Wood fasteners are selected based on three criteria: the connection load, the dimensions of the joined elements, and the conditions in which the structure will operate. Options include screws, bolts, and nails, as well as steel sheet connectors such as angle brackets, perforated plates, joist hangers, and nail plates. Each of these fasteners has a different application, transfers forces differently, and requires a different installation method. Carpentry connections made using the wrong fastener lose load-bearing capacity even if the connector itself is of the highest quality. Practical experience shows that most connection problems do not stem from a weak fastener, but from a good fastener used in the wrong place or installed improperly (not securely enough). <\/p>\n

Wood Fasteners and Their Basic Classification<\/strong><\/h2>\n

Wood fasteners are divided into two groups. The first consists of dowel-type fasteners that pass through the wood or become wedged within it. The second consists of sheet metal connectors that distribute forces over a larger area and themselves require fastening with nails, screws, or a press. According to a Silesian University of Technology study on modern connectors and fasteners<\/a>, dowel-type fasteners include nails, screws, bolts, pins, and staples, with minimum distances between them defined by Eurocode 5 (the PN-EN 1995-1-1 standard). <\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Screws and Bolts as Basic Wood Fasteners<\/strong><\/h2>\n

Screws work best where speed of connection is important, while bolts are used where the connection must transfer large forces or be demountable. Both fasteners differ in their principle of operation. The screw thread wedges into the wood, whereas a bolt passes through a hole and clamps the elements together by tightening a nut. <\/p>\n

Wood Screws<\/strong><\/h2>\n

Self-drilling wood screws are most commonly used; thanks to their shaped tip, they do not require a pilot hole. Three features are important when choosing. <\/p>\n
