Perfect for metal framing

These screws drill through sheet metal effortlessly. The black finish looks professional and the rust protection seems solid so far.

Good value for bulk purchase

Bought a large box for a warehouse project. Most of them worked perfectly, though I found one or two with slightly stripped heads. Overall great price.

Sharp drill points

The drill tail feature is very sharp and cuts cleanly without needing a pilot hole. Saved us hours on the job site.

Solid industrial screw

Exactly as described. The black coating is even and provides good coverage. Would recommend for indoor or covered outdoor use.

Holds tight

Used these to attach brackets to steel beams. They hold extremely well and the cross recess allowed for good torque application.

5 FAQ

Q: Is the black coating suitable for outdoor exposure?

A: The black zinc plating offers basic rust protection suitable for indoor use or sheltered outdoor areas. For harsh marine environments, we recommend stainless steel alternatives.

Q: What size Phillips bit is required for these screws?

A: Depending on the specific diameter of the screw you selected, you will typically need a PH2 or PH3 Phillips driver bit.

Q: Are these screws compatible with aluminum sheets?

A: Yes, they work well with aluminum. However, due to the hardness difference, ensure you do not overtighten to avoid stripping the threads in the softer aluminum.

Q: Do these come in different lengths?

A: This specific listing is for the standard length variety. Please check our other listings or contact us directly for custom length requirements.

Q: What thickness of metal can these screws penetrate without a pilot hole?

A: These self-drilling screws are designed to penetrate mild steel up to 3mm thick without the need for a pre-drilled pilot hole.
