Stiftpinnen

Stiftpinnen, also known as dowel pins or straight pins, are simple mechanical fasteners. They are typically cylindrical rods made of metal, such as steel, brass, or aluminum, though they can also be made from plastic or wood. The primary function of a stiftpinne is to provide precise alignment and secure joining between two or more components.

They are inserted into precisely drilled holes, which are often reamed to ensure a snug fit. The pin prevents relative movement between the joined parts, acting as a shear or locating element. In many applications, stiftpinnen are used in conjunction with screws or bolts, where they provide a stable reference point and prevent rotation or shifting of the assembled parts. Their simplicity and reliability make them a common choice in a wide range of industries, including automotive, aerospace, and manufacturing.

Stiftpinnen come in various lengths and diameters, and some may feature knurled surfaces or threads to enhance their holding power in softer materials. The selection of the appropriate stiftpinne depends on factors such as the required load-bearing capacity, the materials being joined, and the operating environment. Their ease of use and cost-effectiveness contribute to their widespread adoption in mechanical design and assembly.
