Coarse Thread Black Phosphate Drywall Screws for Wood Stud Projects

Choose coarse thread screws when the substrate is wood framing

For drywall projects using wood studs, coarse thread is the correct specification because the thread profile is designed to grip wood framing securely. At JLHY, we produce coarse thread black phosphate drywall screws for drywall-to-wood-stud installation in residential and commercial construction. If your project uses thin gauge steel studs, you should request our fine thread drywall screw variants instead, because coarse thread is not the intended option for that application.

The product is built around standard site installation practice: carbon steel construction, black phosphate finish, bugle head, Phillips drive and a sharp point that starts quickly without predrilling. The bugle head seats flush without tearing the drywall paper, helping installers achieve a clean board surface across walls and ceilings.

Specification points to confirm before quotation

To prepare an accurate inquiry, you should define the screw size around board thickness, fastening depth and project installation method. Our available specification range covers gauges from #6 to #12 and lengths from 25mm to 75mm.

• Material: Carbon steel
• Finish: Black phosphate
• Thread: Coarse thread
• Head type: Bugle
• Drive: Phillips
• Application: Drywall to wood studs
• Gauge range: #6–#12
• Length range: 25–75mm

These screws are compatible with standard Phillips-drive drywall guns, which supports fast and consistent installation on larger wall and ceiling areas. We manufacture them with controlled hardness so the screws thread cleanly without brittle fracture, and each batch is tested for consistent drive performance.

Application fit for contractors, distributors and importers

For contractors and procurement managers, the main technical filter is the framing material. Use this coarse thread version for wood studs where strong thread engagement is required. For distributors and importers, the practical stocking decision is to carry the gauge and length mix that matches common board and framing requirements in your market.

The black phosphate finish provides a clean appearance with reliable indoor corrosion resistance. It is intended for indoor drywall fastening applications, not as a substitute for a project-specific exterior or high-corrosion coating requirement.

Batch control and supply planning

At JLHY, we support industrial and construction-channel procurement with production capacity exceeding 50,000 boxes per day. We provide full batch traceability and material documentation for these drywall screws, helping your purchasing and quality teams keep order records organized across repeat shipments and project supply.

For larger procurement programs, share the required gauge, length, estimated quantity and target application when you contact us. That allows us to discuss specifications, volume pricing and samples based on the actual fastening requirement.

Packing and RFQ details to include

When you send an RFQ, include any packing instructions your market or distribution channel requires, along with the screw specification. The confirmed quotation should align the product size, quantity, documentation requirement and sample request before order placement.

• State the application clearly: drywall to wood studs.
• List required gauge and length, such as #6–#12 and 25–75mm within our available range.
• Confirm whether samples are needed for installation evaluation.
• Share estimated order volume so we can discuss volume pricing.
• Include packing expectations for quotation confirmation.
