Grainger 1/4" UNC hex nut 3PDG5, self-locking with nylon insert - 1/4" UNC hex nut, self-locking

Reliable 1/4" UNC hex nut with locking insert

The Grainger 1/4" UNC hex nut 3PDG5 with nylon insert is the right choice when you want to create bolted joints that are secure and resistant to vibration. Unlike a standard hex nut, this model features an integrated nylon insert that additionally secures the thread. This makes the nut particularly suitable for applications where shocks or movement could cause a connection to loosen unintentionally. That is precisely why this self-locking nut is a practical solution for many technical, craft, and also photographic applications.

The 1/4" UNC thread is particularly interesting because it corresponds to the common standard photo thread. This size is used on many tripods, mounts, quick-release plates, camera accessories, and adapter solutions. So if you are looking for a durable nut with protection against loosening for photo accessories or other fastening solutions, this version is an excellent choice.

Additional locking by nylon ring

The integrated nylon insert ensures that the nut engages positively with the external thread when screwed on. This creates additional friction, which makes it significantly more difficult for the nut to loosen prematurely due to vibrations or recurring movements. This is exactly what makes self-locking nuts with nylon inserts so popular when a connection needs to remain reliably secure over the long term.

The nut is reusable and is therefore also interesting for applications where components need to be loosened and reassembled as required. At the same time, you should note that this design is not intended for high temperatures, as the nylon insert is not heat-resistant. However, for many standard applications indoors, in workshops, or for accessory installations, it is a proven and practical solution.

Robust design made of Grade 8 steel

Manufactured from Grade 8 high-strength steel, the Grainger 3PDG5 hex nut provides a robust and durable basis for secure bolted joints. The nut is suitable for many general assembly tasks as well as for special applications where a strong and long-lasting connection is required.

Thanks to the standard hex shape, you can easily install the nut using common tools. At the same time, it remains compact enough to be integrated into existing constructions or accessory solutions.
