Fine Pitch Dome Nuts.

What are Fine Pitch Dome Nuts?

Fine pitch dome nuts are precision nuts featuring a domed cap, hexagonal body and a fine metric thread, designed to provide threaded assemblies a secure and aesthetically pleasing finish. 

The domed cap safeguards exposed threads and prevents damage or injury from protruding bolt ends. The fine pitch threading offers enhanced strength and precision, making these nuts suitable for applications requiring high tensile and shear strength.

How Fine Pitch Dome Nuts Work

Fine pitch dome nuts function by threading onto bolts or studs with matching fine pitch threads. The increased number of threads allows for greater thread engagement, resulting in improved load distribution and resistance to loosening under vibration.

The domed cap not only protects the threads but also contributes to a neat and finished appearance, making these nuts ideal for applications where both functionality and aesthetics are important.

Materials Fine Pitch Dome Nuts Are Made From

Accu’s fine pitch dome nuts are available in two main material options: A2 Stainless Steel and A4 Marine Grade Stainless Steel.

A2 Stainless Steel provides reliable corrosion resistance, making it well-suited for general-purpose use in a variety of indoor and outdoor environments. For more demanding conditions, A4 Marine Grade Stainless Steel offers superior corrosion resistance, particularly in marine and other harsh or chemically exposed settings. This makes A4 an excellent choice for applications requiring long-term durability in aggressive environments.

Sizes and Types of Fine Pitch Dome Nuts Available

Our range of fine pitch dome nuts is available in metric sizes ranging from M8 to M24, with various fine and extra fine thread pitches to accommodate different application requirements. While we recognise that within the metric standards, there are no additional naming conventions for the varying pitch sizes, we at Accu believe that using fine and extra fine terminology allows for an easier way to find the right product you need.

FAQs

Q: What is the difference between fine pitch and coarse pitch threads?

A: Fine pitch threads have a smaller distance between threads, resulting in more threads per unit length. This allows for greater thread engagement, improved strength and better resistance to vibration compared to coarse pitch threads.

Q: When should I use fine pitch dome nuts?

A: Fine pitch dome nuts are ideal for applications requiring high strength, precision, and vibration resistance. They are commonly used in automotive, aerospace and machinery assemblies where these characteristics are critical.

Q: Are fine pitch dome nuts compatible with standard bolts?

A: Fine pitch dome nuts must be used with bolts or studs that have matching fine pitch threads. Using them with coarse pitch bolts leads to cross-threading and is incompatible.
