| 2-Way Reversible Lock A lock nut that can be installed either side up. Often used in high temperature applications. | Coupling Coupling nuts are long nuts used to connect pieces of threaded rod or other male threaded fasteners. | Slotted Slotted nuts are used in conjunction with a cotter pin on drilled shank fasteners to prevent loosening. | Castle Castle nuts are similar to slotted nuts but with the slots in a rounded section above the main nut. |
| Fastener material and coating |
 |
| Fasteners come in a variety of materials. Selecting a material should be based on such considerations as environment (corrosive or temperature extremes), weight, magnetic properties, stresses, reusability, and expected life. Steel: Most fasteners are made from steel. Specifications cover a broad range of mechanical properties that are indicated by a bolt-head marking system that identifies the fastener by grade. For example, SAE grades 2, 5, and 8 are most often specified. Common steels are SAE 1010 (machine screws, carriage bolts, and other fasteners without critical strength requirements); SAE 1018, 1020, 1021 (bright cap screws, special items); SAE 1038 (high-strength bolts, studs, nuts, cap screws); SAE 1041, 1045, 1330, 1340 (special high-strength requirements), and SAE 1100 series (resulfurized -- usually for nuts). Aluminum: Aluminum alloys are the least costly, by volume, of all fastener metals. Aluminum fasteners are classified as hardenable and nonhardenable and weigh about one-third as much as steel. Some grades equal or even exceed the tensile strength of mild steel. The metal polishes to a high luster, has high thermal and electrical conductivity, is nonmagnetic, can be hardened by alloying, and has high corrosion resistance. Typical fastener alloys are 2024-T4 (cold-formed bolts, screws, rivets, machine-screw nuts), 2011-T3 (milled-from-bar nuts, screws, bolts), 1100 (cold-formed rivets), and 6061-T6 (nuts). Brass: This metal is worked easily into shape and has adequate strength. Tensile strength or hardness is improved by cold working. Some brasses have a greater tensile strength than mild carbon steel, along with a higher resistance to corrosion. The metal is nonmagnetic and takes a high luster. Copper: One of the most malleable of all metals, copper also has good corrosion resistance and the highest conductivity of all the nonprecious metals. Copper：One of the most malleable of all metals, copper also has good corrosion resistance and the highest conductivity of all the nonprecious metals. Copper is alloyed with silicon and manganese or aluminum for greater strength. Lead is added to give free-machining qualities. Typical alloys are high-silicon bronze, type A (hot-forged bolts, nuts; milled-from-bar bolts, nuts, setscrews); low-silicon bronze, type B (cold-formed bolts, nuts, rivets, screws); silicon-aluminum bronze (hot-forged products requiring special properties); and cupro-nickel, a copper-nickel alloy used for high strength and resistance to saltwater corrosion. Nickel: Fasteners can be made from commercially pure (99.4%) metal, Monel, or Inconel. They are used where toughness, immunity to discoloration and corrosion, and strength at high temperatures are desired. Pure nickel: Ideal for applications involving contamination, and strength retention at both high and subzero temperatures. Monel: Combines relative economy with adaptability to cold heading and roll threading. |
| Inconel: Excellent for fasteners that must retain high strength and oxidation resistance at temperatures up to 1,600°F. Stainless steels: Fasteners of this metal are used where corrosion, temperature, and strength are problems. They also produce a mirrorlike finish. There are three basic types: Martensitic: Magnetic and hardenable. Common fastener alloys are Types 410, 416, and 431. Ferritic: Magnetic and not hardenable by heat. Can be cold worked with reasonably good results. Used for economic reasons, and where corrosion-resistance requirements are not too severe. Best fastener alloy types are 430 and 430F. Austenitic: Nonhardenable, nonmagnetic, and offers the greatest degree of corrosion resistance. Typical alloys are 18-8 and 300 series. Titanium：Fasteners made from this material are used chiefly on aircraft. Titanium has excellent corrosion resistance and good high-temperature performance. These fasteners are most commonly used in joints loaded in shear but are also used in tension-loaded joints. Beryllium：Exceptionally lightweight, beryllium fasteners are about 40% as heavy as titanium. Brittleness is a limitation to widespread use. Beryllium bolts are used primarily for applications where the shear requirement is at least 60 ksi. |
