Type of Nuts:

Hex Nuts: A six-sided nut with internal threads that’s used with bolts or screws of matching diameter.

Lock Nuts: Designed to resist loosening due to vibration or torque, lock nut have features like nylon inserts, deformed threads, or serrated flanges to create friction and prevent unintended loosening.

Wing Nut: These nut have two “wings” that allow for easy hand tightening and loosening without the need for tools. They are often used in applications where frequent adjustments are necessary.

Square Nut: These nut have a square shape and are used with square bolts. They offer greater surface contact and can provide better resistance against rotation.

Flange Nut: This nut has a wide flange at one end that serves as a washer to distribute the load and prevent damage to the connected material.

Cage Nut: Designed to be inserted into square holes in equipment racks, these nuts provide a threaded hole for attaching components.

Jam Nut: A thinner nut often used as a companion to another nut to prevent loosening due to vibration.

Hex Coupling Nut: Used to connect two threaded rods or other fasteners, these long nut have internal threads along their entire length.

When selecting nuts, it’s important to ensure that they are compatible with the bolts or screws you’re using and that they meet the requirements of your application in terms of strength, corrosion resistance, and other factors.
