Head Style
The washer head (Maxi-Loc) screw is our most popular head style as it provides the largest amount of surface area to seat firmly in the bottom of the pocket. Available in both fine or coarse thread, this head style is highly recommended if the material the pocket is drilled into is soft such as plywood or pine. The large washer head assures that the screw is not overdriven in the bottom of the pocket.

The second available head style is the Pan Head. The Pan Head is slightly smaller in both head and shank diameter than the washer head screw and is a good alternative to the washer head screw if both
mating workpieces are made of extremely hard woods. The pan head style is also of benefit in the 1" length as it allows one to join 1/2" material to 1/2" material and easily seat the screw head below flush.

Screw Length

There are four thread lengths most commonly used in pocket hole joinery, they are 1", 1.1/4", 1.1/2" and 2.1/2". Choosing the correct screw length depends on the setting of your jig and the depth at which you drill the pocket hole. In most 1/2" to 1/2" applications you will want to use a 1" screw. When joining 3/4" to 3/4" stock, a 1.1/4" screw is standard. If you are joining 1.1/2" to 1.1/2" stock the 2.1/2" screw is preferred.
