Use the screws, they make a better and tighter connection to the wire. The holes just use a spring to hold the wire against a flat surface inside the receptacle.
To fix a loose door hinge, you can tighten the screws on the hinge with a screwdriver. If the screws are stripped or the holes are worn, you may need to replace the screws or use longer screws to secure the hinge better.
Inside the "holes" are springy brass fingers that grip the plug prongs when you insert the wall plug, making connection with your home's electrical system.
Yes, the screw holes are too big for the screws to fit properly.
You can find screws with holes in them at hardware stores or online retailers that specialize in fasteners and hardware supplies.
Pocket holes typically require 1 1/4-inch coarse-thread screws for softwoods and 2 1/2-inch coarse-thread screws for hardwoods.
You need to re-bore the existing holes or drill new holes. :) Simplest solution: Use self-threading screws slightly larger than the original screws.
The ones that go into the holes.
Long skinny drill bits are commonly used in woodworking projects for tasks such as creating pilot holes for screws, drilling holes for dowels, and making intricate designs or patterns. They are also useful for drilling holes in tight or hard-to-reach spaces and for creating precise holes for wiring or cables in furniture pieces.
Pilot holes are small holes drilled into wood before inserting screws. They are important in woodworking projects because they help prevent the wood from splitting and make it easier to drive the screws in straight.
To fix loose door hinges, you can tighten the screws on the hinges using a screwdriver. If the screws are stripped or the holes are worn out, you can use longer screws or fill the holes with wooden toothpicks or dowels before reattaching the hinges.
To install an electrical box for brick, you will need to first mark the location on the brick where you want to place the box. Then, use a masonry drill bit to create holes for the screws that will secure the box to the brick. Next, insert plastic anchors into the holes and attach the electrical box using screws. Finally, connect the electrical wiring to the box following proper safety procedures.
The holes on the back are there for quick wiring. You strip the wire and then insert it into the holes. It is held in place by spring tension. I do not recommend you wire the outlet by using these holes. From my experience the wires are not secure enough. Strip the wire and wrap it around the screws and tighten it securely which is what all the good electricians I know do. Takes a little longer but IMO it is more secure.
