Description
The nut fits a standard bolt that has a diameter of 1/4″ UNC approx: 6.35mm. It is therefore an American coarse threaded bolt that has an outer diameter of 6.35mm, which is then called 1/4″ It has 20 threads in one inch = 25.4mm, if you are unsure you can count the number of threads the bolt has in 25, 4 mm.
Tip!
The difference between UNC and UNF is the number of threads per inch.
UNF is fine-threaded with more threads per inch than the coarse-threaded UNC thread.
The smaller sizes are divided from 0 to 12 and are called numerical threads. We call them "Screws"
The larger sizes start with 1/4″ and so on. We call them "Bultar"
