It is a self-drilling rock bolt that can be used as a lock bolt without modification.
Rock bolts are widely used in tunnel support work and slope reinforcement work in mountainous areas. Among these, particularly in cases where the ground does not support the hole walls or on steep slopes, self-drilling rock bolts that can be used directly as rock bolts with drilling rods have become popular to improve workability. Esty Engineering Co., Ltd. has recently completed the development of the self-drilling rock bolt "SP Anchor," which pursues improved workability and thorough cost-effectiveness. We sincerely hope for your wide utilization of this product. 【Components】 ○ SP Bit ○ SP Bolt (Hollow rolled screw steel bar) ○ SP Coupler ○ SP Nut For more details, please contact us or download the catalog.
