Resin Bolt
- -Resin Bolt is made of hot rolled rib bar. which has great anchoring effect and can be cut according to demands.
- -Usually combined with star plates, provides anchoring force for rock strata.
- -Resin Bolt undergoes very stringent tensile testing to ensure product quality.
- -Provide customers with a pull test for Resin Bolt after installation.
Resin Bolt Functions
Resin Bolt features a high strength metal bolt body, continuous threads rolled throughout the entire length, and uniform strength throughout the length. The fastening end is equipped with prestressed washers and ball shaped nuts, specially designed spring wire attached to the up-hole end ensures that the resin components are thoroughly combined and distributed evenly. It is simple and low cost, widely used in coal mines, railway tunnels and other types or roadway projects.
Resin Bolt Features & Advantages
Available in left hand or right hand tread.
Higher thread ribs mix resin better and improve anchorage.
Suitable for using with either resin cartridges or cement grout.
It has equal strength on the entire length.
Due to continuous thread on entire length. the nut can be fastened upward at any place. This will increase the material utilization ratio and save cost.
Available in black or hot dip galvanized.
