Chipboard screws 4.5 x 60 partial thread

Description

Reliable 4.5x60 mm wood screws for strong wood-to-wood connections

These 4.5 × 60 mm chipboard screws with partial thread are designed for medium-duty wood-to-wood connections in MDF, OSB, chipboard, plywood and solid timber. The zinc-plated coating provides corrosion protection for indoor use.

The Torx TX20 drive ensures optimal bit grip, reduces cam-out and allows controlled installation. The countersunk head sits flush in the material, making these screws ideal for visible interior applications.

With a 4.5 mm diameter and 60 mm length, this size is especially suitable for fastening boards of approximately 20–24 mm thickness to timber frames or battens.

Why choose these chipboard screws?

✔ Ideal for 20–24 mm thick boards
✔ Partial thread — pulls two timber parts tightly together
✔ 4.5 mm diameter — increased strength compared to 4.0 mm
✔ Torx TX20 — prevents cam-out and head damage
✔ Zinc plated — corrosion protected for indoor use
✔ Pack of 200 pieces — suitable for medium-sized projects

When do you use 4.5 x 60 mm screws?

A 4.5x60 mm partial thread chipboard screw is commonly used when sufficient penetration depth is required without excessive protrusion.

Typical applications include:

• Fixing 20–24 mm thick boards to timber framing
• Cabinet and furniture construction
• Interior timber framing and battens
• Wall cladding and interior finishing
• General wood-to-wood structural fastening

Why is 60 mm a logical length?

When fastening 20–24 mm boards, the general rule is:

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

20 mm × 2.5 = 50 mm
24 mm × 2.5 = 60 mm

This ensures:

✔ Sufficient holding power
✔ Strong pull-out resistance
✔ Structural stability
✔ Reduced risk of joint movement

This makes 4.5x60 mm a popular size for medium-duty timber constructions.

What makes 4.5x60 mm suitable for MDF, OSB and solid timber?

When working with thicker materials, it is essential that:

• The top material is pulled tightly against the substrate
• The joint remains stable under load
• The screw provides adequate penetration depth

The partial thread design grips only in the lower timber section. This actively pulls the upper board down, creating a tight and secure joint without leaving gaps.

The 4.5 mm diameter adds torsional strength and improved resistance to bending during installation.

Advantages of partial thread at 4.5x60 mm

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

This results in:

✔ Higher clamping force between two timber parts
✔ Better tightening effect in framing applications
✔ Reduced risk of gaps between materials
✔ More efficient wood-to-wood fastening

For fastening boards onto timber framing, partial thread is often the preferred choice.

Installation and mounting advice

For optimal results:

• Use a Torx TX20 bit
• Pre-drilling is usually not required in softwood
• Pre-drilling is recommended in hardwood
• Drive screws steadily to avoid material damage
