Good quality, fast shipping

The screws are sharp and the heads don't strip easily under high torque. The large flat head provides excellent clamping force. Just wish they came in smaller quantities for home users.

Great value for bulk buying

Bought these for a large warehouse project. They hold very well and the self-drilling tip works as advertised on 20-gauge steel. One star off because the box was slightly dented on arrival, but the screws were fine.

Perfect for metal framing jobs

These screws cut through steel studs like butter. The integrated washer saves a ton of time since I don't have to fumble with separate washers. The black finish looks professional too.

No pre-drilling needed

The drill tail design is legitimate. I skipped the pilot hole step entirely on my last job, which sped up installation by at least 30%. Highly recommend for HVAC work.

Strong hold and rust resistant

Used these for an outdoor shed frame. The rust-proof coating seems durable, and they haven't shown any signs of corrosion after a few weeks of rain. Very satisfied.

Best screws for the price

Factory direct pricing makes these unbeatable. Quality is consistent across the whole box. The cross drive fits snugly in my impact driver bits.

5 FAQ

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

A: These self-drilling screws are designed to penetrate up to 3mm (approximately 11-12 gauge) of mild steel without the need for a pre-drilled pilot hole.

Q: Do I need a special drill bit to use these?

A: No special bit is required. These screws feature a standard Phillips (PH2) head and can be driven using any standard power drill or impact driver with a PH2 bit.

Q: Is the washer removable or is it fixed to the screw?

A: The large flat washer is integrated and fixed to the screw head. It is designed to rotate freely during installation to prevent cam-out and ensure even pressure distribution.

Q: What is the tensile strength of these screws?

A: These high-carbon steel screws typically offer a tensile strength of approximately 600 MPa, making them suitable for structural framing and heavy-duty fastening applications.

Q: Are these suitable for outdoor applications?

A: Yes, the black oxide finish provides rust-resistant properties suitable for outdoor use, though we recommend additional sealing for areas with extreme moisture or salt exposure.
