match the exact fit without searching multiple suppliers. Everything is organized for fast identification and use during road-side repairs or shop work.

Which parts and sizes are included in the kit?

The assortment contains 18 specific flat U nut variants, ten pieces each, totaling 180 clips. Sizes accommodate screw threads M4.2 (#8), M4.8 (#10), M5.5 (#12) and M6.3 (#14), and each variant lists its center-of-hole-to-edge measurement to help you pick the right clip for the panel hole.

• Four screw-size groups: #8, #10, #12, #14 for common automotive fasteners.
• Eighteen unique center-to-edge hole spacings to match vehicle panel geometry.
• Ten pieces per variant for on-hand spares and repeated repairs.

How durable and reliable are these flat U nuts?

OAUTOO designed these clips with long service in mind, using materials selected for repeated installation and resistance to typical automotive stresses. They’re intended as direct replacements for OEM-style flat U nuts, restoring secure connections where clips have corroded or broken.

• Manufactured for consistent fit and mechanical retention on sheet metal and plastic edges.
• Suitable for interior and exterior body panels where standard U nuts are used.
• Packaged to prevent mixing so you can pick the correct size quickly.

Which vehicles will these clips fit?

The kit targets broad compatibility: it fits many domestic and import makes using these common screw sizes. While not vehicle-specific, the range of spacings and sizes covers the majority of fastener locations on passenger cars and light trucks made by mainstream manufacturers.

• Compatible with many Ford, GM, Honda, Toyota, Nissan, Mazda, Subaru, Hyundai, BMW and VW models.
• Ideal for door panels, bumper covers, splash shields, trim and interior components.
• Use center-to-edge measurements to confirm match for unique panel hole layouts.

How do I choose the right clip from this assortment for a repair?

First measure the screw size and the distance from the hole center to the panel edge on the vehicle. Then locate the variant in the kit that lists the matching center-to-edge dimension and screw size. If uncertain, start with a single test clip from the same screw-size group to confirm fit before replacing multiple fasteners.

• Measure screw thread or match with existing screw to identify #8/#10/#12/#14 grouping.
• Measure center-of-hole to panel edge and compare to the kit’s spacing options.
• Test-fit one clip before completing the repair to ensure secure engagement.

Who is this for: This OAUTOO kit is designed for DIY car owners, mechanics, and restoration shops that need a versatile, organized supply of flat U nuts for fast panel and trim repairs. If you service multiple vehicle makes or want an all-in-one replacement set for emergency fixes, this assortment reduces downtime and avoids multiple small orders for single sizes.
