Why Your Self-Drilling Screws Won’t Bite — And How to Fix It

You press the drill. The screw spins. The metal won’t give. Then the tip dulls, or the head snaps off.

It’s frustrating—but the screw isn’t always the problem.

At XIAOJUN FASTENER, we supply C1022A carbon steel self-drilling screws to importers and contractors worldwide. We see four common causes:

1. Too much speed. High RPM burns the drill point. Use low speed and steady pressure.

2. No starting point. On smooth steel or roofing sheets, the tip slides. Use a punch mark or start slowly to let the point bite.

3. Wrong torque. Low torque spins without cutting. Choose low speed, high torque.

4. Wrong screw for the job. C1022A carbon steel screws are designed for steel, wood, and plastic—not for stainless steel or other high-hardness materials. Point angle, thread pitch, and heat treatment all matter.

At XIAOJUN FASTENER, we manufacture C1022A carbon steel self-drilling screws with precise point geometry and consistent heat treatment. They start faster, drive cleaner, and reduce breakage in standard steel and roofing applications.

We support OEM/ODM, custom coatings, sizes, and packaging. Export-ready quality. Competitive factory pricing. Fast samples.

Don’t let a bad screw slow down your project—or your business.
