This video was created by Jeff from Today’s Craftsmen. It’s a detailed guide to help woodworkers understand which screws to use for different materials, joints, and applications.
While screws might seem like a small detail, they can make or break the quality and longevity of your project. Jeff breaks down the types, sizes, and features that matter most—and shares mistakes to avoid when fastening wood.

Understanding the Basics
There are three main types of screws commonly used in woodworking: construction screws, pocket screws, and specialty fasteners. Each serves a different purpose and performs best under certain conditions.
Construction screws are ideal for general framing and assembly. Pocket screws are used for hidden joinery, especially in furniture and cabinetry. Specialty screws come into play for specific wood types, finishes, or structural needs.
Construction Screws
Construction screws are versatile and frequently used in both framing and cabinetry. Jeff recommends sizes like 1¼” and 1½”, depending on the material thickness and type of joint.
The shorter 1¼” screws are best for joining two pieces of ¾” material, as they reduce the risk of blowout. For butt joints and deeper assemblies, 1½” screws offer better grip and holding power.
Many of these screws have a Type 17 tip, which helps them drill into wood without pre-drilling. This can save time and reduce splitting, especially in softwood projects.
Pocket Screws
Pocket screws are perfect for creating strong, hidden joints in cabinetry and furniture. They come in different thread types—coarse for softwoods like plywood, and fine for dense hardwoods.
Jeff explains that coarse-thread screws grip plywood well without needing pilot holes. In contrast, fine-thread screws are better suited for hardwoods, reducing the risk of splitting and improving joint strength.
One of the biggest advantages of pocket screws is how they allow the screw heads to stay hidden, giving your project a clean, professional finish. They also simplify assembly and minimize the need for clamps.
Matching Screws to Materials
Choosing the right screw often depends on the material you’re using. Hardwoods like maple or oak require fine-thread screws that bite into dense grain without damaging it.
For softer woods or engineered materials like plywood, coarse-thread screws provide stronger holding power. Matching screw type to material ensures longer-lasting joints and fewer installation issues.
Head Types and Countersinking
The screw head design affects both the look and function of your assembly. Bugle head screws, which are common in construction, naturally countersink into wood for a smooth finish.
While many bugle head screws have self-countersinking nibs, Jeff still recommends using a countersink bit for clean, flush finishes—especially when appearance matters.
This extra step not only improves aesthetics but can also reduce surface damage and tear-out during driving.
Drive Types: Phillips vs. Torx
Screw drive type can make a huge difference in user experience. Traditional Phillips heads are still widely used, but they are prone to camming out—when the driver slips and damages the screw or material.
Jeff highlights Torx screws as a better option. Their star-shaped heads provide more contact between the screw and driver, reducing cam-out and allowing for more consistent torque.
Square drive screws are also common in pocket hole applications. These offer decent grip and are less likely to strip than Phillips, but still not as reliable as Torx for heavy-duty work.
Where to Buy Quality Screws
Using better-quality fasteners pays off in cleaner assemblies and fewer frustrations. Jeff recommends choosing screws from trusted brands that offer consistency, clear labeling, and proper sizing.
One example he mentions is a Georgia-based supplier that offers screws with a T20 Torx head across multiple sizes. This means fewer driver swaps during assembly, making your workflow more efficient.
Common Mistakes to Avoid
Jeff also shares a few common mistakes woodworkers make with screws—and how to avoid them.
One of the most frequent errors is using screws that are too long. This can lead to breakouts, sharp ends poking through, or even injuries. On the other hand, screws that are too short may not hold under stress.
Another issue is skipping the pilot hole. While some screws are self-drilling, hardwoods often still require pre-drilling to prevent splitting. This is especially true when working near edges or in more brittle materials.
Tips for Better Fastening
To get better results with screws in your woodworking projects, keep these tips in mind:
- Match the screw type and thread to the wood you’re using.
- Use Torx screws for better grip and cleaner driving.
- Pre-drill when working with hardwoods, even if the screws are self-tapping.
- Countersink when you want flush finishes or plan to plug screw holes later.
- Buy from reputable suppliers to avoid inconsistent quality or poorly threaded fasteners.
A Small Detail with Big Impact
Screws may not be the flashiest part of woodworking, but choosing the right ones can dramatically improve the quality of your builds. They affect everything from strength to appearance, and even ease of assembly.
Jeff’s overview offers a clear, practical guide that’s especially helpful for beginners but still valuable for experienced woodworkers.

Matt’s Take
These are my personal thoughts and tips based on my own experience in the shop. This section is not written, reviewed, or endorsed by the original creator of this project.
Quality screws are one of those shop investments that really pay dividends over time. I’ve noticed that stepping up from basic construction screws to better fasteners makes a noticeable difference in both the building process and the final result. The extra few dollars spent on Torx drive screws is worth it just for the reduced frustration alone – there’s nothing worse than a stripped screw head when you’re trying to maintain momentum on a project.
The material matching aspect Jeff covers is spot-on and something I see newer woodworkers struggle with. Dense hardwoods like maple will split if you’re too aggressive, even with self-drilling screws. I always keep a set of pilot bits handy because pre-drilling is often the difference between a clean joint and a ruined piece. For pocket holes especially, taking that extra moment to drill properly saves headaches down the road.
One thing worth adding to your screw toolkit is a good countersink bit set. Even self-countersinking screws benefit from a proper countersink, especially if you’re planning to plug the holes later. The clean, consistent depth you get with a dedicated bit makes plugging much easier and gives you that professional look Jeff mentions.
Storage is another consideration – I keep my most-used screws organized in small containers with clear labels. When you’re in the middle of assembly, being able to quickly grab the right 1¼” coarse-thread pocket screw without hunting through mixed boxes keeps your workflow smooth.
