Product Description

Blackening Hexagon Bolt

What is the difference between blackening and black oxide?
Black Oxide, sometimes called blackening, is the act of converting the top layer of a ferrous material with a chemical treatment. Treating fasteners with a black oxide coating not only adds a nice clean black look but can also add a mild layer of corrosion and abrasion resistance.
 

Type:	Hexagon Bolt
Definition:	Hexagon Bolt, also called hex bolts or hex head cap screws, are threaded fasteners with a six-sided head. They are installed with a wrench or a socket. Compared to other fasteners, hex head cap screws provide a larger surface-bearing area for better clamping.
Description:	Hex bolts, also called hexagon screw head bolts, hex cap bolts, hex-cap screws, or machine bolts, are a very common choice when it comes to construction and repair. 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. This makes it easier to turn. Hex wrenches often come in a set with several different sizes.
