T Thread Self Drilling Anchor Manufacturer
What's T Thread Self Drilling Anchor?
A T-Type self drilling hollow grout anchor is a fully threaded, hollow steel anchoring system designed for simultaneous drilling, grouting, and anchoring in unstable ground conditions.
The T-thread profile is widely used in international projects due to its simple structure, good compatibility, and cost efficiency, making it a popular choice for large-volume procurement and distributor supply.
Key benefits of T Thread anchors:
- Easy installation and assembly on site
- Compatible with common nuts, couplers, and plates
- Cost-effective solution for large-scale projects
- Suitable for temporary and permanent applications
- No pre-drilling required in unstable ground
SDA System Components
- 01 Hollow Anchor Rod: Threaded hollow steel rod used for drilling, grouting, and permanent anchoring with high tensile .
- 02 Drill Bit: Sacrificial drill bit for efficient penetration, available in cross, button, or clay types matched to anchor size.
- 03 Centralizer: Steel plate distributing anchor load evenly to the supported structure or ground surface.
- 04 Coupler: Threaded steel coupler connecting anchor rods to achieve greater drilling depth and continuous load transfer.
- 05 Anchor Nut: Heavy-duty threaded nut securing the anchor system after installation and ensuring reliable load transmission.
- 06 Anchor Plate: Cement-based grout injected through the hollow core to bond surrounding ground and provide corrosion protection.
