What Are Hex Wood Screws

Hexagonal wood screws , also known as hex wood screws, are a popular type of fastener used in woodworking, furniture making, and home repair projects. They come in various sizes, shapes, and materials, including steel, brass, and stainless steel. Today, we will discuss three common types of hexagonal wood screws: head wood screws, dowel screws, and self-tapping screws.

Basic Knowledge of Hex Wood Screws 

Structure of Hex Wood Screws

Hex head wood screws have a pointed tip, a cylindrical shank, and a threaded shaft. The head of a hex wood screw is hexagonal in shape, providing better grip and torque control.

Manufacturing Materials of Hex Wood Screws

Hex wood screws can be made of various materials, such as carbon steel, stainless steel, brass, and bronze. The choice of material depends on the application and the environment where the screw will be used.

Types of Hex Wood Screws 

Head Wood Screws

Hexagonal head wood screws are the most commonly used type of screw in woodworking. They have a pointed tip that helps them penetrate the wood and a threaded shaft that provides a secure hold. Hexagonal head wood screws are available in different lengths, diameters, and thread pitches, and can be used for a wide range of applications, such as building wooden structures, making furniture, and hanging shelves.

Dowel Screws

Hexagonal dowel screws, also known as hanger bolts or screw studs, have threads on both ends, making them ideal for connecting two pieces of wood or attaching furniture legs. One end of the screw has a wood screw thread, while the other end has a machine screw thread that accepts a nut or threaded insert.

Self-tapping Screws

Hex self-tapping screws, also known as sheet metal screws, have a sharp, pointed tip that can penetrate the wood and create its own threads without requiring a pilot hole. Hexagonal self-tapping screws are commonly used in projects where the wood is thin, such as building decks or fences.

How to Choose the Right Hex Wood Screw 

Selecting the Right Size

Choosing the right size screw is essential for ensuring a secure hold. The diameter of the screw should be equal to or slightly smaller than the diameter of the pilot hole.

Considering the Type of Wood

Different types of wood have different densities, which affects the type of screw that should be used. Hardwoods like oak and maple require stronger, larger screws than softwoods like pine and cedar.

Determining the Application

The type of application determines the type of screw that should be used. For example, hexagonal wood screws are suitable for general woodworking applications, while hexagonal dowel screws are used for connecting two pieces of wood.

Safety Precautions  For Hex Wood Screw

Using High-Quality Screws

Using high-quality hexagonal screws is essential for ensuring a secure hold and preventing accidents. Inferior quality screws may break or snap under pressure.

Using the Right Tools

Using the right tools is essential for ensuring the screw is installed correctly. Using the wrong size or type of screwdriver can strip the screw head or damage the wood.

Following Safety Procedures

When working with hexagonal wood screws, it’s essential to follow proper safety procedures, such as wearing eye protection and using a clamp to secure the workpiece.


In conclusion, hexagonal wood screws are an essential component of woodworking projects. The three types of hexagonal screws discussed in this article – head wood screws, dowel screws, and self-tapping screws – each have their unique properties and applications. Choosing the right screw for the job and using it correctly is essential for ensuring a secure hold and a successful and safe project. By considering factors such as the size of the screw, the type of wood, and the application, you can select the appropriate hexagonal wood screw for your project. Additionally, following safety procedures and using the right tools and high-quality screws are crucial for a successful and safe project. With the knowledge of the different types of hexagonal wood screws and the factors to consider when choosing the right one, you can confidently tackle your next woodworking project.
