A fastener is a hardware device that mechanically joins or affixes two or more objects together.

Fasteners can also be used to piping components such as a valve, a pumps, or a maintenance flange; or they may involve keeping together the sides of an opening of flexible material, attaching a lid to a container, etc.

Fasteners used in these manners are often temporary, in that they may be fastened and unfastened repeatedly.

Monel

Amco metals can provide a wide variety of Monel fasteners including; Monel nuts, Monel bolts, sockets, washers and more Monel Fasteners. If we do not have your Monel Fasteners in stock (Inch or Metric) we can have these manufactured to your specification.

Material Notes:

Monel is primarily composed of nickel (up to 67%) and copper, with some iron and other trace elements.Monel alloy 400 is binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines.

Properties:

Compared to steel, Monel is very difficult to machine as it work-hardens very quickly. It needs to be turned and worked at slow speeds and low feed rates. It is resistant to corrosion and acids, and some alloys can withstand a fire in pure oxygen. It is commonly used in applications with highly corrosive conditions. Small additions of aluminium and titanium form an alloy (K-500) with the same corrosion resistance but with much greater strength due to gamma prime formation on aging. Monel is typically much more expensive than stainless steel.

Monel alloy 400 has a specific gravity of 8.83, an electrical conductivity of approximately 3.4% IACS, and (in the annealed state) a hardness of 65 Rockwell B.

Aerospace applications

Monel metal found bulk uses in aircraft construction, especially in making the frames and skins of experimental rocket planes, such as the North American X-15, to resist the great heat generated by aerodynamic friction during extremely high speed flight. Monel metal retains its strength at very high temperatures, allowing it to maintain its shape at high atmospheric flight speeds, a trade off against the increased weight of the parts due to Monel's high density.

Marine applications

Monel's corrosion resistance makes it ideal for marine applications such as piping systems, pump shafts, seawater valves, trolling wire, and strainer baskets. Some alloys are completely non-magnetic and are used for anchor cable aboard minesweepers, housings for magnetic-field measurement equipment. In recreational boating, Monel wire is used to seize shackles for anchor rodes, Monel is used for water and fuel tanks, and for under water applications. It is also used for propeller shafts and for keel bolts. However, because of the problem of electrolytic action in salt water (also known as Galvanic corrosion), in shipbuilding monel must be carefully insulated from other metals such as steel.

K-500 Alloy has similar properties to Monel 400 Alloy, but has the added feature of Age Hardening to achieve a higher strength and hardness, this is due to the addition of aluminium and titanium. K-500 Alloys strength is maintained to temperatures as high as 1200 F, yet stays tough and ductile to temperatures down to -423 F. Along with staying non-magnetic down to -210 F. A common specification for this is QQ N 286.

Nickel alloy fasteners are widely used due to their strength and ductility. Nickel superalloys exhibit high strength coupled with high temperature resistance and are used for high stress, high heat applications.  Wrought nickel alloys are characterized by their anti-corrosive properties as well as the high strength and temperature resistance properties found in the other nickel alloys.  Monel®, Hastelloy® and Inconel® are widely used wrought alloys.  While they do produce high strength fasteners, nickel alloy screws, bolts, nuts and studs are difficult to machine and require special handling to avoid work hardening and brittleness.

Common uses for nickel alloy fasteners include:
  • Food processing or food serving equipment
  • Marine and saltwater equipment
  • Pump and valve components
  • Equipment and components exposed to chemicals, acids and other corrosive materials
  • Exhaust systems, engine components and other high heat equipment.

Eastwood manufactures custom fasteners using all grades of nickel alloys.  We are experienced in working with metals that are difficult to machine and will accommodate the specific properties of the alloys.  We offer full CNC manufacturing and forging production capabilities and can manufacture fasteners with exacting tolerances in non-standard configurations.  We offer custom sizes, shapes and thread configurations. Our fasteners are manufactured to MIL-I 45208 standards and we can manufacture to ASTM, SAE, DIN and customer-defined specifications if required.

We are committed to providing each client with a high quality, production-ready fastener.  Our staff will work with you throughout production to ensure that your fastener meets your requirements.
