Collated Drywall Screws Coarse Thread

Collated drywall coarse thread screws are designed for fixing plasterboard to timber frames. They come joined in strips, so an autofeed screw gun can drive them one after another, speeding up installation.

What Are Collated Coarse Thread Drywall Screws?

They are manufactured from carbon steel, usually finished with black phosphate coating for smoother driving, and linked together on a plastic or paper strip.

The screws are collated on paper or plastic strips that load directly into a collated screw gun. The screw gun’s adjustable nosepiece controls depth and, with depth consistency, ensuring uniform fixing across the plasterboard.

The spiral ridges on coarse thread screws are deep and wide. This shape allows the screw to bite into timber fibres to provide strong, pull-out resistance. Course threads are ideal for timber, not metal.

The bugle head seats neatly into the board and distributes pressure as the screw tightens, keeping the plasterboard flat without ripping the paper face.

They are available in different sizes, including 50mm, 35mm and 32mm coarse thread collated drywall screws. It is easy to match screw length to board thickness and frame depth.

What Are Drywall Collated Coarse Drywall Screws Used For?

Collated coarse thread drywall screws fix plasterboard to timber studs or joists.

They are chosen because:

• Coarse threads lock into wood without stripping
• Collated strips speed up repetitive fixing
• Screws drive to a consistent depth
• Boards stay tight to the frame over time

Drywall coarse thread joined screws are common on large timber-framed walls and ceilings. On thin steel frames, these screws would chew the metal instead of gripping it, which is why metal studs use fine threads instead.

What lengths of drywall collated coarse screws do I use?

Choose a screw length long enough to go through the plasterboard and into the timber without breaking through the rear of the stud or joist.

• 32mm coarse thread collated drywall screws – Single board to timber walls.
• 35mm coarse thread collated drywall screws – Common for ceilings where extra holding depth is needed due to gravity.
• 50mm coarse thread collated drywall screws – Thicker boards or double-layer plasterboard.

Longer screws give more grip in wood, but only if the timber depth can accommodate them. The goal is a firm hold, not excess penetration.
