Chipboard screws 6.0 x 140 partial thread - 100 pcs

Description

Strong 6.0 × 140 mm wood screws for heavy-duty wood-to-wood connections

These 6.0 × 140 mm partial thread chipboard screws are designed for strong wood connections where deep penetration and maximum clamping force are required. The screws are suitable for applications in solid wood, plywood, MDF, OSB and chipboard.

The Torx TX30 drive provides optimal grip and efficient power transfer during installation. This prevents cam-out and allows the screw to be driven in a controlled manner, even with longer screws like this 140 mm version.

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

Thanks to the combination of a 6.0 mm diameter and 140 mm length, this size is ideal for heavier wood connections where extra penetration depth and structural stability are required.

Why choose these chipboard screws?

✔ Ideal for 50–60 mm thick boards and beam connections
✔ Partial thread — strongly pulls two wooden parts together
✔ 6.0 mm diameter — high load capacity and stability
✔ Torx TX30 — excellent grip with reduced risk of slipping
✔ Suitable for heavy-duty wooden constructions
✔ Pack of 100 pieces — ideal for larger projects

When should you use 6.0 × 140 mm screws?

A 6.0 × 140 mm partial thread chipboard screw is used when an extra deep wood connection with maximum clamping force is required.

Common 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 140 mm a logical screw length?

For boards around 50 mm thick, a common guideline is:

The screw should penetrate 2.5 to 3 times the thickness of the top material into the lower wood piece.

50 mm × ±2.8 ≈ 140 mm

With a 140 mm screw, you achieve:

✔ Extra penetration depth in the supporting wood
✔ Very high pull-out resistance
✔ A stable structural connection

This makes 6.0 × 140 mm screws an excellent choice for heavier wooden constructions.

What makes these 6.0 × 140 screws suitable for MDF, plywood and solid wood?

When working with thicker wooden components, it is important that:

• The top material is pulled tightly into place
  
• The connection remains stable under load
• The screw provides sufficient grip in the supporting wood

Thanks to the partial thread, only the lower part of the screw grips into the wood. This actively pulls the upper material downward, creating a strong and stable connection.

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

Advantages of partial thread in 6.0 × 140 mm screws

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

This results in:

✔ Higher clamping force between two wooden parts
✔ Tighter connections between structural elements
✔ Less chance of visible gaps
✔ More efficient wood-to-wood fastening

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

Installation and mounting advice

For best results:

• Use a Torx TX30 bit
  
• Pre-drilling is usually not necessary in softwood
  
• In hardwood, a small pilot hole is recommended
• 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.
