Description:
Self drilling anchor bolt adopts wave-thread hollow bar, which has great anchoring effect and can be cut according to demands. Sinorock also produces large-diameter self drilling anchor bar by adopting advanced equipment and technology.

We're here to help: Easy ways to get the answers you need.

Introduction

Self drilling anchor bolt is composed by hollow anchor bolt, anchor nut, anchor plate, anchor coupler, drill bit, centralizer, and the hollow anchor bars can be cut and lengthened by coupling on request.

Functions:
Self drilling anchor system is an advanced system which can ensure the anchoring effect for complex ground conditions. It can be integrated with the functions of drilling, grouting and anchoring.

Conditions:
• Tunneling
• Mining
• Slope Stabilization
• Foundation Support

Features and advantages:
1. Safe, reliable, and time saving.
2. Simple installation & operation.
3. Choice of drill bits for different ground conditions.
4. Grouting works synchronize with drilling or after drilling. Grout can fill fractures effectively.
5. Anchor bars can be cut and lengthened on request, applying to narrow spaces.
6. It provides higher bonding stress than smooth steel pipe depending on continuous wave thread.
