GM License Plate Screws: Duo-Drive Truss Head, #14 x 16mm, Box of 100
These GM license plate screws are the Duo-Drive truss head screw that GM uses on the front and rear plates of many Chevrolet, GMC, and Buick cars and trucks, GM part number 9423101. Each screw has a #14 (1/4″) thread, a 16mm length, and a Dacromet finish, and they come 100 to a box. If you need an OE look on a GM vehicle, these GM license plate screws are the right choice.
Dealerships, used car lots, and body shops go through license plate screws every day. Plates come off for transport tags, dealer plates, bumper repair, and new plate frames, and the old screws are often rusted, stripped, or missing. A box of 100 GM license plate screws keeps the right screw in the drawer, so nobody has to dig through a coffee can of mixed hardware.
How These GM License Plate Screws Are Made
The truss head is wide and low. It covers more of the plate’s mounting slot than a pan head, sits close to the plate, and gives a clean finished look. The Duo-Drive recess takes either a Phillips head or a flathead screwdriver, so whoever is putting the plate on can use whatever tool is in reach.
The Dacromet finish is a corrosion-resistant coating made for parts that live outside the car. License plate screws sit right in the spray of rain, road salt, and car wash chemicals, and a coated screw holds up to that far better than a bare one.
What makes this one worth keeping in the garage:

- #14 (1/4″) thread, 16mm length
- Dacromet corrosion-resistant finish
- GM part number 9423101, OE look
- Used on many Chevrolet, GMC, and Buick cars and trucks
- Box of 100 for dealer and shop use
Will These GM License Plate Screws Fit My Car?
Most Chevrolet, GMC, and Buick vehicles take a #14 (1/4″) license plate screw. Our License Plate Screw Sizes guide shows the screw size for each car make and which of our screws fits it. The factory length is made to hold the license plate by itself. If you add a license plate frame or cover, you may need a longer screw, such as our License Plate Screws #14 x 3/4.
Installing GM License Plate Screws
- Remove the old screws and check the push-in nuts behind the plate. Heat and cold make the original nuts brittle over time, so replace any that are cracked or spin in place with our License Plate Nylon Inserts.
- Line the plate (and frame, if you use one) up with the mounting holes.
- Start each GM license plate screw by hand, then snug it down with a Phillips head or flathead screwdriver. Don’t overtighten; the plate only needs to be held firmly.
Tip: Dealers who move one plate from car to car for test drives can skip the screws altogether with our Magnetic License Plate Holder.
