Trykstift

Trykstift is a term used in Danish and Norwegian technical language to describe a pin designed to be pressed into a hole or into another part to locate, align, or secure components in an assembly. The word combinestryk (pressure) and stift (pin). In English-language engineering, related concepts include dowel pins, locating pins, or press pins; however, trykstift can cover several pin types within Nordic practice and does not refer to a single standardized component.

Function and use

Trykstift are employed in jigs, fixtures, stamping dies, mold tools, and automotive assemblies to maintain alignment during machining or to secure parts together by friction or a press fit. They can be solid or hollow and may be straight or slightly tapered. Common materials include hardened steel, stainless steel, or carbide for wear resistance. Installation is typically by pressing the pin into a predrilled bore with a press, or by other insertion methods that achieve the desired interference.

Variants and related concepts

Variations include locating pins, dowel pins, and spring or roll pins that provide some axial give or retention. The exact type designated as a trykstift can vary by industry and country, and the term is used more as a descriptive category than as a single standardized component.
