hot rolled thread bar

Hot rolled with high continuous deformation over entire bolt length Coarse left hand thread with 10mm(8mm) pitch

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.
