When you need fasteners for thin materials, unstable loads, or corrosion-sensitive environments, choosing the wrong screw can lead to cracking, deformation, or assembly failures. Flat head screws wholesale from a reliable manufacturer help you secure plastic, wood, thin metal, and industrial components with consistent performance.
Shenzhen Shenhu Fasteners Industrial provides JIS B1111-1996 large flat head screws designed for efficient installation and long-term reliability. With over 40 years of fastener manufacturing experience, Shenhu delivers stainless steel and coated screw solutions for electronics, appliances, machinery, automotive, and other demanding industries.
Flat Head Screws Wholesale with JIS B1111-1996 Standard Design
The JIS B1111-1996 large flat head screw features a wide, thin umbrella-shaped head that improves load distribution. Unlike standard small-head screws, this design increases the contact area by approximately 1.5–2 times the thread diameter, reducing stress concentration on soft materials.
You can use these Phillips flat head screws without pre-drilled countersinks or additional washers, which simplifies assembly and improves production efficiency.
Key product advantages include:
- Wide load-bearing head design to protect plastic, wood, and thin metal surfaces
- Phillips cross-slot drive for manual and automated installation
- M2–M16 size range with 5–100 mm length options
- Custom thread and size solutions available for specific applications
- Stainless steel and coated steel options for different environments
Stainless Steel Flat Head Screws for Industrial Applications
Shenzhen Shenhu Fasteners produces these large flat head machine screws using MLO8AI low-carbon steel, SUS304 stainless steel, and SUS316 stainless steel. These materials support different strength and corrosion resistance requirements.
The screws are suitable for industries where stable fastening performance matters:
