Bemaka automotive fastener kit 260-piece U-nuts, fender bolts & rivets — M4.2 M6 M8 1/4", corrosion-resistant case

Bemaka 260-piece automotive fastener kit is a complete set of metal U-nuts, self-tapping washer-head bolts and plastic push rivets to replace lost or worn bumper, fender liner and trim panel hardware.

If you work on vehicles—professionally or as a DIYer—missing body panel fasteners are a constant nuisance. This Bemaka assortment gathers commonly used sizes and types into a single, compartmented case so you can repair bumpers, splash shields, wheel wells and interior trim without hunting for individual parts. The set combines rust-resistant carbon steel bolts and U-nuts with durable plastic retainers to cover most common mounting points on cars, trucks, SUVs and vans.

What parts are included and which threads fit my car?

The kit contains 260 pieces across multiple fastener styles and sizes designed for common automotive body applications. It includes washer-head self-tapping bolts, metal U spring nut clips in different profiles, and plastic push rivets for panels and liners.

• M4.2 (1.41) bolts — smaller trim and splash shield uses
• M6 (1.1) bolts — medium mounting points and brackets
• M8 (1.25) bolts — larger body attachments
• 1/4" bolts — imperial option for some vehicles and accessories
• Various metal U-nuts and plastic retainers to match panel holes

How durable are these fasteners for undercarriage and engine bay use?

All metal bolts and U-nut clips are carbon steel with an anti-rust surface finish to resist corrosion from road salt and moisture. The hardware is built to endure vibration and road impacts commonly found in wheel wells and under-hood areas, while the plastic rivets are formulated to be flexible and resist cracking during installation.

• Carbon steel construction for strength and longevity
• Corrosion-resistant surface coating for outdoor exposure
• Plastic push rivets with good toughness to prevent breakage
• Suitable for repeated removal and reinstallation in many scenarios

How does the storage case help with repairs and organization?

The kit ships in a compact handheld plastic case with divided compartments so you can quickly locate the exact fastener you need. Clear separation prevents mixing different sizes and types, saving time during roadside or garage repairs and reducing the chance of using the wrong clip or bolt.

• Divided compartments for fastener sorting
• Portable design fits in a toolbox or car trunk
• Sufficient quantities for multiple repairs without immediate replenishment
• Helps avoid last-minute trips to auto parts stores

Which vehicle jobs is this assortment best for?

This assortment is intended as a general replacement set for exterior and some interior body fasteners. It’s ideal for fender liners, bumpers, engine splash shields, wheel well covers, interior trim panels and small body brackets, but you should always verify thread size and clip profile before installation.

• Repairing or replacing bumper and fender liner hardware
• Securing splash shields and undercarriage panels
• Refastening interior and exterior trim pieces
• Keeping emergency spares for roadside quick fixes

If you perform routine maintenance, restore damaged panels, or maintain a fleet, this set helps you fix common mounting problems quickly—just confirm the thread and clip type match your vehicle before fitting.
