Pin nailers and staplers

 

— pins and studs are called fasteners in the form of thin rods. The key difference from nails is the lack of a head; in addition, the pins can be clogged as a whole (up to the possibility of hiding the fasteners under a layer of paint), and partially, so that part of the part protrudes above the material. There are other specific features — for example, a hairpin may have a thread in the upper part.
