FAQ

What Are Nuts and What Are They Used For?

Nuts are fasteners with a hollow cylindrical shape and internal threads. They are combined with bolts, studs, or screws to attach objects securely. Nuts come in various forms, such as hex, flange, and lock nuts. They are commonly used in construction, machinery, automotive industries, and household applications. You create a strong and reliable connection by using nuts in conjunction with bolts.
 

What Types of Nuts Are There?

There are different types of nuts available for various applications:
 

• Hex Nut: These nuts have a hexagonal shape and are the most commonly used. They provide a good grip and can be easily tightened with a wrench.
• Jam Nut: Jam nuts are flat and used when a thin nut is required, such as in limited spaces. However, these nuts have limited load-bearing capacity.
• Lock Nut: Lock nuts have a special design that prevents the nut from coming off due to vibrations or shocks. They are often used in applications where secure fastening is required.
• Cap Nut: Cap nuts are used to cap a thread. They are often used when it's not intended for the thread to protrude through the nut (e.g., for safety reasons).
• Flange Nut: Flange nuts are fasteners with a wide, flat base (flange) that provides a larger surface area and greater stability when fastening materials. This results in a safe and reliable connection.
• Wing Nut: Wing nuts are specially designed nuts with wings on the sides, allowing them to be tightened by hand. This provides a quick and easy way to loosen and tighten without using tools.
• Castle Nut: These nuts have tilting properties. A pin can be inserted between these tilts through the thread. This prevents the nut from coming loose.
• Weld Nut: Nuts designed to be welded to a parent material. This is used to attach thin sheet metal parts with bolts or screws.
• Structural Nut: These nuts are intended for structural applications, according to EN1090, for high-strength preloaded fastenings. They should only be used with HV bolts and 2 HV washers as a set, all from the same manufacturer, according to the EN14399 standard.
• Coupling Nut: Longer nuts designed to connect two pieces of threaded rod.
• Knurled Nut: Nuts with a knurled edge on the outside. Like wing nuts, these nuts are designed to be tightened without using tools.
• Round Nut: Nuts with a saw cut on the end. A slotted screwdriver or a special slot nut screwdriver can tighten the nut. These nuts are often used in the electrical industry or machinery.
• Square Nut: Nuts with a square shape. These nuts are often used in a T-slot, rails, or connections where the material blocks the nut.
• Cage Nut: A nut with a housing made of spring steel. This is used, for example, to securely attach the nut in square holes in thin sheet metal.
• Trapezoidal Nut: Round nuts with internal trapezoidal threads. These are combined with external trapezoidal threaded products to adjust machine parts, for example.
   

Choosing the correct type of nut is essential based on the specific application and required properties, such as locking or space constraints. Nuts should be stronger than the bolts or screws for a safer connection. You can be assured of this when using nuts and bolts of the same strength class (e.g., an 8.8 bolt with an 8-class nut).
 

How Do I Choose the Right Nut Size?

Consider the corresponding bolt's diameter and thread when selecting the right nut size. Nuts and bolts should have the same thread size to fit together correctly. Accurate measurement and identification of the correct thread size are essential to ensure a secure connection. A caliper and thread pitch gauge are required to measure the external thread. For nuts, the wrench size indicates the thread diameter. It would be best to determine whether it's coarse or fine thread. Thread charts can help you make your selection.

What Is the Difference Between Metric and Non-Metric (Imperial) Nuts?

The difference between metric and imperial nuts lies in the unit of measurement.

Metric nuts are measured in nominal thread diameter (e.g., M4 for a 4mm nominal thread diameter) and millimeters per revolution (pitch). They are commonly used in European and international standards such as ISO and DIN.

Imperial nuts are measured in nominal thread diameter (inches) and threads per inch. They are primarily used in countries that use the imperial measurement system, such as the United States.
 

How Do I Prevent Nuts from Loosening?

You can take the following measures to prevent nuts from coming loose:
 

• Use the correct torque: Tighten the nuts securely using a torque wrench. This ensures good friction and prevents loosening due to vibrations.
• Use locking devices: For additional security, you can use locking devices such as thread-locking compounds, lock washers, or self-locking nuts. Depending on the choice, these can prevent the nut from unscrewing from the thread or even retain preload force.
• Inspection: Regularly check if the nuts are still securely tightened. If you notice a nut starting to come loose, tighten it immediately.
