Ball Combination Fastener Manufacturer Metric Threaded

Ball combination fastener is the fastener connected mainly with the ball in which the ball is move available, so the fastener can connect a big angle. Ball combination fastener mainly used in a place need to move around, such as toys, etc. Unified Coarse (UNC), commonly referred to as National Coarse (NC) in retailing. The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries. It has the same 60° profile as the ISO metric screw thread, but the characteristic dimensions of each UTS thread (outer diameter and pitch) were chosen as an inch fraction rather than a millimeter value. The UTS is currently controlled by ASME/ANSI in the United States. The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch. For diameters smaller than 1?4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given. Ever Hardware provides custom-made fasteners and customizable packaging.

Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion-resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc. This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part.
