high quality China brass flat rivet

Machine screw / flat rivet : is designed to hold pieces of machinery together. Most machine screw require that the hole already be drilled and threaded, although there are a few types of machine screw capable of tapping their own holes. Like other screw, machine screw are available in a variety of shapes and sizes. Pan head machine screw are machine screws with heads that are flat on top and rounded on the sides. They're similar to oval head machine screw, which also have rounded sides; the difference is that oval head screws have a rounded top, too, as opposed to a flat top, and they have tapered bases. Both are commonly used for metal applications. Pan head machine screw can also be differentiated from flat head machine screw, which have flat tops, as well. However, flat head machine screw are tapered on the underside of the head so they can lie flush with the material they're driven into. Meanwhile, round head machine screw have flat bottoms with rounded heads, much like half a sphere. Round head machine screw can't sit flush with the material they're driven into; instead, their heads poke out like little bumps.
