SDS Square Head Cable Bolt
Special Deformed Strand
Minova’s patented SDS Square Head Cable Bolts are designed to provide the same versatility as cable bolts while providing a higher degree of anchorage capacity. Added benefits of this cable bolt with its innovative square head indented strand design are improved resin/strand mechanical interlock, eliminated or reduced bulbs, lower hydraulic pressure during insertion and better encapsulation.
SDS Square Head Cable Bolts can be used in every application where traditional cable bolts are used and where standard ground support is marginal or inadequate. Common application areas include: gate roads, bleeder, recovery room, set-up room, intersections and other mine areas where additional support is indicated.
