How many screws on drywall with framing 24" O.C.?

Can anyone tell me what code is on this? How far apart should the screws be when the framing is 24" O.C.? Also, how long should the screws be on the first layer of 5/8" and second layer of 5/8" drywall. Thanks!!

i think full schedule is every 8 inches around the edge and every 12 in the middle.

Check with your local building department. They may have a handout for this question. In my jurisdiction, the schedule differs for drywall screws vs. nails. Codes vary from place to place. The screw length question depends on whether you are using steel or wood studs. Rod wrote this on my thread:

. . . you want more than 1" of penetration - I would consider 1 3/8" absolute minimum - and 1 1/2 to 1 5/8" preferable.

Note that this was for ceiling -- perhaps less penetration may be OK for walls...? :roll: Bottom line, though, check with your local building department, as they are the experts on what is required there. --Keith :mrgreen:
