Friction Bolt-33mm-manufacture,factory,supplier from China

33mm Friction Bolt Functions33mm Friction Bolt  is a frictional ground support system.

Friction Bolt-47-1800mm FunctionsFriction Bolt-47-1800mm Friction bolt is a frictional ground support system.

Friction Stabilizer BoltFriction Stabilizer Bolt is a frictional ground support system.

Friction Bolt-47-2400mm FunctionsFriction Bolt-47-2400mm is a frictional ground support system.

Friction Bolt-33-1500mm FunctionsThe Friction Bolt-33-1500mm operates as a ground support system through frictional forces. When the bolt is inserted into a drilled hole with a smaller diameter, the slot compresses, reducing the bolt's diameter.
