Collated Drywall Screws – Self Drilling Zinc – Trade

TIMco collated drywall screws are a straight-talking solution for anyone fixing plasterboard to steel stud or ceiling track. The self-drilling tip removes the need for a pilot hole, letting you drive straight into light-gauge steel track without losing your rhythm on the job. These are zinc-plated for basic corrosion resistance and come in strip-collated format, so they work directly with auto-feed screwdriver attachments from all the main power tool brands.

Available in four lengths — 3.5 x 35mm, 3.5 x 40mm, 3.5 x 45mm and 3.5 x 50mm — there is a size to cover most standard drywall-to-steel applications. Whether you are boarding out a stud partition wall or fixing boards to a suspended ceiling grid, these collated drywall screws are designed to keep pace with you rather than slow you down. Each box contains 1000 screws, which is a sensible quantity for anything beyond a small patch repair.

Where Collated Drywall Screws Make Sense

The main advantage of collated screws over loose screws is speed. On a full boarding job, fumbling for individual screws adds up to a lot of lost time across a day. With a collated strip and an auto-feed attachment, you are loading and driving in one motion, which makes a genuine difference on larger jobs. The strip format also reduces the chance of dropping screws or losing count of your spacing.

The self-drilling tip on these TIMco screws is rated for steel track up to 2.5mm thickness, which covers the vast majority of standard metal stud and track profiles used in drywall partition and ceiling systems. That point geometry means the screw starts cleanly without wandering, which matters when you are hitting a narrow track flange at pace.

Sizing and Thread Notes

The 3.5mm gauge is the standard diameter for drywall-to-steel work. The four available lengths let you match the screw to your board thickness and track depth. One thing worth noting: on TIMco self-drilling drywall screws, partial threading begins from 55mm upward. The sizes in this range — 35mm through to 50mm — are fully threaded, so they pull the board tight against the steel without the thread running out mid-fix. If you move up to 55mm or longer in the TIMco range, the threading changes, so it is worth being aware of that if you are mixing sizes on site.

These collated drywall screws are a practical everyday trade item. A 1000-box gets a boarding crew through a decent stretch of work without constantly reordering, and the consistent strip format means fewer jams in the auto-feed tool. At 3.5mm gauge, they hit the sweet spot for standard partition and ceiling work without overdriving into thinner board profiles.
