Boutetiers

Boutetiers are a type of fastener primarily used in the construction of wooden structures, particularly in traditional joinery. They are characterized by their distinct shape, which typically features a long, tapered shank and a broad, flat head. This design allows them to be driven deeply into wood, providing a strong and secure hold. The broad head helps to distribute the clamping force over a larger surface area, reducing the risk of the fastener pulling through the wood. Boutetiers are often made from durable metals such as iron or steel to ensure longevity and resistance to corrosion.

Historically, boutetiers were a common choice for assembling beams, rafters, and other structural elements. Their effectiveness in creating robust joints made them indispensable in timber framing and carpentry before the widespread adoption of modern screws and nails. While less common in contemporary construction, they can still be found in restoration projects of historic buildings or in specialized applications where their unique holding power is desired. The process of driving a boutetier requires a hammer and a suitable setting tool to ensure it is properly seated without damaging the wood. The term itself is of French origin, reflecting their historical prevalence in various European woodworking traditions.
