durchgehendHolzgewinde

DurchgehendHolzgewinde (literally “continuous wood thread”) refers to a type of screw thread that runs uninterrupted along the entire length of a wooden fastener, as opposed to the more common partial or segmented threads found on many wood screws. The design provides a uniform engagement surface, allowing the fastener to distribute load more evenly throughout the wood and to achieve higher withdrawal resistance.

The concept originated in the early 20th century, when manufacturers sought to improve the holding power of wooden fasteners used in construction, furniture and timber framing. By machining a continuous thread along the shank, the screw can be driven into solid wood, laminated boards or engineered timber without the need for a pilot hole in many cases, reducing installation time.

Manufacturing processes for durchgehendHolzgewinde typically involve coldheading or hot‑forming of steel wire, followed by thread rolling or precision machining to achieve the continuous profile. The thread geometry is usually a coarse, wide‑flanged form (often designated as “V‑type” or “square” threads) to maximize shear area within the wood fibers. Surface treatments such as zinc plating, hot‑dip galvanizing or phosphating are applied to enhance corrosion resistance.

Key advantages include superior pull‑out strength, reduced splitting of the material, and consistent torque characteristics. Limitations relate to higher production costs compared to standard wood screws and the requirement for compatible pilot holes in very dense or brittle woods to avoid excessive insertion torque.

Standards governing durchgehendHolzgewinde are found in DIN V 4505 (Germany) and ISO 3865 (international), which specify dimensions, thread pitch, material grades and testing methods. The fastener is widely used in timber construction, portable scaffolding, and heavy‑duty furniture assembly where reliable, long‑term joining is essential.
