Specifications:
The document provides specifications for Woodcert inserts with Head Type D, detailing various part numbers, thread sizes, lengths, and dimensions. Key dimensions include the thread size (M4 to M10), length (7.0 to 25.0 mm), and other critical measurements such as D1, D2, D3, and AK.

Procedures:
Woodcert inserts are installed by screwing them into the parent material using a hexagon driver or Allen key. The thin flange of the insert sinks flush with the substrate, providing a larger mounting surface area.

Applications:
These inserts are commonly used in furniture, shopfitting, and rotational mouldings, offering strong fixing into soft wood and composite materials.

Materials and Finishes:
The inserts are available in Zamac Zinc Clear (Code 60) and Zamac Zinc Yellow (Code 40).

Recommendations:
To specify an insert, use the format: Series No / Part No / Finish Code (e.g., 20130 M510 60). Designers are advised to request samples to ensure the suitability of the specification for their specific application.
