Its standout feature is the continuous special thread that enables stress-free, durable installation by preventing the frame from being pulled against the substrate.

FAQs

Do I need a special drill bit for these screws?

Yes, you must use a T30 Torx driver bit for this specific screw head.

Is pre-drilling required for all materials?

Yes, the FFS screw requires a pre-drilled hole in solid and perforated building materials to function correctly.

Can these screws be used outdoors?

The screws are designed for standard installations, but ensure they are properly sealed if exposed to direct, heavy weather to prevent potential corrosion.

Are these screws removable?

Yes, they can be backed out using a T30 bit, though care should be taken not to damage the substrate during removal.

How many screws come in a box?

Each pack contains 100 pieces.

Troubleshooting

Screw is difficult to drive into the material

Check that the pilot hole diameter is appropriate for the material type and that the drill bit is not worn down.

Head stripping during installation

Ensure the T30 bit is fully seated in the head and apply firm, constant axial pressure while driving.

Frame is not holding securely

Verify that the material substrate has not crumbled due to over-drilling and ensure the screw has reached the required depth.

Pros and Cons

Pros

  • Stress-free installation prevents frame deformation
  • High-quality steel construction for durability
  • Compatible with a diverse range of substrate materials
  • Efficient Torx T30 drive for stable power transfer
  • Cost-effective for high-volume frame installations

Cons

  • Requires professional-grade drilling before insertion
  • Limited to specific 132mm depth requirements
  • Not suitable for materials softer than wood or thin-wall hollow sections without proper anchoring

Setup, Compatibility & Care

For optimal results, ensure the correct drill bit size is selected based on the specific masonry substrate to ensure the thread grips effectively. Always verify that the frame is level and shimmed appropriately before driving the screws, as the thread prevents manual adjustment once fully seated. Keep the screws in a dry environment to maintain the integrity of the silver coating, which provides basic corrosion resistance. When installing, use a high-torque electric or cordless drill with a dedicated T30 bit to avoid stripping the screw head.
