Using wood screws on concrete will make up things bad in the long run. Concrete walls don’t hold up well the extremely coarse and sharp threads. Most likely, the wall will get damaged if you push to install wood screws, and the potential of holding weight using wood screws will be less than what the masonry screw can provide.

  • Wood screws have sharp threads supposed to bite into wood grains. Concrete walls can be damaged.
  • Wood screws have sharp tips when inserted into concrete they may fall
  • Wood screws typically come up in long sizes. 
  • Wood screws are tapered, cannot hold on concrete walls.
  • Wood screws have flat heads, inserting them on concrete can damage the surface.

Thus, always be sure to insert the right screws in the right material to get things just perfect. And to save yourself from troubles to come.

How to drill a screw into concrete?

Use masonry screws

For drywall, concrete, the masonry screws work well. Unlike wood screws these are not self-tipping as rather have a flat tip, needing pilot holes to insert them. 

Choosing the right bit

Check the head, hex, philps, or crossed. Not every screwdriver driver satisfies all types of heads up. Choose the drill or manual screwdriver that can fit onto the head. A thing to notice before making a purchase for screws.

Mark Your Surface

Mark the spot on the concrete where the hole will be drilled. Be careful not to puncture or damage anything behind the concrete such as wires, pipes, etc.

Prepare Your Drill

Prepare yourself, wear glasses to protect your eyes from dust coming off from the walls. While making pilot holes, the hole should be wide enough. And It is recommended that the end depth of the hole should be set 1/4 inch further than the screw size.

Use Anchors If Required

A screw anchor may be needed if you aren’t using the right screws or the hole is bigger than you anticipated. Anchors can help make a tight bond as they expand from the inside of the hole. Ensuring maximum strong ability.

Recommended screws to use in concrete or masonry

Some popular types of screws

WOOD SCREWS

Wood screws are known for their coarse threads that grip wood securely until the top of the screw shaft, just under the head, is smooth. A unique design that allows two wooden boards to make a proper joint- the unthreaded part helps joint woods to move while the threaded part bite into the wood. Choose the length that can go deep by 2/3 of a wood board.

One of the identical properties of there is “self-tapping,” no more predrilling holes are needed. The flatheads are equally popular for these screws. The reason being here, to make the heads invisible.

DRYWALL SCREWS

Screws of this type are only designed for installing drywall panels and range from 1 inch to 3 inches in length. Unlike wood screws, heads are not flat just for a reason to avoid damaging the beauty of drywall panels. Inserting them keeps the surface smooth and undamaged. The self-tapping ability makes the job done faster.

MASONRY SCREWS

To insert a masonry screw, you must predrill a hole before inserting it as they cannot bore their own holes since the tip is flat. Speaking of heads, that can vary from hex-head to Philip’s heads, choosing the right head depends on the type of drill you have in your workplace.
