INSERT NUTS TYPE D are headed hex-drive screw-in threaded inserts designed for wood, furniture panels, and other materials that need a controlled insertion depth and a clean pilot hole finish.

The key structure of this product is the sealing flange. During installation, the flange helps limit how deep the insert enters the material and leaves a tidier opening around the pilot hole. This makes Type D inserts useful for furniture factories, panel product manufacturers, cabinet makers, and hardware distributors that care about both fastening strength and finished appearance.

The external self-tapping thread is designed to improve resistance against torsion and vibration pull-out. After the insert is installed, the internal thread provides a stable metal thread for matching screws or bolts.

This page should focus on Type D structure, headed hex-drive installation, self-tapping external thread, sealing flange, and corrosion-resistant coating. It should not be written as a general wood insert nut page.

Where Type D Inserts Are Used

Type D insert nuts are commonly selected for wood furniture, cabinet panels, display fixtures, hardware kits, panel connection projects, and furniture parts that require repeatable screw or bolt fastening.

Because the flange helps keep the pilot hole cleaner, this product is especially useful when the insert position remains visible or when the buyer needs a more controlled installation result.

Material and Size Notes

The page mentions that threaded insert nuts can vary by size, application, and material. Metal options such as steel, zinc, and brass are often selected for strength and corrosion resistance, while plastic materials such as POM, ABS, or nylon may be used when a lighter or lower-cost solution is required.

For B2B orders, the final material and size should be confirmed according to the base material, screw size, required pull-out resistance, and cost target.

FAQ

Q1: What does Type D mean for this product?

This page refers to a headed hex-drive screw-in threaded insert with a sealing flange.

Q2: What is the purpose of the sealing flange?

The flange helps limit insertion depth and keeps the pilot hole opening tidier after installation.

Q3: Why is the self-tapping external thread important?

The self-tapping external thread helps the insert grip the material and improves resistance to torsion and vibration pull-out.

Q4: What size range is mentioned on the page?

The page mentions width from about 4mm to 16mm, thread diameter from about 2mm to 8mm, and insert length from about 6mm to 16mm.

Q5: What materials can be considered?

Common material directions include steel, zinc, brass, and plastic options such as POM, ABS, or nylon, depending on strength, corrosion resistance, weight, and cost requirements.
