Sinorock’s Friction Bolt improves rock stability and

safety factors by tightening as lateral strata movement

occurs. The Friction Bolt is primarily used in

metalliferous mining operations, but is also well suited

for rib support in coal operations. Sinorock’s

Friction Bolt is available in four sizes: 33 mm,

39 mm,42mmand 47 mm.

Strength and Versatility

Sinorock’s Friction Bolt is manufactured from highstrength steel.

For increased protection against corrosion, the Friction

Bolt is available in galvanized and stainless steel.

Installation Procedure:

1. Drill hole at proper diameter and depth. Diameter

is determined by on-site testing.

2. Insert Friction Bolt into the hole. A driving tool is

fitted into the rock drill’s chuck. Place Friction Bolt

and plate onto the installation tool.

3. Using percussion and thrust, fully drive the Friction

Bolt into the hole until the Dome Plate is tight

against the rock surface.
