1. Definition and classification of threaded rods
Threaded rods refer to rod-shaped parts with threads on the surface of the rod body, usually made of materials such as carbon steel, alloy steel, or stainless steel. According to the different thread shapes, threaded rods can be divided into the following common types:
1. Ordinary threaded rods. These rods have ordinary threads, which are usually used in low-requirement occasions, such as connecting components, manufacturing machinery, etc.
2. Semicircular threaded rods. These threaded rods have semicircular threads, which are usually used in more important engineering fields such as mines and bridges.
3. Rectangular threaded rods. These threaded rods have rectangular threads, which are usually used in engineering fields that require load-bearing, such as bridges and foundation piles.
