                All Thread Bar Bolt

                                

                 

                 

                Technical Merits:

                 

                 

                 

                Features:

                The high deformation thread bar provides good load transfer between bolt and resin (cement).
                Continuous thread over the bar length provides high flexibility in fragile entry surface and blasting conditions as the bolt can be readily re-tensioned.
                Utilization of Lock washer (Optional) can effectively prevent bolt load bleeding due to the fragile entry surface and blasting.
                Typical Lab pull test shown in Figures.

                Hot rolled with high continuous deformation over entire bolt length
                Coarse left hand thread with 10mm(8mm) pitch
                Dome plate and lock washer (optional)
                Resin anchor or cementation grouts
