DIN 1624 Furniture Knock-in Nut (Insert Type)
FLOK supplies DIN 1624 furniture knock-in nuts: C1008 steel property class 8/10, A2/A4, zinc, M4–M10. For furniture assembly and fastening in wood.
DIN 1624 is a furniture knock-in nut designed for joining various elements made of wood and wood-based materials.
Structurally, the fastener consists of two parts: a flange with 4 pointed prongs for secure fixation in the material, and a cylindrical sleeve with an internal thread of various diameters. This type of fastener is used together with bolts, screws or studs when joining parts in furniture manufacturing. The nut provides a secure attachment of the product and prevents it from rotating in the material.
Materials
The primary material used to manufacture this type of fastener is C1008 carbon steel, property class 8 or 10. This provides the ability to withstand significant loads during furniture assembly and use. To extend service life and improve corrosion resistance, the products are supplied with a zinc coating. The galvanized metal takes on an attractive sheen, and the coating enhances the product’s protective and decorative properties.
The product can also be manufactured from A2 and A4 stainless steel. These alloys contain austenitic additives that provide strength and resistance to aggressive environmental effects. Stainless steel fasteners do not deteriorate on contact with moisture or atmospheric air.
Technical specifications
The fastener is manufactured according to the following dimensional characteristics:
- The metric thread diameter of the bore ranges from M4 to M10.
- The thread pitch can range from 0.7 to 1.5 mm.
- The outer diameter of the sleeve can be from 5.2 to 12.3 mm.
- The diameter of the flange base is from 15 to 25.4 mm.
The fastener with the flange base is installed into a pre-drilled hole, with the prongs embedding into the wood. They prevent spontaneous loosening even under frequent dynamic loads.
Application options
The main application of this type of fastener is furniture manufacturing, but it is also used more broadly. In furniture assembly, it is used to join parts together with bolts, screws and studs of the corresponding thread diameter. Knock-in nuts have a design that allows installation even in confined spaces.
They are used in installation and finishing work with soft materials. This type of fastening improves the reliability of the joint between parts. Furniture nuts of this type make it possible to avoid self-tapping screws and nails, and the joint created with them is stronger.

DIN 1624 Furniture Knock-in Nut (Lug Type)
Used in construction and wood installation work. Suitable for fastening in furniture and similar frames using bolts, screws and other metric connections. Drilling is required before installation. The points on the cap bite into the surface and prevent the nut from rotating, providing additional fixation. The DIN 1624 furniture knock-in nut (lug type) is made of electro-galvanized carbon steel.
