Tip!
Note that you must measure the length of the bolt under the skull, you measure the length in millimeters. You should not count on the bolt head when measuring the length of the bolt.
Check the picture how to measure.
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"
