How many screws go into a 4×8 sheet of drywall?
Use about 32 drywall screws per sheet of 4-foot by 8-foot drywall installed horizontally on a wall. This total is comprised of four screws on the five middle studs and six screws on each of the two sides.
How far apart should my screws be?

How far apart should drywall screws be on the ceiling?
Space screws a maximum of 12″ apart on ceilings, 16″ on walls and at least 3/8″ from ends and edges of panels. Sink screws to just below the panel surface, leaving the paper intact.
How long should drywall screws be for 1/2-inch drywall?
When working with 1/2-inch drywall panels, use 1-1/4 or 1-3/8-inch nails or screws. When working with 5/8-inch drywall panels, use 1-3/8-inch or 1-5/8-inch screws.
Is it better to screw or nail drywall?
While nails tend to be more flexible and hold up better against shear pressure—or lateral force—screws have much better grip and tensile strength, which ultimately keeps drywall from pulling away from the studs. When it comes to holding power, screws simply can’t be beaten.
What is the screw pattern for drywall?
Drywall screws pattern Drywall screws should be installed every 12 inches. This means that when using 48 inch wide sheets, you will have 5 screws in each stud when the sheets are hung perpendicular to the framing; two on the edges and 3 in the field.
Can you put too many screws in drywall?
First, do not use too many screws. When fastening drywall to walls I attach the drywall with two fasteners every 16 inches in the field, and one every 16 inches on the edges. Ceilings are fastened 12 inches on center.

How far should a screw penetrate wood?
This pilot hole should be deep enough so that it penetrates the wood a distance of about one-half to two-thirds of the screw’s threaded length. If you are planning to countersink the screw head, a third hole, equal to the diameter of the head, will be needed at the surface.
What is the maximum spacing for screw fixing plasterboard to a ceiling?
Table 6: Acceptable fixing centres and fixings Fixing Location and spacing Nail Walls and ceilings: approximately 150mm centres (eight per linear metre) Screw Ceilings: approximately 230mm centres (eight per two linear metres) Walls: approximately 300mm centres (five per linear metre).
Should drywall joints be tight?
Drywall Joints Are Too Tight Close drywall joints are desirable, but not too close as to cause problems. If you have two adjoining sheets of drywall that fit snugly side-by-side, you risk breaking off the drywall in ways that you didn’t imagine.
Is it better to hang drywall vertical or horizontal?
On commercial jobs, fire codes often require seams to fall on the entire length of the framing, so the drywall must be hung vertically. For walls 9 feet high or shorter, hanging the drywall horizontally has a number of benefits. Fewer seams. Horizontal hanging reduces the lineal footage of seams by about 25%.

How far apart should plasterboard screws be?
Since drywall screws attach more securely, you can use fewer screws and space them farther apart — 12 to 16 inches (30.5 to 40.6 centimeters) is sufficient.
