Key Features & Technical Specifications
- Black Phosphate Coating: Provides excellent corrosion resistance, extending service life in humid environments. The coating also reduces friction during driving, allowing smoother installation.
- High Hardness (HRC 45-50): Manufactured using high-quality carbon steel and precise heat treatment, the screws achieve a hardness level that prevents snapping and deformation, ensuring a secure connection even under repeated stress.
- Sharp Self-Drilling Point: The sharp point enables quick penetration into metal studs without pre-drilling, saving time and labor on site.
- Double Coarse Thread: Designed for fast driving and strong holding power in thin metal, the double thread reduces installation torque and minimizes the risk of stripped threads.
- Bugle Head with Phillips Drive: The bugle-shaped head sits flush with the drywall surface, allowing easy taping and finishing. The Phillips drive ensures positive engagement with screwdrivers, reducing cam-out.
- No Snapping Guarantee: Each screw is rigorously tested to ensure it can withstand high torque without snapping, providing peace of mind for contractors working in tight schedules.
- Versatile Length Options: From 13mm for single-layer drywall to 100mm for multi-layer or insulation-backed systems, we offer a comprehensive range to suit various panel thicknesses and stud gauges.

Frequently Asked Questions (FAQ)
-
Can these screws be used for wood studs?
These screws are specifically designed for metal studs. While they can be used for softwood in some cases, we recommend using special wood screws for optimal performance in wood. -
What is the maximum metal thickness they can penetrate?
The screws can penetrate metal studs up to 1.2mm (18 gauge) without pre-drilling. For thicker steel, pre-drilling is recommended. -
Are these screws suitable for outdoor use?
The black phosphate coating provides moderate corrosion resistance. For prolonged outdoor exposure, we recommend our stainless steel or coated variant (available upon request). -
How do I choose the right length?
Select a length that is at least 13mm longer than the total thickness of the drywall and any insulation. For example, for a single 12.5mm drywall, use a 25mm screw. -
Do you offer smaller packaging or bulk options?
Yes, we offer custom packaging from small retail boxes to bulk cartons. Please specify your needs when ordering. -
Is there a minimum order quantity (MOQ)?
Our standard MOQ is 10 cartons per size, but we can accommodate trial orders for sample evaluation. -
How are the screws packed to prevent damage during shipping?
We use sturdy corrugated cartons with internal dividers or plastic trays to keep screws organized and protected. -
Can I get a sample before placing a bulk order?
Absolutely. We provide free samples for up to 5 pieces per size, with the buyer covering shipping cost. Contact our sales team for details.
