Expansion bolts

Expansion bolts, also known as expansion screws or expansion plug bolts, are a widely used fastener, especially suitable for fixing various equipment, brackets or pipelines on hard materials such as concrete, brick walls, rocks, etc. Its working principle is to generate an expansion force in the expansion pipe through the wedge-shaped slope of the bolt, so that a strong friction force is formed between the expansion pipe and the inner wall of the drilled hole, so as to firmly fix the bolt.
