Træbolter

Træbolter are a type of fastener commonly used in woodworking and construction. They are essentially bolts designed specifically for use with wood. A key characteristic of a træbolter is its coarse threads, which are optimized for gripping into the fibers of wood. This allows for a strong and secure hold without the need for pre-drilled nuts in many applications.

Træbolter typically consist of a threaded shaft and a head. The head can come in various shapes, such as hex (hexagonal), carriage (round with a square neck), or lag (often with a hexagonal or square head). The choice of head style often depends on the specific application and the desired aesthetic. Hex-head træbolter are common for applications requiring significant torque, while carriage bolts are used where a smooth, snag-free surface is desired.

The installation of a træbolter usually involves drilling a pilot hole into the wood. The size of the pilot hole is crucial; it should be smaller than the bolt's shank but large enough to allow the threads to engage effectively without splitting the wood. Once the pilot hole is drilled, the træbolter is driven into the wood using a wrench or socket, which engages with the head.

Træbolter are employed in a wide range of projects, including furniture making, building decks, constructing fences, and assembling timber frames. Their ability to create strong connections in wood makes them a reliable choice for structural and decorative purposes. Compared to nails, træbolter offer greater holding power and can be tightened or loosened if necessary.
