A 4.2 mm self-drilling screw that cuts a clean hole through a 2 mm steel bracket will spin in place on a 0.8 mm cladding panel, and the same screw that holds a dry indoor ceiling together can rust to the surface within a season on a coastal roof. Neither failure is a manufacturi...
READ MOREA technician presses the point of a pan-head screw against a 1.5 mm galvanised bracket, leans into the driver, and squeezes the trigger. Two seconds later the joint is tight. No nut, no weld and no pre-cut thread were involved: the screw created its own thread inside the steel a...
READ MOREA production manager once asked us to replace a bugle-head wood screw with a countersunk screw because the drawing said "flat head." The first trial run failed: the flat-head screws sat proud, split several panels, and slowed the line until the pilot hole was changed. That one h...
READ MOREAs a dedicated Carbon Steel Wood Screws manufacturer and supplier, Anhui Linghong Hardware Technology Co., Ltd. produces high-performance fasteners for furniture, construction, and timber structures. Our screws are cold-headed from premium carbon steel (e.g., 1022A) and carburized for a hard case with a tough core, delivering strong pull-out resistance and reliable driving performance.
We offer a wide range of head styles, drive systems, thread forms, and surface finishes to match your specific application—from indoor furniture assembly to outdoor decking and coastal environments. With over 80 production lines and a monthly capacity of 500 tons, we support both standard and custom projects with consistent quality and timely delivery.
Our carbon steel wood screws are available in several head and drive configurations, each suited to different installation needs. The table below outlines common types and their typical uses.
| Head Style | Drive Type | Typical Applications |
|---|---|---|
| Countersunk (flat) | Phillips, Pozidriv, Square, Torx | Furniture, cabinetry, decking (flush finish) |
| Bugle head | Phillips, Torx | Drywall, sheathing, paneling |
| Hex head | External hex, with washer | Timber framing, heavy construction |
| Pan head | Phillips, Torx | General woodworking, metal-to-wood |
| Wafer head | Phillips, Torx | Chipboard, MDF, particleboard |
| Button head | Hex socket, Torx | Aesthetic exposed fastening |
We also produce self-drilling variants with a cutting tip for metal-to-wood or wood-to-wood without pre-drilling. For collated applications, our screws can be supplied on strips for auto-feed screwdrivers, improving installation speed on production lines.
We use low-carbon steel wire such as 1022A, which is cold-headed to shape and then carburized. This creates a hard surface layer (typically 550–750 HV) for thread cutting and wear resistance, while the core retains ductility to prevent brittle failure under torque. Our heat treatment is precisely controlled to meet hardness and case depth specifications for each screw size.
For demanding applications, we can adjust core hardness or case depth based on the substrate (softwood, hardwood, engineered wood) and the required pull-out strength. Our engineering team reviews the material and working point to recommend the optimal thread design—sharp, twin-fast, or hi-lo—for your specific wood density.
Corrosion resistance is critical for wood screws, especially in outdoor or humid environments. We offer three main coating systems, each with distinct performance characteristics:
We also apply other finishes such as black phosphate, blue-white zinc, or custom colors (e.g., white-painted heads) to match your product aesthetics. Our coating lines are monitored to ensure uniform thickness and adhesion, and we can provide salt-spray test reports upon request.
Our factory is ISO 9001, ISO 14001, and ISO 45001 certified. We operate a full-process quality control system, starting with first-piece inspection, in-process patrols, and final ex-factory checks. Our lab is equipped with metallographic polishing machines and Rockwell hardness testers to verify case depth and core hardness. We also conduct torque tests, pull-out tests, and salt-spray tests to ensure performance meets your specifications.
Each batch is traceable, and we maintain records of material certificates and heat-treatment logs. For critical projects, we can provide inspection reports and certificates of conformance.
We understand that off-the-shelf screws may not fit every project. Our engineering team works with you to customize dimensions, head styles, drive types, thread geometry, and coatings. We can also develop special features like ribs, serrations, or type-17 points to reduce splitting or improve holding power in specific woods.
With over 20 years of fastener experience, we provide design-for-manufacturing advice to optimize performance and cost. We support OEM and ODM projects, from prototype to mass production.
To prepare an accurate quotation and sample, please provide the following details:
Our sales engineers will confirm technical feasibility and provide a detailed specification sheet before production.
We have a complete packaging system that supports various requirements: small retail boxes, bulk cartons, palletized loads, or collated strips. Our export experience ensures proper labeling and documentation for international shipping. With a monthly capacity of 500 tons, we can handle large orders with consistent lead times.
Electroplated zinc provides a thin, bright coating but can cause hydrogen embrittlement in high-strength screws. Mechanical zinc plating is a cold-weld process that eliminates hydrogen absorption, making it safer for critical connections. It also offers better corrosion resistance.
Yes, we can match RAL or Pantone colors for painted heads or apply custom coatings like black oxide or Dacromet. We will confirm the exact finish based on your sample or specification.
For standard sizes, we can ship within 2-3 weeks after order confirmation. Custom products may require 4-6 weeks for tooling and sample approval. We will provide a precise schedule with your quotation.
Yes, we offer free samples for standard products. Custom samples are available at a nominal cost, which is deducted from the production order. Please allow 5-7 days for sample preparation.
We follow a strict QC plan: first-piece inspection, in-process checks every hour, and final random inspection before packing. We also provide inspection reports and can arrange third-party testing if required.
Our portfolio also includes Products, Wood Screw, Stainless Steel Wood Screws for applications with different operating ranges, interfaces or integration requirements.
