Stainless steel 304 hex bolts are a popular choice for various applications due to their excellent corrosion resistance and durability:

1. Fully Threaded Hex Bolt: This type of bolt has threads that run the entire length of the shank, providing maximum grip and strength.

2. Partially Threaded Hex Bolt: These bolts have a threaded portion at the end, while the remaining portion is unthreaded. They are often used in applications where a specific amount of thread engagement is required.

3. Tap Bolt: Tap bolts, also known as fully threaded hex cap screws, have a hexagonal head and are fully threaded. They are commonly used in machinery and construction applications.

4. Hex Flange Bolt: These bolts have an integral washer-like flange under the head, which distributes the load and provides a larger bearing surface. They are often used in automotive and industrial applications.

5. Hex Head Shoulder Bolt: Shoulder bolts have a cylindrical shoulder between the head and the threaded portion. They are commonly used in applications where precise spacing or alignment is required.

6. Hex Lag Bolt: Lag bolts, also known as lag screws, have a hexagonal head and coarse threads. They are primarily used for securing heavy materials to wood, such as framing or attaching hardware.
