Standard Hex Nuts
We stock a wide range of high-quality hex nuts designed to meet the diverse needs of various industries. Manufactured from A2 and A4 stainless steel, our hex nuts offer excellent corrosion resistance and are ideal for demanding environments. These hex nuts are available in sizes from M2 to M56.
Explore our range of Standard Hex Nuts:
- Full Hex Nuts (DIN 934): Our standard hex nuts provide a secure and reliable fastening solution for a wide range of applications.
- Half Hex Nuts (DIN 439): Ideal for applications where space is limited, half hex nuts offer a lower profile while maintaining a secure grip.
- Studding Connector Nuts (DIN 6334): Designed to securely connect two threaded rods or studs, these nuts are essential for many construction and engineering applications.
- Spherical Seating Hex Nuts (DIN 6330): Featuring a spherical seating surface, these nuts compensate for minor misalignment between mating surfaces and help ensure a secure fit.
Choosing between Full and Half Hex Nuts:
- Use Full Hex Nuts where space is not restricted and a larger bearing surface is required.
- Choose Half Hex Nuts when clearance is limited. Half hex nuts can also be used as jam nuts where two nuts are tightened together to lock the assembly in place.
Stainless Steel Properties:
- Corrosion resistance: Suitable for marine, outdoor and food processing environments.
- High strength: Provides long-term durability and dependable performance.

Frequently Asked Questions
Why is it called a hex nut?
The name hex nut is short for hexagonal nut, so hex nuts are named after their hexagonal, six sided shape. This is probably the typical nut that most people visualise when you talk about a fastening nut. The hex nut has become one of the most commonly used nuts in the UK market. You'll see it being used in applications across the construction, engineering and automotive industries, and in many DIY projects. Its hexagonal design makes hexagonal nuts easy to grip with wrenches and pliers, streamlining the tightening and loosening processes. The hex nut's shape sets it apart from other popular nuts such as wing nuts and square nuts.
What types of hex nuts are there?
We sell standard hex nuts in two styles, a half hex nut and a full hex nut. Both are available in different stainless steel grades, providing options for A2 hex nuts and A4 hex nuts. The main difference between a stainless full hex nut and a stainless half hex nut is seen in their respective heights and usages. The full hex nut is the standard hex nut that is used for general fastening of bolts, screws, threaded rods and other components. The half hex nut is a thinner version of this, with a reduced height, it can be referred to as a jam nut or simply a thin nut. Its reduced height makes it a good choice for applications with limited space or very short threads, where a full size hex nut would not fit. Additionally, they are often used as a secondary nut, alongside a full hex nut. In this role the half hex nut acts as a locking nut and helps to prevent the primary full hex nut from loosening. This could be useful in applications where the fastened object is subjected to regular vibrations. Similarly, another popular anti-loosening strategy is to jam two half hex nuts next to each other and then tighten them into each other. Hence the name jam nut - thanks to the reduced height of the half hex nuts, using two won't take much more space than using one full hex nut.
Do you only sell stainless steel hex nuts?
Our range of metal hex nuts is focused around stainless steel hex nuts. This is because of the high quality and premium finish of these products, which makes them a reliable and long lasting fastening solution with grades of stainless that can perform well even in harsh marine or industrial environments. Despite not being listed, we can also provide titanium hex nuts where necessary. This is a high grade material that is usually reserved for specialist applications that need to capitalise on the excellent strength to weight ratio, low weight and exceptional corrosion resistance that titanium offers. The aerospace and performance automotive industry provide two good examples of this.
Why are your hex nuts made from stainless steel?
The main advantage of using stainless steel for a hex nut is the resulting strength and durability of the product. Stainless steel hex nuts are able to withstand high pressures and temperatures over long periods of time without breaking. This makes them well suited for use in heavy machinery, heavy load applications or in punishing environments where other metals would degrade. Their resistance to rust and corrosion adds to the long lifespan of the product. In fact, A4 hex nuts can be used in coastal environments or on boats and function well despite regular contact with salt water. Stainless steel hexagonal nuts are also simple to maintain, and their shiny and smooth appearance adds a nice finishing aesthetic to any application. In summary, stainless steel hex nuts are a dependable fastening solution that can be relied upon to perform well over long periods of time, in almost any application.
What is the difference between a nut and a hex nut?
A nut is a general term used to describe a fastener with a threaded hole that is usually used to secure a bolt, threaded rod or other threaded components together. In comparison, a hex nut describes a particular style of nut, which has six sides and is hexagonal in shape. A hex nut is one of the most commonly used nuts in the UK market across many industries and many people visualise this style of nut when they think of a nut. Some other commonly used styles of nuts that we sell include domed nuts, cage nuts, t nuts and shear nuts.
