Product Information

Full details

The TIMco Window Fabrication Screws (4.2 x 16mm) are designed for professional window installers and fabricators who need a reliable, high-strength solution for attaching steel hardware to steel-reinforced PVCu sections. These screws offer the primary benefit of self-tapping and self-drilling efficiency in metal substrates, ensuring a secure and firm hold with their pan head design. The main caveat is that these screws are specifically optimized for a maximum drilling thickness of 3.0mm, making them unsuitable for heavy-duty structural steel applications beyond this limit.

FAQs

Can I use these screws in coastal areas?

These screws are suitable for low salt atmosphere environments but are not recommended for direct, high-salt marine environments.

What size driver bit do I need?

These screws require a standard Phillips PH2 driver bit.

Are these screws self-tapping?

Yes, they feature a self-tapping and self-drilling design for efficient installation into steel.

What is the maximum steel thickness they can handle?

They are rated for a maximum drilling thickness of 3.0mm.

Do I need to pre-drill holes?

No, the self-drilling point removes the need for pre-drilling when used on compatible steel substrates.

Do these meet building regulations?

Yes, they are tested to BS EN ISO 9227:2006 and comply with BPF and GGF guidelines for window fabrication.

Troubleshooting

Screw tip is skidding off the metal surface

Ensure you are applying firm, steady pressure before engaging the drill and verify the angle is perfectly perpendicular to the substrate.

Head stripping during installation

Check that the PH2 bit is not worn down; if it is, replace the bit to ensure a snug fit in the screw recess.

Screw is failing to penetrate the steel

Verify that the material thickness does not exceed the 3.0mm limit, as this screw is not designed for thicker steel.

Pros and Cons

Pros

  • Excellent resistance to corrosion in urban settings
  • Fast installation due to self-drilling capability
  • Secure, flush fastening thanks to pan head design
  • Meets strict BPF and GGF industry guidelines

Cons

  • Limited to a maximum steel thickness of 3.0mm
  • Requires specific PH2 driver bits for best results
  • Not intended for high-salt marine environments

Setup, Compatibility & Care

To achieve the best results, ensure your power driver is set to the correct torque to prevent over-tightening or stripping the thread.

  • Compatibility: These screws are exclusively designed for steel reinforcement within PVCu. Do not use on materials exceeding 3.0mm in thickness.
  • Tooling: Use a high-quality PH2 drive bit to prevent cam-out and ensure a tight finish.
  • Storage: Store in a cool, dry place to maintain the integrity of the silver organic finish.
  • Installation Tip: Always start the screw perpendicular to the surface to ensure the drill point initiates correctly without skidding.
