Rock bolts are commonly used in civil engineering and mining to reinforce and stabilize rock masses. A rod or bar is inserted into a drilled hole, which is then grouted in place using cement or resin. FRP Rock bolts withstand tensile forces and evenly distribute load, eventually increasing overall strength. They control rock movements, reduce deformation and prevent collapses.

Washers might look like simple discs, but they serve important purposes. They distribute the weight of a bolt or screw, preventing damage to the surface underneath. Picture this: if you were to sit on a balloon, it would pop. But if you sat on a board that was resting on the balloon, it could hold your weight. That's what washers do they protect and support!
