Product Description:

Collated drywall screws come in chain‑strip packaging for automatic feeding with strip‑fed screw guns. With black‑phosphate anti‑corrosion finish, countersunk Phillips head, sharp self‑drilling tip and coarse threads, these fasteners are specially‑made for fast installation of drywall sheets in light‑steel keel ceiling projects.

Key Features：

1. Collated chain‑strip design: Screws are mounted on plastic carrier strips for automatic screw‑gun feeding. It eliminates manual nail‑picking and greatly speeds‑up ceiling construction.
2. Black phosphate surface treatment: Good rust‑resistance and wear‑proof performance, low‑gloss finish for concealed indoor wall work.
3. Phillips countersunk head: Non‑slip cross drive, the flush‑sink head sits fully beneath the drywall for a smooth flat wall surface.
4. Sharp tip & coarse‑thread design: Sharp point pierces drywall effortlessly. Aggressive coarse threads offer powerful grip on metal keels to prevent wall‑board loosening.
5. Hardened carbon‑steel body: Quenched high‑strength steel resists bending and breakage during high‑speed driving.

Common Applications:

Ideal for light‑steel keel drywall ceilings, partition walls, indoor renovation, residential & commercial decoration, fiber‑board mounting, automated construction‑line fastening work.
