Industrial Nuts
Nuts are internally threaded specialty fasteners that work in conjunction with matching bolts. The primary purpose of a nut and bolt combination is to secure a joint from vibration, as vibration can lead to loosening. Hardware nuts are most commonly used for industrial machine assembly.

A Guide to Different Types of Fastener Nuts
Fastener nuts are essential components in a wide variety of mechanical, construction, and automotive applications. They are designed to pair with bolts, screws, and other fasteners to create secure, lasting connections between parts. There are many types of fastener nuts available, each tailored for specific uses. Understanding the different types can help you select the right nut for your project.
1. Finished Nuts
Finished nuts are the most common type of nut. They are fully processed to meet specific industry standards, with clean, sharp threads and smooth surfaces. These nuts come in various sizes, materials, and strengths, offering a reliable solution for general-purpose fastening.
2. Stainless Nuts
Stainless steel nuts are resistant to corrosion and rust, making them ideal for use in harsh environments. Stainless nuts are commonly used in outdoor or marine applications where the nut is exposed to moisture and environmental factors that could cause other materials to degrade.
3. Acorn Nuts
Acorn nuts are also known as cap nuts. They have a rounded, dome-shaped top that covers the exposed end of a bolt, offering a clean, aesthetic finish while preventing injuries from sharp threads. These nuts are commonly used in automotive and furniture applications where appearance matters.
4. Lock Nuts
Lock nuts are designed to prevent loosening under vibration or torque. They come in various forms, such as nylon insert lock nuts and all-metal lock nuts. The nylon insert creates friction, keeping the nut secure, while all-metal lock nuts rely on deformation to maintain a tight fit.
5. Axle Spindle Nuts
Axle spindle nuts are designed for use in automotive and machinery applications where they secure axles, spindles, and other critical rotating components. These nuts often feature a special design to withstand high levels of torque and prevent loosening.
6. Jam Nuts
Jam nuts are thinner than standard nuts and are typically used in conjunction with a regular nut to prevent loosening. They are often used in mechanical and automotive settings to secure parts when space is limited or when a thin profile is needed.
7. Machine Screw Nuts
Machine screw nuts are designed to work with machine screws, providing a secure and tight fit. These nuts are available in various materials, such as steel, stainless steel, and brass, and are used in precision machinery, electrical components, and electronics.
8. Flange Nuts
Flange nuts have a wide, integrated flange that provides a larger surface area to distribute the load and prevent the nut from digging into the material. They are commonly used in automotive and industrial applications where vibration resistance and load distribution are important.
9. Collar Nuts
Collar nuts are similar to regular nuts but have a collar that helps prevent them from loosening. They provide extra support and are commonly used in automotive or machinery applications to secure components with precision.
10. Castle Nuts
Castle nuts are designed with a rounded, castellated shape. They are often used with a cotter pin to prevent them from loosening. Common in automotive and heavy-duty machinery applications, castle nuts are essential when secure fastening and locking are required.
11. Nylon Insert Nuts
Nylon insert nuts feature a nylon ring inside the nut that provides resistance to vibration and prevents the nut from loosening. This design is often used in applications that require strong, reliable fastening, such as in the automotive industry or machinery.
12. Slotted Nuts
Slotted nuts have slots that allow for easy adjustment and fastening. These slots can be used with a pin or a wire to secure the nut in place, making them ideal for applications that need to be adjusted or replaced frequently, such as in machinery.
13. Speed Nut
Speed nuts are a quick and efficient fastening solution that can be installed without tools. These nuts are often used in sheet metal applications or where quick assembly and disassembly are required.
14. Square Nuts
Square nuts have four sides instead of the typical six, providing greater surface area for increased grip. They are often used in applications where high levels of torque or vibration are involved, such as in heavy machinery or construction projects.
15. Hex Coupling Nut
Hex coupling nuts are long, cylindrical nuts that connect two male-threaded fasteners. They are typically used in applications where longer threads are needed, such as in the construction of pipe assemblies or for connecting rods.
16. Structural Nuts
Structural nuts are heavy-duty nuts designed to hold structural components together in building or construction projects. They often feature thicker walls and stronger materials to handle high loads and stresses.
17. Tee Nuts
Tee nuts are embedded into wood or metal surfaces to provide a secure threading point for bolts or screws. They are often used in woodworking projects or furniture assembly where a strong, durable fastening solution is needed.
18. Weld Nuts
Weld nuts are nuts designed with a flange that allows them to be welded directly onto a metal surface. These nuts are commonly used in applications where a strong, permanent fastening point is needed, such as in automotive or industrial settings.
19. Wing Nuts
Wing nuts feature two "wings" on either side, allowing them to be tightened or loosened by hand without the need for tools. They are typically used in applications that require frequent adjustments or removals, such as in electrical or assembly work.
Each type of fastener nut plays a specific role in ensuring the stability, strength, and functionality of various projects. From finished nuts for general purposes to specialized nuts like wing nuts, lock nuts, and weld nuts, the right choice of nut ensures the safety and durability of your construction or mechanical project. Whether you are working in automotive, construction, or DIY applications, understanding the different types of fastener nuts will help you make the best decision for your needs.
