Grainger 1/4" UNC hex nut 1PY15

Versatile 1/4" UNC hex nut for photo accessories and fastenings

The Grainger 1/4" UNC nut 1PY15 is a versatile hex nut that is ideal for numerous assembly and fastening tasks. It is particularly interesting for photo and video applications, since the 1/4" UNC thread corresponds to the classic standard photo thread. You will find this thread on many tripods, cameras, quick-release plates, mounts, and other accessories. This makes this nut a practical solution if you want to expand existing setups, secure accessories, or implement custom mounting options.

Thanks to its special design, this nut combines the advantages of a classic hex nut with a more grippy shape that makes it easier to tighten and loosen by hand. At the same time, the flat sides provide sufficient contact surface for tools if you want to create a more secure connection. This gives you a well-thought-out combination of easy handling and reliable hold.

1/4"-20 UNC right-hand thread as a common photo standard

The nut has a 1/4"-20 UNC thread with right-hand thread and coarse pitch. This exact size is particularly widespread in the photo sector and is used for many mounting points for cameras and accessories. So if you are looking for a nut for compatible photo mounts, adapters, or tripod solutions, this model is a suitable choice. The nut can also be very useful for DIY projects in the studio, in rig setups, or for custom mounting solutions.

Thanks to precise manufacturing, the nut can be screwed cleanly onto matching threads. This makes assembly easier and ensures a secure, stable connection in everyday use.

18-8 stainless steel: robust, corrosion-resistant, and durable

Made from 18-8 stainless steel, the Grainger 1/4" UNC hex nut offers high resistance and a long service life. The material is robust, corrosion-resistant, and therefore very well suited for regular use. Especially in everyday photo work, with changing locations or in outdoor environments, it makes sense to rely on a durable stainless steel nut that works reliably even with frequent use.

The simple, untreated surface underscores the functional character and makes the nut a solid fastening element for many applications. Thanks to the combination of stainless steel material and proven thread form, it is suitable both for professional use and for ambitious hobby users.

Dimensions and technical specifications at a glance

With its compact dimensions, the nut can be easily integrated into existing constructions. The hex shape ensures good tool engagement, while the design also makes it easier to tighten by hand. This makes the nut suitable both for classic screw connections and for applications where quick assembly and disassembly are important.
