Timber frame construction has been used for centuries to build durable and beautiful structures. One of the key features of timber frame construction is the use of timber frame connectors and fasteners to join the wooden beams together. In this post, we will discuss the different types of timber frame connectors and fasteners used in construction.

Mortise and Tenon

Mortise and tenon joints are one of the oldest and most reliable timber frame connectors. A mortise is a hole or recess cut into a beam, and a tenon is a projection on the end of another beam that fits into the mortise. This joint is often secured with a wooden peg, which is driven through a hole in the side of the tenon and into the mortise. This creates a strong, durable joint that can withstand the test of time.


Dovetail joints are another popular type of timber frame connector. They are similar to mortise and tenon joints, but instead of a straight tenon, the end of the beam is cut at an angle to create a wedge shape. The mortise is cut to match the shape of the wedge, and the two pieces are fitted together tightly. This joint is often used for decorative purposes, as the wedge shape creates an attractive pattern.


Scarf joints are used to join two beams end-to-end to create a longer beam. The ends of the two beams are cut at an angle, and then the two pieces are fitted together and secured with a wooden plate or metal bracket. Scarf joints are often used in timber frame construction to create long roof beams or floor joists.

Steel Plates and Bolts

Steel plates and bolts are commonly used to connect timber frame structures to their foundations. Steel plates are attached to the bottom of the wooden beam, and then bolts are used to secure the plate to the foundation. This type of connector is often used in commercial and industrial buildings where a strong, durable connection is required.

Timberlok Screws

Large, powerful screws called Timberloks are used to join wood beams together. They are made to be installed quickly and easily without the need for pre-drilling. In DIY projects and home building, Timberlok screws are frequently used.

Timber Connectors

Metal brackets called timber connectors are used to connect wooden beams together. They are available in a range of sizes and shapes, such as T-, L-, and U-shaped brackets. In contemporary timber frame construction, timber connectors are frequently used to quickly and simply connect the beams.

Timber Frame Pegs

To hold mortise and tenon joints together, timber frame pegs are used. They are usually made from hardwoods like oak or maple and are sized to fit the joint's required length and diameter. In conventional timber frame construction, timber frame pegs are frequently used.

There are many different types of timber frame connectors and fasteners available for use in construction. Each type has its own unique advantages and disadvantages, and the choice of the connector will depend on the specific requirements of the project. Whether you are building a traditional timber frame structure or a modern commercial building, choosing the right connectors and fasteners is essential to ensure a strong and durable structure.
