Steel Stud Drywall Screw Manufacturer & Global Supplier
Steel Stud Drywall Screws are drywall screws designed for connecting light steel keels (Metal Studs), galvanized steel frames and gypsum boards (Drywall). The surface is galvanized or phosphated, rust-resistant and corrosion-resistant. They are suitable for commercial buildings, indoor partitions and ceiling projects. Its self-drilling tip and fine thread ensure rapid penetration of metal frames, provide a firm bite, and reduce construction time and costs.
Core Features Of sheetrock screws for metal studs
Rust-proof and corrosion-resistant, suitable for harsh environments
Galvanized layer (4μm): Passed ASTM B633 standard test, resistant to salt spray corrosion, suitable for high humidity areas such as bathrooms and basements
Optional Dacromet coating: Special for outdoor projects, corrosion resistance increased by 300%.
Self-drilling design, efficient installation
Patented tip: No need for pre-drilling, directly penetrate 22-25 light steel keels (0.5-1.2mm thickness).
Fine thread + deep groove: Enhance metal bite force, tensile strength of 200kg/piece (#8×25mm specification).
High-strength material, resistant to bending and breaking
Heat treatment of low carbon steel (HRC 50-55): hardness increased by 40%, bending rate <0.5%.
Wide compatibility
Applicable tools: electric screwdriver (PH2 bit), impact drill (hexagonal head).
Zinc plated fine thread

Applicable Scenarios Of Gypsum Screw For Metal
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.
Tool Settings
Electric screwdriver speed: 2000-2500 RPM, torque: 4-5Nm (avoid thread slip).
Pre-drilling holes for light steel keels (only for ultra-thick steel): the hole diameter is 75% of the screw diameter.
Installation specifications
Screw spacing: ≤15cm at the edge of the keel, ≤30cm in the middle area.
Countersunk depth: embedded in the surface of the gypsum board ≤1mm, ensure that the putty covers the surface evenly.
Precautions
Avoid direct contact with stainless steel (electrochemical corrosion), and use insulating gaskets.
Outdoor engineering screws need to be sealed with silicone to extend the anti-rust life.

FAQ
Q1: Can Steel Stud Screws be used on wooden keels?
A1: Yes, but it is recommended to use coarse thread types (such as #6×32mm) for better grip
Q2: How long is the life of galvanized screws in a salt spray environment?
A2: Standard galvanized types are about 5-8 years, and Dacromet coated types can reach more than 15 years (regular maintenance).
Q3: How to choose the screw length?
A3: Formula: Screw length = gypsum board thickness + keel embedment depth (at least 12mm).
