Chipboard screws 6.0 x 120 partial thread - 100 pcs

Description

Strong 6.0 x 120 mm Wood Screws for Heavy-Duty Wood-to-Wood Connections

These 6.0 × 120 mm partial thread chipboard screws are designed for strong wood connections where deep penetration and high clamping force are required. The screws are suitable for applications in solid timber, plywood, MDF, OSB and chipboard.

The Torx TX30 drive provides optimal grip and efficient torque transfer during installation. This prevents cam-out and allows the screw to be driven in smoothly and with full control — even with longer screws such as this 120 mm version.

The countersunk head sits neatly flush with the wood surface, providing a clean finish for both structural work and visible applications.

With a 6.0 mm diameter and 120 mm length, this screw size is ideal for heavy wood connections where maximum stability and penetration depth are required.

Why choose these chipboard screws?

✔ Ideal for 40–50 mm thick boards and beam connections
✔ Partial thread — firmly pulls two wooden parts together
✔ 6.0 mm diameter — high load capacity and stability
✔ Torx TX30 — optimal grip with reduced risk of cam-out
✔ Suitable for heavy wood constructions
✔ Pack of 100 pieces — ideal for larger projects

When do you use 6.0 x 120 mm screws?

A 6.0 × 120 mm partial thread chipboard screw is used when a deep wood connection with maximum clamping force is required.

Typical applications include:

• Fixing 40–50 mm thick boards
  
• Connecting wooden beams and battens
• Heavy furniture constructions
• Timber frame constructions and structural framing
• Wood-to-wood connections requiring high pull-out resistance

Why is 120 mm a logical length?

For a board thickness of approximately 40 mm, the general guideline is:

The screw should penetrate at least 2.5 to 3 times the thickness of the top material into the supporting timber.

40 mm × 3 ≈ 120 mm

Using a 120 mm screw ensures:

✔ Sufficient penetration depth
✔ High pull-out resistance
✔ A very stable structural connection

This makes 6.0 × 120 mm an excellent choice for heavy timber constructions.

What makes these 6.0 x 120 mm screws suitable for MDF, plywood and solid timber?

When working with thick wood components, it is important that:

• The top material is firmly pulled against the supporting timber
• The connection remains stable under load
• The screw has sufficient grip in the supporting wood

Thanks to the partial thread, only the lower section of the screw engages the timber. This actively pulls the upper material downward, creating a strong and stable connection.

The 6.0 mm diameter also provides additional torsional and bending strength during installation.

Advantages of partial thread at 6.0 x 120 mm

Unlike full thread screws, this version has thread only on the lower section.

This results in:

✔ Higher clamping force between two wooden parts
✔ Tighter connection of structural components
✔ Reduced risk of open joints
✔ More efficient wood-to-wood fastening

For structural wood connections with thick boards or beams, partial thread screws are often the preferred choice.

Installation and mounting advice

For best results:

• Use a Torx TX30 bit
  
• Pre-drilling is usually not required in softwood
• A small pilot hole is recommended in hardwood
• Drive the screw slowly and in a controlled manner

Tip: see our category for screwdriver bits and holders to select the correct bit size and quality.
