The most secure way to hang objects from drywall is to screw a hanger into the wall or ceiling framing; a variety of wall anchors are available for hanging moderately heavy objects between studs or ceiling joists.
Does screwing into a joist weaken it?
When weight is applied to a joist, the top edge goes into compression while the bottom edge goes into tension. Improperly sized or placed holes and notches weaken the joist, make it bouncy and saggy, and provide an easy place for it to crack and fail.
How much weight can I hang from a ceiling joist?
If you have another floor above your garage, the ceilingfloor structure can usually support up to 40 lbs/SqFt (including the weight of the floor above it). If you do not have another floor above, the ceiling trusses may only be able to hang a maximum of 10 lbs/SqFt.
Is it safe to drill into ceiling?
Probably not the best thing to do. Not only do you have electrical wires, perhaps water lines, but also they are not necessary solid. Remember that ceilings are drywall nailed to supporting beams (Joists). … If you are hanging something heavy on the ceiling, find the joists so that you have something solid to screw into.
How much of a joist can be notched?
Should be no deeper than 0.125 times the depth of the joists. Should be no closer to the support than 0.07 times the span and no further away than 0.25 times the span.
Are ceiling joists load bearing?
Walls that run perpendicular (at a 90 degree angle) to the ceiling joists are load-bearing. Walls that run parallel (in the same direction) as the ceiling joints are non load-bearing. Ceiling joists are spliced over the wall.
How much weight can your ceiling hold?
A standard drywall ceiling can hold up to 20 pounds of direct weight. A good example is a small hanging plant or ceiling fan. But you will still need to use some reinforcement before hanging such items. If you use joists to support the extra weight, you can hang up to 30 pounds on the drywall ceiling.
How much weight can joist hold?
That means the joists can support a minimum of 40 pounds per square foot live load. Though, by consulting the 50 pounds per square foot live load/10 pounds per square foot dead load table, you can see the joists’ span would need to be reduced to 11 feet 11 inches to support heavier weight safely.
How do you hang something heavy from the ceiling without a stud?
Install blocking between a pair of ceiling joists to hang a heavy object between them. The blocking can be a piece of two-by-six lumber that fits exactly between the joists. Screw it to the joists with metal corner brackets and 1-inch screws. Screw a hook into the block to hang a plant or other heavy object.

Does drilling into a stud weaken it?
Only a small fraction of the stud is necessary for the bearing strength of the wall. Every plumbing and electrical run in your house goes through much larger holes drilled through studs. If your cabinet is solid, your stud is fine. As long as you didn’t split the stud, I don’t think it’s an issue.
How do I stop my ceiling from drilling through wires?
“One common rule is to avoid drilling around light switches and sockets, as the electrical wires can go horizontally and vertically around these fixtures,” Williams explains. “You can also get an idea of where wires and pipes run by looking in the attic and basement to see where they go up or down through framing.”
