Custom Nuts

What Are Custom Nuts?

Custom nuts are modified or fully bespoke fasteners designed to match the technical, spatial or environmental requirements of specialized applications. These modifications may include specialized threads, unusual dimensions, notches, bevels or integrated locking features.

Customization ensures optimal fit and performance in applications where off-the-shelf nuts cannot meet operational demands. Nickel Systems can machine, modify or finish nut products to your exact blueprint using exotic alloys suited for extreme heat, pressure or corrosive exposure.

Types of Custom Nuts

Nickel Systems produces a diverse range of custom nuts suited for specialized uses:

• Impeller nuts: These nuts secure impellers onto rotating shafts in pumps and compressors. They resist vibration and mechanical fatigue under constant motion.
• Coupling nuts: These are elongated, internally threaded nuts for joining threaded rods or studs. They are ideal for applications that need precise alignment or extended reach.
• Flange nuts: Flange nuts are a type of hex nut with an integrated flange that distributes load over a wider surface, providing enhanced holding power and reducing the need for separate washers.
• Slotted nuts: These fasteners feature slots to accommodate cotter or split pins for mechanical locking. They are frequently used in automotive and aerospace assemblies.
• Square nuts: Square nuts are four-sided components that provide greater resistance to loosening and are ideal in applications requiring increased grip.
• Wheel nuts: Also known as lug nuts, these fasteners securely fasten wheels to vehicles, ensuring safety under dynamic loading.
• Lock nuts: These nuts provide a secure hold under vibration, stress or thermal cycling conditions. Options include deformed thread, nylon-insert or 12-point configurations for added grip.

Considerations for Purchasing Custom Nuts

When specifying custom nuts, consider the following:

• Material selection: Match material properties to environmental and mechanical requirements.
• Dimensional accuracy: Confirm the thread size, pitch and nut dimensions your assembly requires.
• Locking features: Determine if integrated locking mechanisms are necessary for vibration-prone applications.
• Surface finish: Specify coatings or treatments for corrosion resistance and wear protection.
• Custom requirements: Communicate any unique design elements or compliance needs during the inquiry.
• Geometry: When choosing between hex, flange, square or slotted designs, consider space constraints, required torque and load distribution.
