Phoenix USA 1/4″-20 Nylock Nut (37018)

The Phoenix USA 1/4″-20 Nylock Nut (37018), recognized as a standard toolbox component, is a crucial fastener engineered to provide secure and vibration-resistant connections. This 1/4″-20 UNC (coarse thread) hex nut incorporates a nylon insert within its steel construction. This design creates a prevailing torque as it is tightened onto a mating bolt or screw, effectively locking the assembly and preventing unintentional loosening caused by movement or vibration. Commonly found in various repair, maintenance, and assembly applications, this nylock nut offers a dependable solution for ensuring long-lasting and stable connections.

KEY FEATURES AND BENEFITS:

• Secure Locking Mechanism: The integrated nylon insert firmly grips the threads of the mating fastener, providing a reliable locking action that resists loosening due to vibration and shock.
• Standard Thread Size: The 1/4″-20 UNC thread makes it compatible with a wide range of commonly used bolts and screws.
• Versatile Application: Suitable for use in automotive repairs, machinery assembly, household projects, and any application requiring a secure fastening solution.
• Ease of Use: Designed with a standard hexagonal shape, it can be easily installed and tightened using common wrenches or sockets.

SPECIFICATIONS:

• Thread Size: 1/4″-20 UNC (Coarse)
• Type: Nylock Nut (Nylon Insert Lock Nut)
• Material: Typically Steel (may vary with finish)
• Finish Options: May include Zinc Plated, Black Oxide, or Stainless Steel depending on the specific vendor.
• Wrench Size: Generally requires a 7/16″ wrench.
• Height/Thickness: Approximately 0.300″ to 0.328″ (varies slightly).
• Temperature Range: Nylon insert typically effective from -65°F to 250°F (-54°C to 121°C).

HOW TO USE:

• Select the Appropriate Bolt/Screw: Ensure the bolt or screw you are using has a 1/4″-20 UNC thread that matches the nylock nut.
• Position the Nylock Nut: Align the threaded opening of the nylock nut with the threads of the bolt or screw.
• Begin Threading: Start turning the nylock nut onto the bolt or screw by hand, ensuring the threads engage smoothly.
• Tighten with a Wrench: Once hand-tightened, use a 7/16″ wrench or socket to continue turning the nut. You will feel increased resistance as the nylon insert engages the threads.
• Achieve Desired Torque: Tighten the nut to the manufacturer’s recommended torque specification for your application to ensure a secure connection without over-tightening. The nylon insert will help maintain this tightness.

BENEFITS OF USING THE PHOENIX USA 1/4″-20 NYLOCK NUT (37018):

• Prevention of Loosening: Ensures integrity and safety of assembled components in environments subject to vibration, eliminating the need for frequent retightening.
• Durable Steel Construction: Offers reliable strength for various applications, while optional finishes like zinc plating enhance corrosion resistance.
• Versatile Compatibility: The standard 1/4″-20 thread ensures compatibility with a wide range of commonly used fasteners.
• Convenient Toolbox Component: Provides accessibility for repairs and assemblies, making it a practical addition to any toolkit.

FEATURES:

• Nylon Locking Ring: A durable nylon insert within the nut collar creates a frictional grip on the bolt threads.
• Hexagonal Head: Provides a standard six-sided grip for easy tightening and loosening with common tools.
• Prevailing Torque: The nylon insert generates a consistent resistance to rotation, preventing self-loosening.
• Thread Protection: The nylon insert can also offer a degree of protection against thread damage and corrosion.
• Reusability (Limited): While designed for secure locking, nylock nuts can often be reused, although the locking effectiveness may decrease with repeated use at higher temperatures.
