Another type of screw that can be used in woodworking are bolts and nuts. The bolt is a rod that sticks through both of the wood pieces, to be fastened at the end by tightening the nut.

They are a durable and easy to disassemble mechanical connection. They are available in different types of metal (for a more extensive environmental profile, check galvanized steel, stainless steel and brass screws).

Bolts and nuts can get damaged when they are forced together, or when they are exposed to water extensively. In case of stainless steel, the oxide layer (formed by the chromium) can be scraped off. Galvanised bolts can loose their zinc layer and go rusty. Both cases will make it very difficult to remove the nut.
