Screw connector Wkręt-met WK-DS85 — spiral dowel connector, model WK-DS85

Wkręt-met WK-DS85 is a spiral dowel screw connector engineered for mechanical joining of wood and composite components. Designed to create strong, removable joints, the WK-DS85 provides a compact threaded dowel solution for furniture assembly, carpentry and repair tasks where alignment and clamping of panels and parts is required without welding or adhesives.

Advantages

The spiral dowel design ensures reliable thread engagement in wood and engineered panels, delivering consistent withdrawal and shear resistance. Its threaded body permits repeated assembly and disassembly while maintaining alignment, reducing the need for permanent adhesives. The compact form factor minimizes visible hardware and allows installation in narrow edges or confined spaces, making it suitable for cabinetry and furniture frames.

Suitable for

• Furniture assembly and knock-down fittings
• Cabinet construction and panel alignment
• Repair and refurbishment of wooden components
• Carpentry tasks requiring removable mechanical joints

Key specifications

• Connector type: spiral dowel screw (threaded dowel)
• Material: metal suitable for load-bearing mechanical fastening (zinc-plated or similar finish typical for the model)
• Intended substrates: solid wood, plywood, MDF, particleboard and composite panels
• Function: creates aligned, removable mechanical joints with threaded engagement
• Installation profile: compact cylindrical body for edge or face mounting in panels

How to use

Drill a pilot hole of the appropriate diameter and depth in the component according to panel thickness and the connector length. Insert the spiral dowel connector and drive it in using an appropriate tool until the connector is flush or at the recommended insertion depth. Align the mating part and insert the corresponding screw or threaded mating element; tighten to achieve the required clamping force without over-torquing. For disassembly, reverse the process to remove the screw and extract the dowel if necessary.

Usage recommendations

Choose pilot hole diameter and insertion depth based on substrate density and panel thickness. Use hand or power tools with torque control to avoid splitting thin edges. When working with particleboard or MDF, consider shorter insertion depths and support back faces to prevent breakout. For repetitive assembly, inspect the connector engagement and mating threads periodically and replace connectors showing wear.
