FAQs

What size are these screws?

The screws are 6.3 x 125mm.

What is the head type?

The head type is an 8mm hex head.

What is the purpose of the EPDM washer?

The EPDM washer creates a watertight seal, preventing water from entering the structure.

What is the Elementech coating?

The Elementech coating is a corrosion-resistant coating that protects the screw from rust and extends its lifespan.

Do I need to pre-drill before using these screws?

No, the self-drilling T17 Gash Point eliminates the need for pre-drilling.

What is the maximum steel thickness these screws can handle?

These screws are suitable for a steel thickness of 0.5-1.2mm.

What materials are these screws compatible with?

These screws are designed for use with metal roofing panels and timber frames.

What is the salt spray test rating?

The screws have been salt spray tested to 1,000 hours.

Troubleshooting

Screw is not drilling into the timber.

Ensure you are using the correct size screw for the application. Make sure the drill is perpendicular to the surface and apply firm, even pressure. If the timber is particularly hard, consider pre-drilling a pilot hole.

The EPDM washer is damaged.

Check the alignment of the screw during installation. Over-tightening can damage the washer. Replace damaged screws.

Corrosion is visible on the screw.

Check the surrounding materials for any damage and replace the screw with a new one. Ensure the correct screw type has been used for the application.
