What different thread designs are available with the Flange Bolt depending on my needs?

Oct 11,2023

Flange bolts are available with different thread designs to accommodate various needs and applications. The choice of thread design depends on factors such as the type of material being fastened, the level of load distribution required, and the environment in which the fastener will be used. Here are some common thread designs available with flange bolts:

Unified Thread (UN or UNC):

Unified threads are standard thread designs commonly used in North America. UN threads are for screws and bolts, while UNC threads are for nuts. These threads have a 60-degree thread angle and come in various sizes and pitches.

Metric Thread (ISO or DIN):

Metric threads are standard thread designs used in many parts of the world, especially in Europe and Asia. They follow ISO or DIN standards and have a 60-degree thread angle. Metric flange bolts are available in a wide range of sizes and pitches.

Fine Thread:

Fine threads have a smaller pitch than standard threads of the same size. They are used in applications where higher clamping forces or finer adjustments are required. Fine-threaded flange bolts are suitable for specific applications where precision is essential.

Coarse Thread:

Coarse threads have a larger pitch than standard threads of the same size. They are commonly used in applications where rapid assembly or disassembly is required. Coarse-threaded flange bolts are often used in construction and automotive applications.

Threaded Stud:

Some flange bolts have a threaded stud on one end and a flange on the other end. These threaded studs are often used in conjunction with nuts to create a secure fastening.

Left-Hand Thread:

Left-hand threads turn counterclockwise to tighten, as opposed to the standard right-hand threads that turn clockwise to tighten. Left-hand threaded flange bolts are used in specific applications where reverse threading is necessary.

Acme Thread:

Acme threads have a trapezoidal profile and are commonly used in applications where high load capacity and efficient power transmission are required. Acme-threaded flange bolts are used in machinery and mechanical systems.

Unified Thread with Locking Feature:

Some flange bolts come with unified threads that incorporate a locking feature, such as a nylon insert or metal insert lock nut. These locking features help prevent the bolt from loosening due to vibration.

Specialized Threads:

In some cases, flange bolts may have specialized thread designs tailored to specific applications. These threads may have unique profiles or characteristics to meet specific engineering requirements.
