Bugles Screws
The head has a unique trumpet-shaped design.When screwing in, this shape can smoothly guide the screw head to sink under the surface of the material (such as gypsum board), effectively avoiding tearing or bulging of the material surface.

Bugle Head Screw Series
Sinsun’s Bugle Head Screws are a type of screw designed specifically for drywall installation. The name comes from its unique “flared” head design, which is gently curved and gradually thins to the edge. This design allows the screw to sink smoothly into the drywall surface, avoiding tearing the paper surface of the gypsum board, while providing a flat base for subsequent caulking and sanding. These features make it the best wall screws for fixing sheetrock to wooden or metal frames. At the same time, our Bugle Screw can also be used for 5/8 drywall.
Bugle Head Self Drilling Screw

Outdoor gypsum boards (waterproof treatment required) are fixed on antiseptic wood or steel structures.
75mm Bugle Screws
Our 75mm Bugle Drywall Screws are mainly used to fix gypsum board to metal frame on concrete/brick wall (need to use nylon anchor bolts).
Install external wall insulation layer + gypsum board composite system (penetrate the insulation wool and fix to the structural layer).
50mm Bugle Screws
insun’s 50mm Bugle Drywall Screws are designed for fixing double-layer gypsum board (such as 12.5mm + 12.5mm sound insulation / fire protection combination) to single-layer gypsum board installed on thick wooden frame or heavy metal keel (≥18 gauge).

Bugle Screw Common Specifications
In daily decoration, the size of Bugle Screw is generally selected with a screw diameter of #6, which is 3.5MM, for general use, and #8, which is 4.2MM, for heavy-duty construction, such as installation of double-layer gypsum board or fireproof board. At the same time, sinsun provides customization of any size to meet the different requirements of your project.
1-1/4 Sheetrock Screws
1-1/4″ Sheetrock Screws are screws designed for fixing standard 1/2-inch thick gypsum board (Sheetrock/drywall), suitable for home decoration, commercial engineering and other scenarios. Sheetrock is the gypsum board brand of USG Corporation in the United States, but “Sheetrock Screws” has become a common term in the industry, synonymous with “drywall screws”
1-5/8 Drywall Screws
Sinsun’s 1-5/8″ Drywall Screws are extended screws designed for thick gypsum board or ceiling projects. They are 3/8 inches longer than standard 1-1/4″ screws and are suitable for higher-strength installation needs. They are also called “ceilings screws” or “heavy-duty drywall screws”.
25mm Plasterboard Screws
Our 25mm Plasterboard Screws are universal screws designed for fixing standard 12.5mm thick plasterboard (about 1/2 inch) and are suitable for home decoration, commercial partition and ceiling projects. Its length and design balance penetration and stability, and it is a common choice in the European, Australian and Asian markets.
Bugle Screw Thread Type
Thread is a very important factor of Bugle Screw. Improper use will cause great trouble. Misuse of fine thread on wooden frame will lead to insufficient grip, and misuse of coarse thread on metal frame will cause thread slippage.
Coarse Thread
Coarse thread design enhances the grip on wood and prevents loosening, that is the best screw for wood, suitable for wooden frames (such as pine and fir).
Fine Thread
Fine Thread is specially designed for metal frames to prevent thread slippage. It is the best screw for metal studs and can penetrate light steel keels (25-20 gauge) without pre-drilling.
The Core Purpose Of The Bugle Screw
- Fastening 1/2″ or 5/8″ drywall to wood studs:
Coarse threads provide a secure grip on wood and prevent drywall from loosening. - Metal framing installation:
Fine-threaded Bugle Screws penetrate light steel studs (25-20 gauge) without pre-drilling. - Repairing loose wallboard:
Replace aged nails or loose screws to restore wall surface flatness. - Ceiling drywall installation:
Use extended-length (e.g., 1-5/8″) screws to ensure drywall fits snugly against ceiling studs. - Multiple layers of drywall stacking:
When fastening double layers of soundproof or fire-resistant drywall, short Bugle Screws (1″) avoid penetrating the bottom layer.
Phillips Bugle Head
The bugle head sinks smoothly into the gypsum board, reducing damage to the paper surface and reducing the cost of later repairs

Bugle Head Screw Installation Tips
Spacing Specification
Install one screw every 12-16 inches along the wooden keel, leaving 3/8 inches on the edge to prevent cracking.Ceilings can be denser to 8-12 inches.
Avoid Overtightening
Use a drywall screw gun with depth adjustment to ensure that the screw head is slightly sunk into the board surface 1/32–1/16 inches (about 0.8–1.5mm). Screws sunk too deep will weaken the fixing force..
Installation Tools
For efficient installation, you can use a drywall screw gun,Sinsun’s screws can be matched with most tools on the market. DEWALT DCF620B with depth adjustment is recommended to prevent over-tightening
Magnetic Bit
Ordinary electric drill + depth adjustment socket with magnetic screwdriver bit.
The automatic stop function ensures that the screw head sinks 1/32-1/16 inch into the board surface, preventing the screw from falling off frequently
FAQ
What is the difference between Bugle Screw and other screws？
Head design: Bugle Head avoids tearing the surface of the gypsum board, while the sharp head of ordinary screws can easily damage the paper surface.
Can the Bugle Screw be reused?
Answer: Not recommended!
The threads may be damaged after removal and may become loose after reinstallation
Why do screws slip on metal keel?s?
Coarse threads may be used by mistake (should be fine threads/S-type).
Metal keels are too thick (over 20 gauge), self-tapping screws or pre-drilling are required.
The electric drill has insufficient torque, change to a higher-power tool
What should I do if a screw pops out after installation?
Remove the protruding screw and clean the hole. Install a new screw near the original hole (distance ≥ 2 inches).
Will Bugle Screws rust? How to prevent rust?
Standard version: Black phosphate coating is suitable for dry indoor environments.
Rust-proof version: Choose zinc-plated or nickel-plated drywall screws (for wet areas such as bathrooms and basements).
Maintenance advice: Check the screw heads annually in wet areas and replace them if they are severely rusted.
What should I do if the screw head protrudes or is too deep after installation?
What should I do if the screw head protrudes or is too deep after installation?
A: Use a tool to screw it back in, or replace it with a shorter screw
Too deep: Use a light putty to fill the hole and install a new screw nearby.
Can I use a Bugle Screw to hang heavy objects (such as cabinets)??
No! The Bugle Screw is only for fixing drywall and is not load-bearing.
To hang heavy objects, use Drywall Anchors or structural screws that are fixed directly to the keel.
Can ordinary screws be used instead of bugle head screws?
The bugle head design of drywall screws cannot be replaced!
