Description
A star screw with a thorn washer that has a diameter of 1/4″ UNC approx: 6.35mm. It is therefore an American coarse threaded screw 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 screw has in 25, 4 mm. You measure the length under the skull and it is stated in millimeters. We have a lot of different makes in stock. It differs in color and surface treatment as well as how long the part of the bolt is threaded. It is a normal standard model of all screws we stock. We deliver what we have in stock at the moment.
Tip!
Note that you must measure the length of the screw under the skull, you measure the length in millimeters. You should not count on the screw head when measuring the length of the screw.
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"
