As an effective means of anchoring, self drilling anchor bolt can be widely used in advanced support, radial support, slope reinforcement, roadbed reinforcement and tunnel disease control.
Self-drilling anchor (SDA) combines drilling, insertion and grouting into one easy operation. It reduces project lead time and installation difficulty.Low carbon content in steel increases its ductility, reduces its brittleness, and resists corrosion cracking and carbon embrittlement.

This Choice Of Material Significantly Reduces Occurrences Where Rockbolt May Snap Or Buckle During Onsite Installation.
As An Effective Means Of Anchoring, self Drilling Anchor Bolt can Be Widely Used In Advanced Support, Radial Support, Slope Reinforcement, Roadbed Reinforcement And Tunnel Disease Control.
Structure:
1) Ball Nut: It Can Transfer The Stress Of Surrounding Rock To The Pad.
2) Arch Plate: Can Bear Greater Stress Of Surrounding Rock.
3) Check Plup Plug: Make The Grouting Maintain A Certain Pressure To Fill The Surrounding Rock Gap Adequately.
4) Anchor Bolt Bar: The Whole Length Of The Intermational Standard Waveform Connection Thread, Easy To Install Drill Bit, Coupling Sleeve, Fastening Nut; And Can Be Arbitrarily Cut And Connected To Lengthen.
5) Bushing: So That The Bolt Can Be Lengthened To The Design Depth While Drilling.
6) Broach: It Has Strong Penetrating Power, Enabling The Bolt To Pass Through All Kinds Of Rocks.
Characteristic:
Self Drilling Bolt Adopts Good Thick Wall Seamless Steel Pipe Material, Perfect And Fast Surface Screw Forming Technology And Well-made Fittings, The Function Of Drilling, Grouting And Anchoring Has Been Realized.
1) There Have A Strong Penetrating Drill In Front Of The Bolt, Under The Action Of General Drilling Machinery, It Can Easily Penetrate All Kinds Of Rocks.
2) The Bolt Has A Continuous International Standard Corrugated Thread, Which Can Be Used As A Drill Pipe To Complete The Drilling Of Anchor Hole.
3) The Bolt Body As The Drill Pipe Does Not Need To Be Pulled Out, And The Cavity Can Be Used As The Grouting Channel From Inside To Outside.
4) Hign Efficiency Grouting Stopc Ock Enables Grouting To Maintain Strong Grouting Pressire, Fully Fill The Vold And Fix The Fractured Rock Mass, High Stength Washer And Nuts Can Transfer The Stress Of Deep Surrounding Rock Evenly To Surrounding Rock, The Purpose Of Mutual Support Between Rock And Anchor Is Achieved.
