Rundskruv

Rundskruv is a type of fastener characterized by its round head. This head shape is common across various screw types and is designed to sit flush with or slightly proud of the surface it is fastening into. The top of the round head is typically flat and may contain a drive recess such as a slotted, Phillips, or Torx head for insertion and removal. The underside of the head is usually countersunk or beveled to provide a bearing surface against the material.

The shaft of a rundskruv can be threaded along its entire length or partially, depending on the specific application. The thread pitch and diameter vary widely to accommodate different materials and load requirements. These screws are manufactured from a range of materials, including steel, stainless steel, brass, and aluminum, to suit environmental conditions and strength needs.

Rundskruv finds application in numerous industries, including woodworking, metalworking, and general construction. Their versatility allows them to be used in joining wood pieces, attaching hardware, securing metal components, and in various assembly processes. The specific type of rundskruv used will depend on the material being fastened, the required holding power, and aesthetic considerations. While the term "rundskruv" itself is Swedish for "round screw," it is often used generically to refer to screws with a round head profile in various contexts.
