The bolt is made from high-tensile steel formed into a "C" shape (also known as a friction stabilizer).
When driven into a drill hole that has a smaller diameter than the bolt, the steel is compressed, creating radial friction against the rock walls.
This compression generates load transfer from the bolt to the surrounding rock, providing immediate support without the need for grouting or resin injection.

Friction bolts are primarily used in copper, gold or other metallic mines. They're cost-effective, reliable, and easy-to-install underground support solution, making them a preferred choice for mining operations requiring fast and efficient rock stabilization. Their proven performance in hard rock mines ensures safety and structural integrity in underground workings.
Made from high-yield, high-strength steel for superior durability.
Features a high-quality welded ring that maintains strong adhesion even under stress.
Even if the bolt body fractures, the welding ring remains securely in place, preventing sudden failures.
Available in black (uncoated) or hot-dip galvanized versions for enhanced corrosion resistance in harsh mining environments
1. Simple Installation
2. High Yield & Breaking Strength
3. Corrosion-Resistant Options
4. Strong Welding Ring Pull-Out Resistance
Friction bolt package is bundle, plate by pallet.
