All About
Kreg Pocket Hole Screws.

Choose the right Kreg pocket hole screws to get the best result for each of your woodworking projects.

The Kreg Screws are made with a self-tapping auger bit, which means the screw acts like a drill bit by making the hole it is going into. This means that you do not have to predrill a hole in the 2nd piece, nor do you have to make it line up perfectly with your hole in the first piece. So, you can drill one hole, line up the pieces, and then screw them together with the Kreg pocket hole screws.

Materials Used to Manufacture the Kreg Pocket Hole Screws.

Kreg makes its screws from high quality, case hardened steel. That, plus the engineered custom head and the shank size, almost eliminate the possibility of breaking the screw.

The Kreg screws are also coated with a dri-lube finish. This coating resists oxidation and reduces the torque needed to drive the screws.

The deep square drive in the head of the Kreg screws prevents the head from getting stripped, also called 'cam out". The square drive also allows you to use more force in connecting each pocket hole joint.

There are Two Types of Heads for the Kreg Pocket Hole Screws.

The head that you will use the most is the flat washer head, called the Maxi-Loc head. This head will stop the screw at the bottom of the pocket hole to make sure your screw is not overdriven, and to keep your pocket hole joint as strong as possible.

The second type of head is the pan head, which is a bit smaller than the washer head. This head should be used when joining two hardwood pieces. Because the pan head is smaller, it is also easier to hide the screw in the pocket hole. Also, the shank is narrower to keep the hardwood from splitting. 

There are Two Types of Threads for the Kreg Screws.

These screws will have either a fine thread, or a coarse thread.

You will want to use the fine thread screws for hardwoods like: walnut, cherry, birch, ash, maple, oak and hickory. The fine thread screws reduce splitting in hardwoods.

The coarse thread screw is the one you will use most of the time. It is designed to make a strong pocket hole joint in softer materials. You will use this thread in: plywood, particle board, MDF, Melamine, pine, cedar, fir, spruce, butternut, poplar and aspen.

Kreg Screws are Available in Various Lengths.

The plans on 'Start With Free Woodworking' will give you the right length screw for each of the pocket hole joints on that project. But, if you are planning your own wood working project, the following chart will help you decide which screw length you will need. This chart can also be found on each box of Kreg pocket hole screws.

The Kreg Jig K5 comes with a "Screw-Length Selection Chart" that fits inside the cover of one of the wing extensions.  It is great to have the chart immediately available whenever you use your Kreg Jig!

Material ThicknessScrew
1/2" (13 mm) 1" (25 mm)
5/8" (16 mm) 1" (25 mm)
3/4" (19 mm) 1 1/4" (32 mm)
7/8" (22 mm) 1 1/2" (38 mm)
1" (25 mm) 1 1/2" (38 mm)
1 1/8" (29 mm) 1 1/2" (38 mm)
1 1/4" (32 mm) 2" (51 mm)
1 3/8" (35 mm) 2" (51 mm)
1 1/2" (38 mm) 2 1/2" (64 mm)

The length of these screws are measured from the bottom of the head to the tip of the screw.

There are Three Types of Kreg Pocket Hole Screws.

The Kreg screws that are zinc coated are the ones you will use for indoor projects, where moisture is not normally a big problem.

Kreg's Blue-Kote screws have 3 anti-corrosion layers that make them suitable for all indoor applications, as well as some outdoor projects.

The stainless steel screws should be used for all treated lumber projects, as well as, all maritime projects.
