The shell anchor eliminates resin wait times and provides high pre-tension along the entire length of the bolt.Using manufacturing equipment of its only kind in Australia, we utilise a 20.4mm diameter Extra High Tensile J- profile bar to make the best INSTàL bolt in the country.
The INSTàL Bolt is the solution to reduced bolting cycles to increase roadway development rates.
Only patented system using "expansion shell-shear pin"concept.
- Uses mechanical shell and resin for greater anchorage.
- Complete installation in eight seconds or less.
- Single spin cycle in one direction.
- Shear pin in expansion plug delays expansion of shell until resin mixes.
- Increased anchorage capacity; torque bleed-off minimized.
- Support power of mechanical bolts and resin combined for increased anchorage.
The INSTàL is available as a 2 and 3 piece bolt for use in low seam heights.
