Tyta Resin Rock Bolts

Tyta bolts are made with larger threads that extend the useful life of the bolt, and allow the bolt to be re-tightened as needed.

Rock bolt assemblies with extended-length coarse thread, for multiple re-tightening after installation with resin capsules. Assemblies comprise the stud, matching nut and bearing plate washer, in a variety of bolt diameters and lengths. Rock bolt assemblies are packaged as complete, ready-to install units.

The stud portion of the Rock Bolt Assembly comprises a deformed steel bar with a cold-rolled thread at one end.
The Tyta Bolt has a 6mm pitch knuckle thread, with proprietary form, from lengths of 200 mm up to a maximum of 500 mm in length.
