kierrelevyistä

Kierrelevyistä, or screw plates, are metal components used to join or reinforce wood or other materials. They typically feature a flat metal surface with one or more holes for fasteners, such as screws or bolts. Often, the holes are countersunk, allowing the fasteners to sit flush with the surface of the plate for a smoother finish and to prevent snagging. Kierrelevyistä can also incorporate threaded inserts, commonly known as T-nuts or threaded bushings, which provide a strong and reusable connection point for screws. These threaded inserts are embedded into the material being joined, and the screw then threads directly into them.

The primary purpose of kierrelevyistä is to distribute stress over a larger area, thereby strengthening a joint and preventing materials from splitting or pulling apart. They are frequently used in furniture construction, cabinetry, and various DIY projects where durability and a secure connection are important. Different types of kierrelevyistä exist, varying in size, shape, material (such as steel, brass, or aluminum), and the number and type of threaded inserts they contain. The selection of a particular kierrelevy depending on the load requirements, the type of materials being joined, and the desired aesthetic. Installation usually involves inserting screws through the plate's holes into the material or, if threaded inserts are present, screwing into the plate itself.
