Incoloy 800 fasteners resist oxidation at high temperatures, a problem with most stainless steel alloys. Fasteners made from Incoloy 800 are also in great demand in petrochemical and chemical processing. Even when exposed to very high temperatures, Incoloy 800H fasteners maintain a very stable structure, making them very practical and sought after in many industries.

Hastealloy is a term that refers to a group of corrosion resistant metal mixtures that are based on nickel. Hastealloys have a unique combination of properties that provide them with significantly stronger corrosion resistance capabilities compared to traditional alloys. As such, it was widely accepted in the chemical process and associated industries, and now has a 50-year-old track record of proven performance in a vast number of corrosive chemicals.

Alloy 20 washers provide good performance in hot sulfuric acid, specifically they offer good resistance to stress-corrosion cracking in boiling sulfuric acid at specific range of 20% to 40% concentration, as well as general sulfuric acid resistance. Alloy 20 offers solid acid protection and will perform better than Duplex or even Monel, but for high temperature and high concentration acids, you may need to look to Inconel or Hastelloy fasteners. In addition, Alloy 20 washers also show useful resistance to phosphoric acid and nitric acid.

Fasteners have excellent resistance to pitting and crevice cracking. In addition, we offer fasteners with excellent resistance to water corrosion, general corrosion and chloride stress corrosion cracking.

The results reveal that Inconel 625 is excellent in resist the corrosion attack in seawater. However, at increasing temperature, the corrosion resistance of this metal decrease.

Gold 926 fasteners are also similar in composition to 904L, but with the addition of nitrogen and molybdenum, resulting in alloy 926 bolts with improved general corrosion resistance as well as pitting and crevice corrosion resistance. Because Alloy 926 is resistant to chloride stress corrosion cracking, it makes 926 fasteners ideal for desalination, pulp and paper mills. This alloy is also ideal for dilute sulfuric and phosphoric acid applications.

Its outstanding strength and toughness in temperature ranges from cryogenic temperatures to high temperature up to 2000¡ã F (1093¡ã C) are derived primarily from the solid solution effects of the refractory metals Columbium and molybdenum in a nickel-chromium matrix.

Alloy 20 Heavy Hex Nuts, also referred to as structural nuts, are both thicker and wider than a standard (finished) hex nut and compatible with high strength and large diameter bolts. Nuts in sizes 7/16″ and smaller are double chamfered. Nuts larger than 7/16″ are either double chamfered or chamfered on top with a washer faced bearing surface. They are most commonly used in construction and engineering applications and paired with heavy hex (structural) bolts.

Alloy 400 is a solid solution alloy that can only be hardened by cold working.

Hex bolts are used to fasten two or more parts together to form an assembly either because it cannot be manufactured as a single part or to allow for maintenance and repair disassembly. By definition “A Bolt is a headed and externally threaded mechanical device designed for insertion through holes in assembled parts to mate with a nut and is normally intended to be tightened or released by turning that nut.” When used with a preformed internally threaded (tapped) hole, the hex bolt’s head is turned to tighten, which technically makes it a screw (see our Tech Data section for a discussion regarding the differences between bolts and screws). Hex bolts are also known as: hex head bolts, cap screws, hex cap screws, hex head cap screws, machine bolts, hex machine bolts, hex head machine bolts and, if fully threaded, tap bolts, hex tap bolts and hex head tap bolts. A hex bolt is often differentiated from a hex cap screw by its underhead bearing surface: if it has a circular boss, called a washer face, it’s a hex cap screw¡ªif it doesn’t then it’s a hex bolt.

Inconel 601 fasteners are designed to withstand severe corrosion and high temperature exposure. These fasteners contain nickel and chromium alloys for excellent corrosion, heat and oxidation resistance. Nickel content retains ductility and high temperature strength after prolonged use. Fasteners of this grade produce a tightly adherent scale that resists spalling under severe thermal cycling conditions.
