How Split Set® Rock Bolts and Friction Bolts Work
Split Sets are rock bolts with only 2 parts, a tube and matching domed bearing plate. The high strength steel
tube is slotted along its length. One end is tapered for easy insertion into a drill hole and the other has a
welded ring flange to hold the bearing plate. With the bearing plate in place, the tube is driven into a slightly
smaller hole, using the same standard percussion drill that made the hole. As the tube of the rock bolt slides
into place, the full length of the slot narrows, causing radial pressure to be exerted against the rock over its
full contact length.
Split Set® rock bolts give you a choice of tube and plate sizes.
In the hole, the tube exerts radial pressure against the rock over its full contact length, and also provides immediate plate load support.
Quality Standards
Split Set® rock bolts (friction bolts) are manufactured to a highest standard of quality. Rigid standards of quality are achieved by exhaustive quality control, testing and inspection procedures. Detailed drawings specify materials, dimensions, and tolerances. Every Split Set® is identified with model number, length, factory, rolling date, and heat lot of the steel.
Installation
Fast, easy installation of our friction rock bolts reduces bolting costs. Rock bolts can be installed quickly, usually in less than a minute, using a jack drill, a stoper, a roof-bolting jumbo, or any other type of drill. Installation can be done in a few easy steps:
For more information, please visit our website.
- Drill the hole.
- Replace the drill steel with a driver tool.
- Slide the plate on the tube.
- Drive the tube in with the drill / drifter
Rock Bolt Pull Tests Prove Sustained Grip
Pull tests help verify the effectiveness of the stabilizers upon installation and over periods of time. Pull collars may be used on selected tubes for later testing.
Utility Hangers
Split Set® utility hangers are available in 18 and 24 inch (46 and 61cm) lengths. They are used to support cables, ductwork, pipes, trolley wires, etc. They are not, however, for ground support, but they offer the same installation advantages as Split Set® stabilizers. Lightweight items such as ventilation tubing may be hung from the loop on the bearing plate.
Easiest Way to Install Screen & Mesh
Split Set® utility hangers can make screen and mesh installation much easier, faster, and safer. After your opening is secured with Split Set® stabilizers, install the mesh all at once by driving Split Set® utility hangers inside the stabilizer tubes.
No new holes are needed. There's no awkward handling of mesh at the end of a long bolt, or under unsupported ground. The mesh screen conforms to the rock tightly. No other rock bolt has these advantages.

Nuts and bolts work together with washers to connect work pieces. You may hear the terms nuts and bolts used interchangeably, but a bolt has a very different function than a nut. We&#;ll discuss different types of each piece of hardware, when you&#;d use them and the basics of how each piece functions to join pieces together.
Goto TRM to know more.
Bolts have a head with a driving surface (typically hexagonal, to fit a wrench or socket/ratchet combination) and a cylindrical shaft that runs through the work pieces you&#;re assembling. The shaft is threaded but often has an unthreaded portion known as the shank or body near the head. The shank reduces the likelihood of the bolt shearing or snapping as the stronger, unthreaded portion carries most of the load. This unthreaded portion can also make it easier and faster to install longer bolts.
In most assemblies, you&#;ll need a washer &#; a thin, unthreaded piece that fits onto the bolt shaft. Its function is to spread the load of the connection over a greater area or to help prevent the fastener from loosening once installed.
A nut pulls the work pieces together along the bolt shaft. A nut is threaded like a bolt, but while a bolt has external threads along the shaft, a nut has internal threads. The nut threads fit the threads on the bolt, allowing the nut to spin along the bolt shaft. A nut designed to work with a bolt will have a driving surface like that of the bolt (a hexagonal nut works with a hex-head bolt).
One typical application for a bolt, washer and nut is to insert a bolt into matching holes on work pieces you&#;re fastening and then tighten the nut. As you tighten the nut, it cinches the pieces together, forcing the washer against one element and pulling the bolt head tightly against the other element. You&#;ll often need two wrenches so you can hold the bolt head in place while tightening the nut.
