Bolt Manufacturers High Strength Fasteners Supplier Customizable

One of the most famous bolt manufacturers-Ever Hardware Industrial Limited is located in the world’s manufacturer center-Dongguan, China. A bolt is a form of threaded fastener with a 1.0/1.25/1.5 pitch external male thread. Bolts are thus closely related to, and often confused with, screws. The distinction between a bolt and a screw is unclear and commonly misunderstood. There are several practical differences, but most have some degree of overlap between bolts and screws. Ever Hardware provides custom-made fasteners and customizable packaging.

The defining distinction, per Machinery’s Handbook, is in their intended purpose: Bolts are for the assembly of two unthreaded components, with the aid of a nut. Screws in contrast are used with components, at least one of which contains its own internal thread, which even may be formed by the installation of the screw itself. Many threaded fasteners can be described as either screws or bolts, depending on how they are used.

Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper-based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimize light reflection. To achieve maximum corrosion resistance the black oxide must be impregnated with oil or wax. One of its advantages over other coatings is its minimal buildup.
