When it comes to carpentry, there are distinctions that the average layperson might never have heard of or even noticed. For example, not all screws are created equal–the type of screw you use depends on the situation. For example, when the screw is to be hidden out of sight–in a “pocket“–then a pocket screw is called for. Here, we’ll help you understand what distinguishes a pocket hole screw from the rest, then help you decide which brand will best suit your needs.
What is a pocket hole screw?
A pocket hole screw is designed to act as a joint between two boards, both of which have had angled “pockets” drilled into them to allow the screw to remain out of sight. While the screw needs to be exceptionally strong in order to secure the boards at the joint, the process is actually quite simple to learn. All you need is a pocket hole jig for drilling holes on your wood, after that secure them with pocket screws.
What do pocket hole screws look like?
At first glance, there’s little to distinguish a pocket hole screw from any other screw. The head is generally flat-bottomed, with a square drive to prevent slippage. The shank is smooth for about half the length, at the spot where the boards will be held together. The “active” portion of the shaft ends in a sharp self-drilling tip that’s capable of drilling its own hole without splintering the wood.
What’s the difference between pocket hole screws and regular screws?
What is meant by “course thread” versus “fine thread,” and which should I use?
What’s the difference between a washer-head and a pan-head pocket hole screw?
Washer-head screws are the most popular for all kinds of application. Featuring a large flat bearing surface with the top is usually indented, it provides the strongest joint possible.
Pan-head screws feature a flat bearing surface and cylindrical sides. It has smaller head size and shank diameter, which work wonder with harder wood and prevent splitting in thin board.
Sizes and Lengths
Following is a list of different sizes and lengths, along with recommendations on which screw to use depending on the thickness of your material. Note that the job will be much easier if the two boards share the same thickness. If one is noticeably thicker than the other, you’ll probably want to sand it down before beginning work. Here is the size chart for pocket hole screws:
|Thickness of Board||Screw Length|
|1/2″||3/4″ or 1″|

any suggestions for a 3/4″ coarse thread screw for use in pocket hole work on 1/2″ softwood or ply material? Kreg only makes a fine thread in the 3/4″ length
For a 1/2″ thick wood material, you can use screw from 3/4″ to 1″. I saw that Kreg has the Kreg SML-C1, which is a 1″ coarse thread screw that would work with your wood too. Hope this helps.
