Applications

oCoarse Thread Drywall Screws :Coarse-thread drywall screws work best for most applications involving drywall and wood studs. But the wide threads are good at gripping into the wood and pulling the drywall against the studs.
oFine Thread Drywall Screws:Fine-thread drywall screws are best for installing drywall to metal studs. But coarse threads have a tendency to chew through the metal, never gaining proper traction. Fine threads work well with metal because they are self-threading.

We have more than 20 years experiences on fasteners. We are a typical  China factory.
We are professionally exporting under the standards of DIN, JIS, GB, ANSI, and BS, as well as nonstandard fasteners. Now we have gained close cooperation with clients from Russia, Iran, Europe, and America, and won good comments from users.
