Hexagon screw head bolts come in a large variety of sizes and diameters.Application:Bolts and nuts are designed with a hexagonal shape because it makes them easy to turn. With six sides, you can turn a fastener just one-sixth of the way to reach the next flat parallel. There are six flat parallels on hexagonal bolts and nuts.Others:A hex key wrench or Allen wrench has a hexagonal shaped body. The metal shaft may end in an L-shape or T-shape that serves as a handle.
