Chipboard screws 6.0 x 90 partial thread galvanized - 100 pcs

Description

Strong 6.0 x 90 mm Wood Screws for Robust Wood-to-Wood Connections

These 6.0 × 90 mm partial thread chipboard screws are designed for strong wood connections where high clamping force and deep penetration are required. They are widely used in applications with solid wood, plywood, MDF, and chipboard.

The zinc-plated coating provides protection against corrosion and makes these screws suitable for indoor applications. Thanks to the Torx TX30 drive, torque is efficiently transferred during installation, preventing cam-out and allowing the screw to be driven in smoothly and with control.

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

With a 6.0 mm diameter and 90 mm length, this size is ideal for strong wood connections where additional penetration depth is required.

Why choose these chipboard screws?

✔ Ideal for 30–35 mm thick boards and panels
✔ 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
✔ Zinc plated — corrosion protection for indoor use
✔ Pack of 100 pieces — suitable for larger projects

When do you use 6.0 x 90 mm screws?

A 6.0 x 90 mm partial thread chipboard screw is used when a strong wood connection with extra penetration depth is required.

Typical applications include:

• Fixing 30–35 mm thick boards or panels
  
• Connecting wooden battens and beams
• Heavy furniture constructions
• Installation of thick plywood panels
• Wood-to-wood connections requiring high pull-out resistance

Why is 90 mm a logical length?

For a board thickness of approximately 30 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.

30 mm × 3 ≈ 90 mm

With a 90 mm screw, this ensures:

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

This makes 6.0 × 90 mm a widely used size for strong wood constructions.

What makes these 6.0 x 90 mm screws suitable for MDF, plywood and solid timber?

When working with thicker materials, 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 90 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 heavier wood connections, 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.
