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 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.

Manufactured from high-strength steel and designed to help prevent loose material from falling between the roof bolt pattern and provide strength to your immediate roof.
Options of each plate type are available in numerous dimensions to suit any bolt type and diameter in the Minova range. Plates are available with or without a hanger loop in black steel or hot dip galvanised.
Further developing our plate range, our 200 mm Crown plate is a cost-effective alternative to Combi plates, reducing the number of plates required and providing improved strata support.
In addition to a complete range of steel and chemical components, we can provide an extensive and complimentary range of accessories for steel strata support requirements.
Our range of accessories include:
• Strata Straps
• Mechanical Anchors
• Mine Nuts
• Pull Collars
Lokset capsules are filled with a reinforced thixotropic polyester resin in one compartment and a catalysed mastic filler in the other, separated by a physical barrier. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components causing a chemical reaction and transforming the resin mastic into a solid anchor.
