Bolt structure refers to the way in which a bolt is designed and constructed. Bolts are commonly used in various industries such as construction, automotive, and manufacturing to join two or more pieces of material together. The structure of a bolt plays a crucial role in determining its strength, durability, and performance.

The fundamental principle behind the operation of a plastic expansion bolt lies in its unique design. It consists of a threaded shaft, a plastic sleeve, and a nut. When the bolt is inserted into a pre-drilled hole, the plastic sleeve expands as the bolt is tightened. This expansion creates friction against the inner wall of the hole, providing a strong grip and anchoring the bolt firmly in place.
