How to Select the Correct Pocket-Hole Screw?

Pocket-hole joinery is a popular and effective method for assembling woodworking projects quickly and securely. Using the right pocket-hole screws is crucial to ensure the strength and longevity of the joint. Here is a detailed guide on selecting the appropriate pocket-hole screws for your projects, tailored to the considerations and options offered by the Fullerkreg brand.

Step 1: Determine the Thickness of Your Material

The first step in selecting the right screw is to measure the actual thickness of the wood you are using. Wood sold in stores often has nominal dimensions that differ from actual dimensions, so it’s important to use the real measurements when choosing screws. This ensures that the screw length appropriately matches the thickness of the wood to avoid either too shallow or too deep penetration, which could compromise the joint.

Step 2: Choose the Correct Screw Length

The correct screw length is crucial for creating a strong joint. If the screw is too long, it might protrude from the wood, while a screw that is too short may not hold effectively. For instance, for 3/4″ thick materials, a 1-1/4" long screw is generally suitable. As the material thickness increases, so should the screw length. Fullerkreg offers a variety of lengths suitable for different material thicknesses.

Step 3: Select the Appropriate Thread Type

The type of wood you are working with will determine whether you should use coarse or fine threads:

Coarse Threads: Ideal for softwoods like pine, cedar, and materials such as plywood and MDF. Coarse threads are larger and provide better holding power in these less dense materials.

Fine Threads: Best for dense hardwoods such as oak, maple, and cherry. Fine threads are necessary to avoid splitting these harder woods, as they provide better grip at a smaller thread pitch.

Step 4: Consider the Screw Head Type

Fullerkreg pocket-hole screws typically come with a washer-head design which is crucial for pocket-hole joinery. This design helps distribute the clamping force evenly and prevents the screw from pulling through the wood. This is particularly important when working with softer woods or thinner materials.

Step 5: Decide on the Screw Coating Based on Project Location

The environment where the project will be used also affects the choice of screw coating:

Indoor Projects: Zinc-coated screws are usually sufficient for indoor projects, including those in moisture-prone areas like kitchens and bathrooms.

Outdoor Projects: For outdoor projects, consider screws with specialized coatings like Blue-Kote™ from Fullerkreg, which offers enhanced resistance against corrosion and weathering. For extreme conditions, stainless steel screws provide the highest level of durability and corrosion resistance.

Step 6: Do I really need Kreg Pocket-Hole Screws?

Yes. With all the kinds of screws you can buy in home centers, you might ask yourself if you really need to use Fullerkreg Pocket-Hole Screws to build your projects. Why choose them over wood screws, drywall screws, or deck screws?

The answer is that Fullerkreg Pocket-Hole Screws are engineered for pocket-hole joinery, with specific features that ensure the best performance.


Choosing the correct pocket-hole screw is essential for ensuring the durability and structural integrity of your woodworking projects. By considering the material thickness, wood type, screw length and diameter, head type, and environmental exposure, and using the resources provided by Fullerkreg, you can select the ideal screw for any project you undertake. Remember, the right start with the right screw sets your project up for success. Happy building!
