50 Pcs Fender Liner Screws Compatible with Gm 11548270

These 50 Otoolling fender liner screws are a ready-to-use replacement kit (fits GM 11548270) for securing splash shields, bumper covers, grille panels and inner fender components.

If you need a bulk supply of matching fasteners to restore or maintain exterior automotive panels, this set delivers consistent, corrosion-resistant screws sized to match original mounting points. Each screw is made from manganese steel with a protective zinc finish, sized 4 x 19 mm with 20 mm washers, and accepts a T15 bit—designed to thread into plastic and thin metal for reliable fastening after repairs or panel replacement.

How do these screws make replacing a fender liner or splash shield easier?

They combine drilling, tapping and locking in one part so you can secure liners without hunting for multiple fastener types. The star-shaped drive head improves torque transfer and reduces cam-out, helping you install quickly and cleanly.

• Includes 50 identical 4 x 19 mm screws and 20 mm washers for consistent repairs
• Star (Torx-style) head reduces stripping and works with T15 bits
• Threads into plastic or thin sheet metal for a tight hold
• Black zinc finish gives a tidy, uniform appearance after installation

Will these fasteners withstand road conditions and corrosion?

The screws use manganese steel and a galvanized/zinc surface treatment to resist rust and tolerate temperature swings common to road use. While not stainless steel, the coating improves longevity against salt, moisture and grime compared with untreated fasteners.

• Manganese steel body for strength under vibration and impact
• Zinc/galvanized coating to slow corrosion from water and deicers
• Suitable for exterior panels exposed to road spray and weather
• Black finish hides wear and blends with typical under-hood or bumper colors

Are these screws compatible with my vehicle and installation tools?

They are manufactured to match common OEM 11548270-style fasteners and fit many GM and other models that use similar liner clips and splash shield bolts. Installation requires a standard T15 driver bit or compatible Torx tool and is appropriate for DIY or shop use.

• Dimensions: screw 4 x 19 mm (0.16 x 0.75 in); washer OD 20 mm (0.8 in)
• Compatible with T15 screwdriver bits and Torx drivers
• Intended for fender liners, splash shields, bumper covers and grille panels
• Pack of 50 covers multiple repairs or provides spares for future maintenance

What should I know before buying and installing these fasteners?

Confirm the OEM fastener size used on your vehicle before replacing parts—this kit is sized to fit common 11548270-style mounting holes but may not match every model. Keep small parts away from children and pets; follow vehicle manufacturer guidance when fastening safety-related panels.

• Check original fastener dimensions against 4 x 19 mm and 20 mm washer size
• Allow for slight measurement variance due to manual sizing
• Color may vary slightly from on-screen images
• Contains small pieces—store securely to prevent choking hazards

Who is this for: Professional mechanics and home DIYers who service exterior body panels and need a reliable bulk supply of matching fasteners will find this Otoolling kit useful. It suits collision repair shops, fleet maintenance, and vehicle owners performing routine panel work who want uniform, corrosion-resistant screws that simplify installation and reduce the need to mix different clip types.
