The machine fasteners are a threaded separator of defined length used to raise one assembly above another. They are usually round or hex (for wrench tightening), often made of aluminum, brass, or nylon, and come in male-female or female-female forms. In electronics, they are frequently used to raise a printed-circuit board above a surface. Insulating standoffs keep two parts from touching each other, thereby preventing electrical shorts. When used to fasten cable connectors (i.e. “D” connectors) together, they are called “jack screws”. In contrast, a spacer is an unthreaded piece of tubing that lets the entire bolt pass through. Since they cannot be tightened, they are usually round. Ever Hardware provides custom-made machine fasteners and customizable packaging.
Type 304 or A2, with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels. Its alloys are all modifications of the 18% chromium, 8% nickel austenitic alloy. Type 304 proves to be resistant to oxidation, corrosion, and durability. All provide ease of fabrication and cleaning, prevention of product contamination offers a variety of finishes and appearances. Type 304 stainless steels are used in corrosion-resistant electrical enclosures, auto molding and trim, wheel covers, kitchen equipment, hose clamps, exhaust manifolds, stainless hardware, storage tanks, pressure vessels, and piping.
Type 316 or A4 stainless steel is an austenitic chromium-nickel stainless and heat-resisting steel with superior corrosion resistance as compared to other chromium-nickel steels when exposed to many types of chemical corrodents such as seawater, brine solutions, and the like. Since Type 316 stainless steel alloy contains molybdenum bearing it has a greater resistance to chemical attack than 304. Type 316 is durable, easy-to-fabricate, clean, weld, and finish. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides, and fatty acids at high temperatures.
