Posimix Bolt for Roof Support Functions
The system is specifically engineered for secure installation of rock bolts in underground mining and tunneling environments.Posimix Bolt features a high strengeth metal bolt body,continuous threads rolled throughout the entire length,apecially designed spring wire attached to the up hole end ensures that the resin components are throughly combined and distributed evenly.It represents state of the art technology in the one step installation of roof bolts for mining,tunnel and strata reinforcement.
Posi Bolt Features & Advantages
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.
