A purlin screw is a specialized fastener designed for securing rigid insulation boards between timber purlins and timber trusses or rafters.

It features a T17 cutting point for easy installation into timber without the need for pre-drilling.

The screw provides a strong, stable hold, making it ideal for applications in roofing and insulation where durability and precision are required.

To install a purlin screw, use a S2 #5 Hex Bit with a power tool for efficient installation.

A 20V Impact Driver is ideal for this task, providing the necessary power for heavy-duty screw driving.

If using an Impact Drill or Hammer Drill, pre-drill a pilot hole to ensure proper insertion.

Avoid using a standard Drill Driver, as it may not provide adequate performance for installing purlin screws.

Purlin screws have versatile applications beyond their primary use, including:

1. Framing: Ideal for securing framing components in construction projects.
2. Fencing: Used to attach fencing materials to posts and supports.
3. Furniture Projects: Suitable for assembling various types of furniture where strong, reliable connections are needed.
4. Decking: Effective for securing decking boards to substructures.
5. Boxing: Useful in creating and reinforcing wooden boxes or crates.
