These Unifix Drywall Screws (3.5 x 32mm, box of 200) are designed for DIYers and professionals working on internal plasterboard installations. The key benefit is their smooth countersinking and secure grip, ensuring a professional finish. A potential caveat is their suitability primarily for drywall and plasterboard, not harder materials. Features include a bugle head for flush finishing, a fine thread for excellent holding power, and a durable black phosphate coating for corrosion resistance.

These screws are designed for attaching drywall and plasterboard to wood or metal studs for internal wall and ceiling applications.
A bugle head is slightly rounded and tapered, allowing it to countersink smoothly into drywall without tearing the paper surface, creating a flush finish for easy plastering.
No, these screws have a black phosphate coating for improved corrosion resistance in internal applications only. They are not designed for outdoor or high-moisture environments.
The screws are made of steel for strength and reliability.
Each box contains 200 Unifix Drywall Screws.
No, these screws are specifically designed for use with plasterboard and suitable substrates like wood or metal studs. For brick or concrete, you would need appropriate anchors and different types of fixings.
The black phosphate coating provides enhanced durability and improved resistance to corrosion compared to uncoated screws, and it also helps paint adhere better to the screw head.
Ensure you are using the correct size and type of driver bit. Apply firm, consistent pressure directly in line with the screw. Avoid overdriving the screw into the drywall.
The drill speed may be too high, or too much pressure is being applied. Adjust the clutch setting on your drill/driver to a lower torque setting or slightly reduce the driving depth. Ensure the bugle head is properly seated.
Check that the screw is fully engaged in the stud (wood or metal). If fastening into wood, ensure the stud is solid and not rotten. For metal studs, ensure the screw has properly gripped the metal. The thread might be stripped in the stud material.
This can occur if the screws were exposed to excessive moisture during storage or installation. The black phosphate coating offers corrosion resistance but is not completely rust-proof, especially in damp conditions. Ensure the storage area is dry.
Setup:
These screws require a compatible power drill or drywall screw gun with an appropriate driver bit (typically Phillips #2). Ensure the driver bit is fully engaged with the screw head to prevent stripping.

Care:
Store screws in a dry environment to prevent premature corrosion of the coating. Keep the container closed to avoid contamination. Regularly check the condition of the screws before use, especially if stored for extended periods.
