Products Description
Self Drilling Screws are threaded fasteners featuring a drill-point tip that allows them to drill a pilot hole, tap threads, and fasten materials-such as metal, wood, or plastic-in a single operation during installation. Designed for applications requiring rapid, efficient, one-step installation, they are widely used in steel construction, metal roofing and wall cladding, equipment installation, automotive manufacturing, and general industrial assembly; by consolidating drilling, tapping, and fastening into one process, they significantly boost assembly efficiency while reducing tooling and labor costs.
Detailed Specifications
| Optimized Flute Geometry | Flutes with specific volumes and helix angles are designed for different materials of Thread-Cutting Screw (such as high-strength steel or human cancellous/cortical bone) to prevent heat accumulation and chip jamming during hole formation. |
| Graded Tolerance Control | Industrial-grade products strictly adhere to ISO/DIN standards, while the thread tolerances of medical-grade Thread-Forming Screw are controlled at the micron level to ensure clear torque feedback during tightening. |
| Low-Friction, Wear-Resistant Coatings | Surfaces of Self-Piercing Screw can be finished with specialized lubricating coatings (such as industrial Dacromet or Teflon, or medical-grade ultra-thin passivation layers) to reduce transient frictional resistance during installation significantly. |
Product Advantages
Eliminates pre-drilling
Saves 1–2 seconds of drilling time per Tapping Fastener, resulting in significant labor cost savings for installations involving thousands of screws.
01
Higher positioning accuracy
The drill point resists slipping upon contact with the base material, resulting in less positional deviation compared to the two-step method of drilling followed by driving.
02
Reduces tool changes
Eliminates the need to switch between a drill and a screwdriver; the entire operation is completed with a single tool for the Thread-Forming Screw.
03
No risk of thin-sheet deformation
When used on thin steel sheets (0.5mm–1.5mm), the cutting action of the drill point causes less sheet bulging than the impact forces associated with Thread-Cutting Screw.

Product Customization Process
Q: What surface treatment options are available for the Self-Piercing Screw?
A: Default is electroplating, with Dacromet coating or hot-dip galvanizing available. All options comply with RoHS requirements regarding lead and cadmium content.
Q: What thickness of steel plate can a Tapping Fastener penetrate? How is their drilling capacity determined?
A: Drilling capacity depends on the screw's diameter, the hardness of the drill point, its geometric design, and the strength of the steel plate. To determine the drilling capacity, refer to the maximum drilling thickness specified in the product datasheet, which is based on standard testing conditions. In actual applications, factors such as steel plate strength and surface coatings should be considered, and the rated capacity should be appropriately derated.
Q: What's your delivery time for the Thread-Cutting Screw?
A: About 10-15 days for samples, 10-15 days for mass production.
Q: What are your terms of payment?
A: Usually, we accept bank T/T and irrevocable L/C at sight; for regular orders, we prefer 30% in advance, 70% balance before shipment.
