Sam Browne studs are a traditional method of making a closure on a book, folder, bag, box or other project. They are a small metal mushroom shaped stud with a screw at the base to fix the stud to a card or leather base.
Also known as a mushroom stud, this is a specialist binding and leather work fixing for a making a smart and simple closure.
A common way that Sam Browne studs are used is for card bound books or presentation folders, where the stud is screwed to the front cover through a punched or drilled 3-4mm hole. An elastic loop or tag can then come across from the back of the book or folder and slip over the stud to create the closing.
For leather work the stud is screwed to the leather then a slightly larger hole or a keyhole (small hole plus slit) can be punched in a strap that comes across (or an oversized back cover) and this will simply pop over the stud and complete the closing.
Traditionally Sam Browne studs were used for the belt studs on military uniforms.
