Product Description

Product Description

Black Oxide Hexagon Bolt

What is black oxide coating on bolts?
A chemical black finish is also referred to as black oxide or blackening. It is a 'conversion coating', which is a coating for metal where the surface of the part is subjected to a chemical or electrochemical process by the coating material, converting it into a decorative or protective substance.
 

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.
