Tukehti

Tukehti is a Finnish noun meaning a small support element used to stabilize, align or fill gaps between parts. In carpentry, furniture making, metalworking and construction, tukehti refers to a piece—often a short block or wedge—that bears the load or fixes components in place during assembly or adjustment. It is similar in function to a shim or bracing device in other languages.

Forms and materials: Tukehti can be wooden, plastic, or metal, and comes in various shapes, such as rectangular blocks for bearing surfaces or tapered wedges for leveling. It can be used to level furniture, align machine parts, space components, or prevent movement during soldering, gluing, or machining.

Usage and scope: It is typically used as a temporary or semi-permanent element. In some contexts a tukehti is fixed or pressed between parts; in others it's removable. The term appears in technical manuals, carpentry guidelines and workshop talk.

Etymology: Derived from tukea “to support”; the suffix -hti forms a noun indicating device or means. Related terms include tuki “support” and tukeminen “supporting.”
