Grainger 1/4" UNC nut 1/4" UNC hex nut 1PY15

Grainger 1/4" UNC Nut 1PY15 – the inconspicuous but crucial connection

With the Grainger 1/4" UNC Nut 1PY15 you’re adding a classic hex nut to your project that does exactly what it’s supposed to do: hold reliably, clamp cleanly, and not be easily disturbed even after years of use. No frills, just a solid, precisely manufactured nut with a 1/4" UNC thread for right-hand threaded fastenings.

Precise 1/4" UNC thread for reliable connections

The core of this nut is the 1/4" UNC thread. It is a coarse, imperial Unified National Coarse thread that you’ll find wherever robust, repeatedly detachable connections are required. The right-hand thread design ensures that you can use it with standard tools and matching 1/4" UNC screws without having to think twice. Especially if you’re already working with other 1/4" UNC components, such as hex nuts, wing nuts, knurled nuts or self-locking variants, this model integrates seamlessly into your existing system.

Hex shape for easy tightening and loosening

The nut is designed as a hexagon, the classic hex design you know from workshops, mechanical engineering and everyday assembly work. Thanks to the six faces, you can grip it securely with an open-end wrench, ring spanner or socket. Even in tight installation spaces it can usually still be accessed quite well. We’d say: exactly the shape you expect when you say “normal” nut, just in clean Grainger quality.

18-8 stainless steel – durable, robust, suitable for everyday use

The Grainger 1/4" UNC Nut 1PY15 is made of 18-8 stainless steel. In everyday use this material is something like the standard for corrosion-resistant fasteners: resistant to moisture, many environmental conditions and typical application scenarios in the workshop, outdoor area or industrial environments. So if you don’t feel like dealing with flash rust, corroded threads or visually unattractive discoloration, this stainless-steel version is a safe choice.

Compatible with other 1/4" UNC nuts and designs

Things get interesting when you don’t just need a single nut, but are planning an entire set of 1/4" UNC connections. The Grainger 1PY15 is an excellent match for other 1/4" UNC nut types that you may already be using or want to add:

• 1/4" UNC hex nuts made of 18-8 stainless steel, ideal when you want to build multiple standard fastenings in the same quality.
• 1/4" UNC wing nuts made of 18-8 stainless steel, practical when you want to loosen or readjust connections without tools.
• 1/4" UNC hex nuts made of blackened steel, a good option when you deliberately want a different look or material, for example for indoor applications.
• 1/4" UNC hex nuts with nylon insert (self-locking, also 18-8 stainless), useful wherever nothing is allowed to loosen by itself due to vibrations.
• 1/4" UNC knurled nuts type 1 made of 18-8 stainless steel, with defined knurl height, base height, overall height as well as knurl and base diameter, when you need a grippy, hand-operable nut.

All these variants share the same 1/4" UNC right-hand thread type, allowing you to combine them flexibly depending on installation location, accessibility and desired handling.

Technical details at a glance

So you don’t have to search for long, here are the key data of the Grainger 1/4" UNC Nut 1PY15 in compact form:

• Nut type: hex
• Thread type: 1/4" UNC, right-hand thread
• Material: 18-8 stainless steel
• Field of application: ideal for screw connections with 1/4" UNC screws in workshops, mechanical engineering, assembly, DIY projects and many other applications

Who this hex nut is particularly interesting for

If you’re working in the imperial range, whether in mechanical engineering, on US equipment, in model building, with photo mounts or simply with older constructions that rely on 1/4" UNC, then this nut is a very obvious candidate. It is suitable for repairs as well as for new builds, for series assembly as well as for one-off pieces. And because it is made of 18-8 stainless steel, you can also use it wherever moisture, temperature fluctuations or changing conditions are the order of the day.

Practical application scenarios

Whether you’re retrofitting a bracket, overhauling a machine or screwing together a small frame: the 1/4" UNC hex nut 1PY15 integrates unobtrusively but effectively into your design. In combination with matching screws, wing nuts, knurled nuts or self-locking nuts you can build a system that is easy to operate both with tools and by hand. We’d say: one of those components you don’t have to think much about, because it just works.
