B7 Heavy Hex Bolt Teflon Xylan 1070 Blue is a type of high-performance fastener that combines the strength of a hex bolt with the non-stick properties of Teflon. It is typically made of carbon steel or stainless steel and has a threaded hexagon-shaped body that can be engaged with a corresponding nut or other threaded fastener for secure fastening. The surface of the bolt is then covered with a Teflon coating to provide a slick, non-stick surface that resists galling and corrosion. The B7 Heavy Hex Bolt Teflon Xylan 1070 Blue is commonly used in high-performance applications where maximum tensile strength and non-stick properties are required, such as in the oil and gas industry, chemical processing plants, and other industrial settings.
