The differences between fully threaded studs and bolts are as follows:

This is the fundamental difference between fully threaded studs and bolts. As shown in the first image, a Fully Threaded Stud has threads along its entire length, encased by threads, and is typically used with two nuts. A fully threaded Stud is a common component used to connect two or more parts, usually made of steel and shaped like a spiral. Unlike partially threaded studs, the entire length of a fully threaded stud is threaded, with hexagonal heads at both ends for easy tightening with a wrench or spanner. The advantages of fully threaded studs are:

1. Simple structure: Fully threaded studs have a simple structure, making them easy to manufacture and install, facilitating quick connections between components and improving work efficiency.

2. Easy installation: Fully threaded studs can be installed directly with a wrench or spanner without needing to coordinate with other parts, and no additional processing is required.

3. Cost-effective: Fully threaded studs are relatively low in cost, easy to purchase, and serve as economical connecting elements.

The second image depicts a Hexagon Head Bolt, featuring a hexagonal head and threads along its body. Hexagon head bolts, with their hexagonal structure, are more robust and durable during machining compared to other Screw types. Their unique structure grants them higher torque-bearing capacity, significantly reducing the risk of plastic deformation under torque, thereby extending their lifespan considerably.

Hexagon head bolts undergo surface oxidation treatment, endowing them with excellent wear resistance. In practical applications, due to their hexagonal design, hexagon head bolts snugly fit with nuts, enhancing their anti-seismic performance and effectively solving common loosening issues. Furthermore, disassembling hexagon head bolts is extremely convenient, requiring no specialized tools; only a hex key is needed to effortlessly remove the bolts. This design feature facilitates easy disassembly, saving time and labor costs.
