Kreg® Screws

Kreg® Screws

Kreg® offers a wide selection of specialized screws. Whether its indoor or outdoor applications, hardwoods or softwoods, we've got just the screw you're looking for.

Choosing a Screw

Kreg® Screws are available in several different types, each with unique qualities that optimize performance in specific applications. Once you understand these qualities, it’s easy to choose the correct Kreg® Screw. In this video, we take a few minutes to tell you about each type of screw, and we suggest a few simple guidelines you should consider to pick the best screw for everything you build.

Kreg Screw® Qualities

Composition:

Zinc screws are recommended for a wide variety of indoor projects where moisture is not a concern.

Blue-Kote™ screws are the best choice for damp or wet applications, and work with treated lumber.

Stainless screws are designed for use in extreme environments that are exposed to moisture and corrosive elements.

Thread Style:

Coarse-Thread screws are recommended for use with softwoods like cedar, pine, fir, etc.—as well as for sheet goods such as plywood and MDF—that are soft and not very dense. Coarse screws have deep, aggressive threads that bite into those soft fibers to ensure solid holding power.

Fine-Thread screws are the preferred choice for hardwoods like cherry, maple, oak, etc. that are hard and dense. Fine threads are less aggressive, so they’ll drive without splitting, but these screws have a higher number of threads per inch to ensure great holding power.

Head Style:

Maxi-Loc screws are a great choice for the majority of applications. These Kreg® Screws have a large head that provides maximum bearing surface as the screw pulls tight in the pocket.

Pan-Head screws are perfect for dense hardwoods and for 1/2"-thick stock. Their smaller shank reduces the chance of splitting, and the smaller head allows them to fit places where space is limited and/or tight pocket-hole spacing is desired.

Composition

Steel Kreg® Screws are case hardened—a process that forms a tough outer shell (or case) to make the screw durable, but keeps the core softer to prevent the screw from becoming brittle. That means you get the best of both worlds: a strong screw that won’t snap. Kreg® Screws are available in three finishes.

Zinc-coated screws are recommended for a wide variety of indoor projects where moisture is not a concern.

 

Blue-Kote™ screws are the best choice for damp or wet applications. They feature 3 anti-corrosion layers, making them perfect for outdoor use and high-moisture environments.

Stainless-steel Kreg® Screws are designed for use in extreme applications, excessive exposure to salt water, and other exceedingly-corrosive environments, such as fastening ACQ-treated lumber.

Head Style

Ordinary woodworking screws and drywall screws have a head with a conical shape on the underside. The head on a Kreg® Screw is perfectly flat on the underside to mates perfectly with the flat bottom in a Kreg® pocket hole. When you drive a Kreg® Screw into the pocket hole, this flat shape applies force straight toward the screw tip, so it holds the joint tightly together without deforming the pocket, which could split the wood. Kreg® Screws are available in two head styles.

MAXI-LOC

Maxi-Loc screws are the Kreg® Screw of choice for the majority of applications. These Kreg® Screws have a large head that provides maximum bearing surface as the screw pulls tight in the pocket.



 

PAN-HEAD

The smaller head of Pan-Head Kreg® Screws makes them the preferred choice for extremely hard woods and for 1/2"-thick stock. Pan-Head screws also feature a smaller shank diameter that reduces the chance of material splitting. Pan-Head screws work with Kreg® standard and Micro-Pocket™ Drill Guides.

Screw Length

Selecting the correct screw length is the most important consideration when choosing a Kreg® Screw. We suggest using the screw lengths shown below when joining materials of the same thickness (such as joining 3/4"-thick material to 3/4"-thick material). To help select the right screw length when joining materials of different thicknesses, our Screw Selector Wheel is a handy tool.

The threads on a Kreg® Screw stop partway up the screw shank, which leaves a smooth area below the screw head. When the screw is driven in, the threaded portion grabs into the workpiece you’re attaching to, pulling the screw in. The other piece glides freely over the unthreaded part of the screw, allowing that piece to pull tightly against the mating piece—without unnecessary threads that can actually push the joint apart.

Thread Style

Kreg® Screws are available in two different thread types—coarse thread and fine thread—to match the screw-holding abilities of different types of woods. Both thread types feature a self-tapping tip that “drills” its own hole, so the screw drives in quickly and easily without splitting the wood—and without requiring a pilot hole in the mating workpiece.

Fine Thread 

Fine-thread screws are the preferred choice for hardwoods that are hard and dense. These threads are less aggressive, so they’ll drive without splitting, but these screws have a higher number of threads per inch to ensure great holding power.

Coarse Thread

Coarse-thread screws are recommended for use with softwoods—as well as for sheet goods such as plywood and MDF—that are soft and not very dense. Coarse screws have deep, aggressive threads that bite into those soft fibers to ensure solid holding power.
