We are Hefei SENOTECH New Materials Co., Ltd, a dedicated trading company specializing in high-performance fasteners for the construction and drywall industry. With an annual export value exceeding US$1 million and a global footprint spanning North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, we bring reliable sourcing and rigorous quality control to every order. Our 13mm-100mm Full Sizes Available Wallboard Screws Fine Thread Zinc Plated for Metal Studs are engineered to meet the demands of professional contractors who require consistent strength, easy driving, and zero snapping during installation. Whether you need a small batch for a renovation project or a full container for a large-scale construction, our product delivers unwavering performance.
These screws are specifically designed for metal studs and light-gauge steel framing. The fine-thread profile ensures maximum holding power and reduces the risk of strip-out, while the zinc-plated finish provides reliable corrosion resistance in indoor environments. Every screw undergoes strict hardness testing to achieve a balance between high hardness (to penetrate steel studs effortlessly) and controlled ductility (to prevent brittle snapping). The result is a fastener that drives smoothly, seats flush, and stays securely anchored over time.
Product Features & Technical Specifications
- Full Size Availability – Lengths from 13 mm to 100 mm cover virtually all drywall and paneling needs, allowing one-stop sourcing for different stud thicknesses and board layers.
- Fine Thread Design – The sharp, closely spaced threads cut into steel studs with minimal force, creating a strong mechanical bond that resists pull-out under vibration or load.
- Zinc Plated Finish – A uniform electro-galvanized coating offers moderate corrosion protection suitable for interior applications, extending the service life of the fastener without adding excessive cost.
- High Hardness, No Snapping – Our proprietary heat-treatment process achieves a surface hardness of HRC 45-50 (core hardness controlled for toughness), ensuring the screw penetrates steel studs without bending or breaking, even with repeated driving.
- Bugle Head & Phillips Drive – The countersunk bugle head compresses the drywall paper for a clean dimpled finish, while the deep Phillips recess provides positive driver engagement to reduce cam-out and increase installation speed.
- Consistent Geometry – Every screw is manufactured to tight tolerances, with uniform thread pitch, head diameter, and point angle for predictable performance across all lengths.

Frequently Asked Questions
Q1: What material are these screws made from?
A1: They are manufactured from high-quality carbon steel (typically C1022 or equivalent) with a controlled heat treatment to achieve the required hardness and toughness.
Q2: Can these screws be used in wood studs?
A2: While they are optimized for metal studs (fine thread design), they can also be used in hardwood or plywood with pre-drilling. For wood-to-wood applications, a coarse thread screw is more appropriate.
Q3: Are the screws rust-proof?
A3: The zinc plating provides good corrosion resistance for indoor dry conditions. For outdoor or high-humidity environments, we recommend additional coating options such as yellow zinc or anti-corrosion treatment (available upon request).
Q4: What is the typical hardness value?
A4: The surface hardness is HRC 45-50, while the core is kept slightly softer to prevent brittleness. This balance ensures easy penetration without snapping.
Q5: Do you offer custom lengths beyond 100 mm?
A5: Yes, we can produce longer lengths (up to 150 mm or more) for special applications. Minimum order quantity may apply for custom sizes.
Q6: What packaging options do you have?
A6: Standard packing is 1,000 pieces per box, with 10 boxes per carton (10,000 pieces per carton). We also offer bulk poly bags, shrink-wrapped bundles, or private-label boxes with your brand.
Q7: Can you provide a sample before bulk order?
A7: Certainly. We offer free samples (within reasonable quantity) with freight collected. You can test the driving performance, hardness, and finish before placing a larger order.
Q8: What is the lead time for a 20-foot container?
A8: Typically 25-35 days after order confirmation and deposit. For urgent orders, express production may be arranged with a slight premium.
