inzetstuk

An inzetstuk is a piece designed to be inserted into another part to create a precise fit, fill a space, or provide a mounting, alignment, or bearing surface. It is a generic Dutch term used across crafts and industries to describe insert components that are intended to be placed within or against another part. Depending on the application, an inzetstuk may take the form of a spacer, shim, plug, bushing, liner, collar, or adapter, and it may be made from wood, metal, plastic, or composite materials to suit mechanical, architectural, or decorative needs.

In carpentry and furniture making, inzetstukken are used to adjust dimensions, reinforce joints, hide fasteners, or receive hardware. In cabinetry, inserts can help align doors or panels and accommodate hardware fittings. In metalworking and machine construction, inzetstukken function as interchangeable inserts that adapt tools and fixtures, center workpieces, or provide wear-resistant bearing surfaces. They may also be used as sacrificial inserts in dies, molds, or jigs to extend tool life or simplify replacement.

Etymology: The word inzetstuk is formed from inzetten (to insert) and stuk (piece). It is a generic term and its exact meaning is defined by context and industry.
