Description
SINODRILLS Self-Drilling Anchor Coupling
Self drilling anchor couplings are used to link anchor bars to make the anchor longer, thus promote its installation depth.
Features
• Stable quality;
• Thread is compatible with ISO and other international standards;
• Precision-manufactured anchors with ≤ 0.25 mm tolerance;
• Good mechanical performance.
Applications
Pre-supporting, micropiling for foundation underpinning, slope anchorage, etc.
