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.

You will want to choose a countersink that is larger than the bolt size of the hole. Countersink diameter = 1.5 x Bolt Size Hole Diameter. Example: 1/4″-20 Bolt – Multiple the diameter (. 250) x 1.5 = 0.375.

How deep is a stud?

With studs generally 16 inches on center, you can also do calculations by measuring from a corner of the room. Now, all rooms aren’t built in numbers divisible by 16, so you are likely to have a stud that is less than 16 inches from one corner.
