What types of fasteners does YH Fastener manufacture?

We manufacture machine screws, self tapping screws, sealing screws, shoulder screws, sems screws, captive screws, security screws, nylon patch screws, carbide insert screws and set screws, plus hex keys, Torx keys and spring and ball plungers, in both standard and custom versions.

Can you produce non-standard screws from my drawings?

Yes. Our engineering team reviews 2D drawings, 3D models or physical samples, confirms material, head style, drive, thread and finish, and then builds tooling for cold heading and thread rolling. Non-standard and international-standard parts are both supported.

Which quality certifications does your factory hold?

Our production system operates under ISO 9001, ISO 14001 and IATF 16949. Every batch passes multi-stage inspection from incoming wire rod to final packing, and inspection records can be provided with shipments.

How do you prevent screws from loosening under vibration?

Depending on the application we recommend pre-applied nylon patches, sems screws with captive washers, or shoulder and sealing designs. The right solution is selected based on joint material, required re-use cycles, torque and operating temperature.

Do you export to my country and how do I start a project?

YH Fastener ships to more than 60 countries. Request our catalog or contact our sales engineers with your drawing, quantity and target application, and we will reply with a technical review within 24 hours.

Product Description

Self-tapping screws are efficient, all-purpose fasteners for furniture, construction, electronics and automotive applications. Unlike ordinary screws, they need no pre-drilled threads or nuts, completing drilling, threading and locking in one step to save installation time and labor costs.

Featuring sharp tips and precision triangular threads, our screws can cut firm threads on wood, plastic, iron and aluminum sheets. They grip tightly and resist loosening from vibration, ensuring stable long-term fastening performance.

We offer two practical material options for different scenarios:

Carbon Steel Screws

Hardened for high torsion resistance, effectively preventing slipping and breakage. Multiple finishes like white zinc, color zinc and nickel plating provide good anti-rust protection. Cost-effective and perfect for indoor dry environments, including furniture and electrical assembly.

304 Stainless Steel Screws

Boasting excellent rust and corrosion resistance, these screws withstand humidity, rain, outdoor exposure and salt fog. Ideal for outdoor projects, kitchen and bathroom equipment and other harsh working environments.

Available in various head types: pan head, countersunk head, hexagonal head and flange head, fitting different flat and hidden installation needs. Standard cross grooves suit common screwdrivers for easy operation. Sharp pointed tips fit soft materials, while drill tail tips work perfectly for 0.5-2mm thin metal sheets.

Full ST specifications (ST2.2-ST6.3) and 4mm-80mm lengths are in stock. Custom sizes and threads are supported. Factory direct supply with stable quality, fast delivery and support for small trial orders, suitable for global wholesale and engineering procurement.

Frequently Asked Questions

1. What substrates are these self-tapping screws suitable for?

With sharp tips and triangular threads, they cut reliable threads into wood, plastic, iron, and aluminum sheets. For thin metal sheets between 0.5mm and 2mm, drill tail tips are specifically recommended.

2. What are the key differences between Carbon Steel and 304 Stainless Steel screws?

Carbon steel screws are hardened for high torsion resistance with anti-rust plating (white zinc, color zinc, nickel), making them cost-effective for indoor dry environments. 304 stainless steel offers superior corrosion protection against humidity, rain, outdoor exposure, and salt fog.

3. Which head types and drive styles are available?

We supply pan head, countersunk head, hexagonal head, and flange head options to accommodate exposed or concealed installations. All feature standard cross grooves suitable for conventional screwdrivers.

4. Do self-tapping screws require pre-drilling or nuts?

No pre-drilled threads or mating nuts are needed. They complete the drilling, thread-forming, and locking process in a single motion, significantly reducing installation time and overall labor costs.

5. What size specifications are currently in stock?

Standard specifications ranging from ST2.2 to ST6.3 with lengths between 4mm and 80mm are kept in stock. Custom sizes, specific dimensions, and specialized threads can also be produced on demand.

6. Can I place small trial orders for wholesale evaluation?

Yes. As a direct factory supplier, we accommodate small trial orders for evaluation alongside full-scale bulk engineering procurement and global wholesale distribution.
