Posimix Dynamic Bolt Functions
The main body of the Posimix Dynamic Bolt is a full thread bar bolt, with the top end coiled into a spring shape using steel wire. The spring-shaped steel wire can thoroughly mix the resin. Installation is quick and convenient, providing stable support for the rock strata. A plastic sheath can be fitted over the middle section to provide dynamic capabilities to the spring bolt.
