🛠️ Stop suffering from breakage caused by bi‑metal composite self‑drilling screws!

Bi‑metal screws are made by welding 435 and 304 materials together. The welding spot is the weak point, which brings hidden safety risks of weld separation.

Our one‑piece hex washer head self‑drilling screw features a 304 stainless steel cap covering the hex head. There is no welding process in the whole structure to eliminate weld separation risks.
Designed for outdoor long‑term use: the 304 stainless steel head effectively prevents rust and corrosion. It is much more cost‑effective than bi‑metal self‑drilling screws, making it an excellent alternative solution.

✅ No welding seam, completely avoid weld‑separation & breakage risks
✅ Lower cost than bi‑metal screws, ideal for roofing and steel structure projects
✅ Built‑in EPDM washer for reliable waterproof sealing
✅ Self‑drilling design, no pre‑drilling required for high installation efficiency

Full range of sizes available, custom orders are welcome. Message us for quotation.
