The Secura Bolt is a solid reinforcing bar for use in strata environments of underground mines. Design includes a unique paddle system to improve resin mixing and resin film shredding. Consistent and efficient mixing of resin capsule components provide higher bond strength in large diameter boreholes
The solid reinforcing bar is threaded at one end with a high strength R thread profile, including a modified rope thread with large root and small crest areas. A torque nut is attached at this end. Available in various lengths and can be supplied black or hot dip galvanised.
We can supply a comprehensive range of plates for use with the Secura bolt. Plates most typically used with Secura bolts are:
We can supply a range of drivers for use with hand-held or mechanised bolting equipment.
LOKSET® RESIN CAPSULES
The Lokset resin system provides rapid anchoring of the bolt to the surrounding strata. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components transforming the resin mastic into a solid anchor.
