staafpunten

Staafpunten is a Dutch term that refers to the tips or ends of rod-like components. The word is formed from staaf (bar, rod) and punt (point). In practice, staafpunten are small features designed to form an interface between parts, guide movement, or provide a wear-resistant contact point. They are found in many industries and can vary widely in form and material.

Common shapes include conical tips for centering and easing entry; hemispherical tips to distribute load; threaded ends to accept nuts or fittings; and knurled or smooth ends for grip or alignment in sleeves. Materials range from carbon steel and stainless steel to carbide and high-performance polymers, selected for hardness, toughness, and compatibility with connected components.

Functions of staafpunten include guiding and aligning parts, centering shafts or dowels, transferring loads, and serving as wear-resistant contact points. In addition, plastic or ceramic variants may provide electrical insulation or reduced friction in specific applications.

Context and usage vary by industry. In metrology, tips on probes and styluses for coordinate measuring machines can be described as staafpunten. In mechanical assemblies, the end of a bar or dowel with a staafpunt provides precise seating or alignment. In electrical testing, contact tips on test probes are sometimes referred to by this term. Because the term is context-dependent, its exact meaning is determined by the particular technical field.
