This article provides a simple Number Plate Drilling Guide for car dealerships, number plate suppliers and their customers. Follow this guide and you’ll avoid cracking or delaminating your replacement number plates, when you drill new holes.
Before you can fit a replacement number plate, you will need to remove the existing one. Simply unscrew the holding screws and remove the old plate. As can be seen in the image above, the area under the number plate will be dirty. So now is a perfect time for a real clean.
Note: Keep your old number plate handy, you’ll need it later.
Fitting your number plates using screws is an easy process with a few simple steps. First you’ll need to a template to ensure the holes are in the right place. And you’ll want to avoid damaging your new plates when you drill them. Simply follow the steps below and you’ll soon be screwing the plate to your car.
When drilling you’ll start at the back to avoid damaging the plate. So place your new number plate flat on your worktop, with the rear facing upwards. Now position the old one on top and line them up so that their centres match. Next, using a black marker and using the old screw holes, make a mark or cross on the new plate.
When drilling a hole, you only get one chance to get it right. So we’re going to use a common technique of using masking tape to help stop the drill slipping. Apply a small piece of masking tape on top of your drilling marks. Masking tape is thin enough, so you should still be able to see your mark through it.
Note: If your marks aren’t visible, re-use your old plate and mark the drilling points on top of the masking tape.
Use a 6mm diameter acrylic bit for drilling your holes. Carefully position the drill at one of your drilling points. Start the drill and gently begin to make a hole. Allow the bit to do the work, avoid applying to much pressure.
Remember: Drill from the rear of number plate to the front. Placing wood underneath the number plate might help avoid damage.
Once you have drilled your holes remove the masking tape from the plate. If there’s any burrs or lumps, take them off. This will help your screws fit flush with the plates surface. Now you’re ready to fit the plate to your vehicle.
Position the plate in the correct location on the vehicle by partially attaching screws to both holes. Now carefully tighten up your fixings, ensure you don’t over tighten them. Finally polish the plate using circular motions with a soft cloth to remove finger prints or dirt.
Remember: Select coloured screw caps that correspond with the holes location on the number plate. Don’t use cap colours which alter the appearance of the registration mark.
