BP Coarse Thread Drywall Screws
BP Coarse Thread Drywall Screws have a wider thread pitch, meaning the threads are farther apart. This makes them better for gripping into softer materials like drywall, and they are typically used for attaching drywall to wood studs.
Black phosphate drywall screws are used for a variety of reasons, including:
- Aesthetics: The black colour of the screws can blend in better with the surrounding surface, making them less noticeable.
- Grip: The black phosphate coating provides a better grip than zinc coating, which can make it easier to drive the screws into the drywall.
- Cost: Black phosphate coating is generally less expensive than zinc coating, making it a more cost-effective option.
- Resistance: Black phosphate coating provides a moderate level of resistance to corrosion, which is suitable for indoor use.
- Compatibility: Black phosphate coating is compatible with a variety of materials and substrates, making it a versatile option.
