Drywall Screw For Ceiling Global Supplier
Drywall Screws for Ceiling are professional fasteners designed for screwing drywall to ceiling. They are made of high-strength low-carbon steel, which is both rust-resistant and high-load-bearing. Their self-tapping pointed head and deep thread design can quickly penetrate the gypsum board and firmly bite the light steel keel or wooden frame. They are suitable for ceiling installation in residential and commercial spaces. They solve the pain points of screws being easy to loosen and rust, and solve the problem of ceiling screws popping.
Core Features Of Plasterboard ceiling screws
Super strong load-bearing, safe and anti-falling
High hardness material (HRC 52-55): single vertical tension ≥180kg (#8×38mm), load-bearing performance is 60% higher than ordinary screws.
Double thread locking technology: main thread quickly taps in, secondary thread reversely locks, vibration resistance is improved by 70%.
Galvanized anti-rust, durable
Galvanized layer (≥4μm): passed ASTM B117 salt spray test, corrosion resistance life of up to 10 years, suitable for high humidity environments such as bathrooms and kitchens.
Optional black phosphating coating: hidden and beautiful, suitable for open ceiling design.
Self-tapping tip, efficient installation
No need to pre-drill, directly penetrate the gypsum board and light steel keel (≤1.2mm thickness), saving 30% of working hours.
Applicable tools: electric screwdriver (PH2 bit), speed ≤3000 RPM.
Universal design, flexible adaptation
Frame compatible: light steel keel (No. 25), wooden frame, metal hanger.
Head optimization: countersunk head design is embedded in the board surface to prevent cracking.

Applicable Scenarios Of Drywall Screws For Ceiling
Commercial building ceiling
Fix gypsum board to Metal Framing for Ceiling, suitable for office and shopping mall ceilings (search term:).
Recommended specifications: 4.2mm×38mm galvanized type, screw spacing ≤30cm.
Indoor fire partition
Matched with fireproof gypsum board, used for hotel and hospital partitions, it is the best Fire-Rated Drywall Screws
Recommended specifications: 4.2mm×50mm Dacromet coated type, in line with UL fireproof certification.
Outdoor semi-open structure
Fix metal frame of canopy and advertising board
Recommended specifications: 4.8mm×50mm Dacromet + sealant coating type.
Diameter (key to tensile strength)
3.5mm (#6)
Application: light ceiling (residential, small space), gypsum board thickness ≤12.5mm.
Tensile value: ≥120kg/piece (ASTM standard).
4.2mm (#8)
Application: commercial ceiling, composite structure or high humidity environment (bathroom, kitchen).
Tensile value: ≥180kg/piece, shear strength increased by 40%.
Single-layer gypsum board (9.5-12.5mm) + thin metal keel (0.5-0.8mm), 25mm (1 inch) sheetrock screws are recommended to avoid excessive penetration, which is the best drywall screws for ceiling
Single-layer gypsum board + standard light steel keel (0.6-1.0mm), or double-layer gypsum board edge reinforcement.
32mm (1-1/4 inch) drywall screws are recommended, which are versatile and balance penetration and safety.
Double-layer gypsum board (total thickness ≥25mm) or composite ceiling with sound insulation cotton
38mm (1-1/2 inch) sheetrock screws are recommended for deep fixing to prevent the board from sagging.
Heavy metal keel (≥1.2mm) or wooden keel ceiling (higher pull-out resistance is required).
50mm (2 inch) sheetrock screws are recommended, which have ultra-high load-bearing capacity and are suitable for commercial spaces (such as shopping malls and office buildings).
Plasterboard Ceiling Screws Installation Guide
Screw spacing
Light steel keel: ≤15cm at the edge, ≤30cm in the middle, and the intersection must be hit.
Wooden keel: ≤20cm evenly distributed, avoiding wood knots and cracks.
Tool selection
Metal keel: electric screwdriver (PH2 bit, speed ≤2500 RPM).
Wooden keel: impact drill (hexagonal head, pre-drilled holes to prevent cracking).
Depth control
The countersunk head is embedded in the plasterboard ≤1mm to ensure that the putty covers evenly.
Over-tightening will cause the board to break, and it is recommended to use an electric tool with a clutch function.
Installation Guide (solving user pain points)
Tools and settings
Tool selection: It is recommended to use an electric screwdriver (speed 2000-2500 RPM) with a magnetic bit to prevent falling.
Torque control: Set to 3-4Nm to avoid over-tightening and causing plasterboard to break.
Installation Specifications
Screw spacing: ≤15cm for the edge, ≤30cm for the middle area, screws must be screwed at the intersection of the keel.
Depth standard: The countersunk head should be embedded in the board surface ≤1mm, ensuring that the surface is flat after the putty is covered.
FAQ
FAQ
ask us
anything
What should I do if the ceiling screws rust and cause the gypsum board to turn yellow?
*Immediately replace with stainless steel or Dacromet coated screws, and apply anti-rust paint + putty on the rusted areas
Can fine thread screws be used for wooden keels?
*Not recommended! Coarse threads have a stronger grip in wood, and fine threads are easy to loosen.
There is a gap between the gypsum board and the keel. How to adjust the screw length?
*Formula: Screw length = gypsum board thickness + gap width + embedded in the keel at least 12mm.
Do ceiling screws need to be pre-drilled?
No! The self-tapping tip can directly penetrate the gypsum board and light steel keel, but it is recommended to pre-drill small holes for super thick metal (>1.5mm)
Will galvanized screws leave rust?
The hot-dip galvanized layer is extremely rust-resistant and will not rust under normal use. If the coating is damaged, it can be partially repainted.
How long should the screws be for wooden frame ceilings?
Formula: Screw length = gypsum board thickness + at least 20mm embedded in the wood frame (e.g. 32mm screws for 12mm boards）
Can it be used to connect gypsum boards to concrete ceilings?
No! You need to install wooden keels or metal hangers first, then fix the gypsum boards.
Why do drywall screws pop out on ceilings?
Wood keels shrink due to humidity changes, causing screws to loosen.
