Woodworking Self-Drilling Screws with Serrated Underside | Hetai
Specialized Self-Drilling Screws for Woodworking Applications
Hetai manufactures Woodworking Self-Drilling Screws with Serrated Underside, combining a sharp self-drilling point with a specially designed serrated structure beneath the screw head.
Designed for furniture manufacturing, woodworking, cabinetry, wooden structures, and other wood-related applications, these custom screws provide efficient installation together with enhanced engagement between the screw head and the workpiece.
Serrated Underside for Enhanced Grip
The key feature of this screw is the serrated underside beneath the head.
The serrated structure creates multiple contact points when the screw is tightened, helping the screw head grip the material more securely. This design can help reduce unwanted rotation of the screw during installation and improve fastening stability.
The geometry of the serrations can be customized according to the application, including the number, height, width, and shape of the serrated edges.
Self-Drilling Screw Design
The screw is equipped with a specially formed self-drilling point, allowing it to penetrate the material efficiently during installation.
Combined with the serrated underside, the screw provides a specialized fastening solution where both efficient penetration and secure head engagement are required.
The tip geometry, thread design, and head configuration can all be customized to achieve the required fastening performance.
Custom Manufacturing by Hetai
As an experienced manufacturer of custom fasteners and non-standard screws, Hetai can manufacture these woodworking self-drilling screws according to customer drawings, samples, specifications, or application requirements.
Customization options include:
- Screw diameter and length
- Head diameter and height
- Serration number and geometry
- Serrated underside profile
- Self-drilling point design
- Thread diameter and pitch
- Thread length
- Drive type
- Material and grade
- Surface treatment
For special applications, Hetai can also develop customized head and tip configurations based on the customer’s requirements.
Materials and Surface Finishes
Depending on the application, Hetai can manufacture these screws from carbon steel, alloy steel, stainless steel, and other suitable materials.
Available surface treatments may include:
- Zinc plating
- Black oxide
- Nickel plating
- Chrome plating
- Electrophoresis
- Customized surface finishes
Material and surface treatment can be selected according to the required strength, corrosion resistance, appearance, and working environment.
Precision Manufacturing Process
Hetai combines advanced manufacturing processes to ensure consistent product quality.
A typical production process may include:
Cold Heading → Thread Rolling → Tip Processing → Serrated Underside Processing → Surface Treatment → Quality Inspection → Packaging
Cold heading forms the screw body and head efficiently, while thread rolling produces accurate and consistent threads. Specialized secondary processing is then used to create the required self-drilling tip and serrated underside.
Each production stage is carefully controlled to maintain dimensional accuracy and batch-to-batch consistency.
