Posimix Bolt
- -Available in left-hand or right-hand thread.
- -Higher thread ribs compared to other bars,mix resin better and improve anchorage.
- -Suitable for use with either resin cartridges or cement grout.
- -It has equal strength on the entire length.
- -Due to continuous thread on the entire length, the nut can be fastened upward at any place. This will increase the material utilization ratio and save cost.
Posimix Bolt Functions
Posimix Bolt features a high-strength metal bolt body, continuous threads rolled throughout the entire length, specially designed spring wire attached to the up-hole end ensures that the resin components are thoroughly combined and distributed evenly and uniform strength throughout the length. The fastening end is equipped with prestressed washers and ball-shaped nuts, which makes it material-saving, labor-saving, and uniform strength.
The Posimix Bolt designed by Tonry for the metalliferous mining have been supplied in mines for many years and have been recognized by customers.Together with a torque dome nut, supplied as standard, it represents state of the arttechnology in the one step installation of roof bolts for mining,tunneling and strata reinforcement.
