Zipco Zinc Gypsum (POP) Screws are 3.5 mm diameter screws, available in lengths from 19 mm to 50 mm, made for fixing gypsum boards, drywall and light wooden work. Their sharp threads bite in easily and hold firmly, without cracking the board.

Made from hardened carbon steel with a smooth, shiny metallic Zinc plating, they resist rust in indoor conditions and give a clean, bright finish. Use them for false ceilings, drywall partitions and wooden framing on home and commercial interior projects. Supplied in boxes of 200 to 1000 screws depending on length, for tidy storage on site.

Recommendations & Ideal Use-Cases

How to Use

1) How are gypsum screws different from regular screws?

Gypsum screws have sharp, fine threads designed for gypsum boards. They grip soft board material firmly without cracking or crumbling it, which regular wood screws can do.

2) Can I use these for drywall installation?

Yes. The 3.5 mm size and sharp threads make them ideal for fixing gypsum boards to metal or wooden studs in partition walls and ceilings.

3) Which driver bit should I use?

Use a Phillips #2 (PH2) bit. Pre-drilling is not usually needed in gypsum board. In hardwood, or near the edge of thin wood, drill a 2.5 – 3 mm pilot hole to avoid splitting.

4) How many screws do I need per gypsum board?

Typically, space screws 200 – 300 mm apart along the edges and 300 – 400 mm apart across the middle of the board. A standard 8 x 4 ft board usually needs about 40 – 50 screws, depending on the frame layout.

5) Can I use them for wooden work?

Yes, for light wooden work such as thin panels, trim and light framing. For heavy-duty structural woodwork, use dedicated wood screws.

6) How deep should the screw head go?

The head should sit slightly below the surface. This lets you cover it smoothly with joint compound in drywall work, without leaving bumps. Avoid driving so deep that the board's paper face tears.

7) Are these screws rust-resistant?

Yes, for indoor use. The core is hardened carbon steel, finished with a smooth, shiny metallic Zinc plating instead of a porous black phosphate coating. The zinc layer protects the steel against rust and corrosion in interior drywall, false ceiling and woodworking applications.

8) Which length should I buy?

Pick a length that passes through the board and goes at least 10 mm into the frame behind it. For a single 12.5 mm gypsum board, 25 mm screws are the usual choice. For double layers or thicker boards, use 32 – 38 mm. Use 19 mm for thin panels and trim, and 50 mm for light wooden framing.
