Hardened wood screw 4.0x40mm countersunk head TX drive yellow zinc plated /250pcs/ TS-4040

Hardened structural screw for wood and chipboard

The TS-4040 hardened structural screw with a diameter of 4mm and a length of 40mm is a specialized fastening element designed for the professional assembly of various wood species and chipboards. Made of electro-galvanized low-carbon steel, it ensures long-lasting corrosion resistance, while the hardened structure guarantees exceptional mechanical strength during operation.

Ribbed thread with a lubricating wax layer

The screw is equipped with a special ribbed thread coated with a lubricating wax layer, which significantly reduces the force required for insertion and minimizes the torque required from the tool. The partial thread allows for secure clamping of the fastened elements, ensuring a stable connection without the risk of loosening. Milling ribs located under the countersunk head guarantee easy and smooth embedding of the element into the material without the need for additional surface preparation.

Torx drive system and assembly quality control

The TX20 (Torx) drive ensures optimal torque transfer and effectively protects against uncontrolled bit cam-out during work. The Torx socket eliminates the problem of head "stripping" and allows for precise control of the tightening force. The countersunk head shape allows for full flush mounting with the surface of the fastened element, resulting in an aesthetic appearance of the connection.

Protection against material damage

A drilling flute located at the tip of the screw effectively prevents the cracking of delicate wood-based materials during assembly. The special blade geometry eliminates the need for pre-drilling pilot holes in most standard applications. The design reduces the risk of splitting MDF or OSB boards at edges and corners.

Applications in fastening various materials

The screw finds wide application in fastening plywood, chipboard, OSB materials, and various species of solid wood. It is used in the construction of structures requiring durable structural connections. The system enables working with elements of different thicknesses without the need to select specialized solutions for each type of material.

The screws are hardened to increase mechanical strength and coated with yellow zinc for corrosion protection.
