Core Advantages

1. Efficient Drywall Installation

The coarse thread provides strong thread engagement for Coarse Thread Drywall Screws, while the Phillips bugle head supports convenient screwdriver or power-tool installation. Available sizes range from 3.5 to 4.8 mm, covering common drywall fastening requirements.

2. Stable Bugle Head Design

The Drywall Screw uses a bugle head with a head diameter of 7.90–9.40 mm, helping distribute fastening pressure around the screw head and supporting a neat finish on drywall surfaces.

3. Reliable Mechanical Performance

These Coarse Thread Drywall Screws are manufactured from C1018–C1022 steel, with a surface hardness of a minimum of 550 HV and core hardness of 240–450 HV. The specified case depth reaches 0.05–0.23 mm, depending on the screw size.
