FAQs

What materials are these screws best for?

These screws are best for plasterboard and general wood applications.

Do I need to pre-drill?

Yes, it is highly recommended to pre-drill pilot holes before inserting the screws.

What size drill bit should I use?

Use a drill bit slightly smaller than the screw's diameter.

Are these screws rust-resistant?

Yes, the zinc plating provides corrosion resistance.

What is the length of the screws?

The screws are 70mm in length.

Can I use these screws outdoors?

While the zinc plating offers some protection, consider using screws specifically designed for outdoor use for prolonged exposure to the elements.

What type of head do these screws have?

They have a double-countersunk head.

Troubleshooting

Screw head strips while driving.

Use the correct screwdriver bit size and apply even pressure. If the hole is stripped, try a slightly larger screw or fill the hole with wood filler.

Screw won't go in straight.

Ensure the pilot hole is straight and centered. Apply even pressure while driving the screw.

Screw is difficult to drive in.

Pre-drill a larger pilot hole, especially when working with hardwoods. Use a lubricant like wax or soap on the screw threads.

Pros and Cons

Pros

Setup, Compatibility & Care

Setup:

  1. Pre-Drilling: Always pre-drill a pilot hole slightly smaller than the screw's diameter to prevent wood splitting and ensure easy insertion.
  2. Insertion: Use a screwdriver or drill with the correct bit size for the screw head to drive the screw in straight.
  3. Tightening: Avoid over-tightening, as this can damage the material and strip the screw hole.

Compatibility:

  • Suitable for use with various hand tools and power tools.

Care:

  • Store screws in a dry place to prevent corrosion.
