Waspaloy Lock Nuts
Waspaloy (2.4654) Lock Nuts are known for their superb high strength at elevated temperatures. Waspaloy is a high performance nickel alloy combined with cobalt, chrome and molybdenum to create it’s unique combination of strength and high temperature stability.
Similar to that of Inconel 718 fasteners, Waspaloy Lock Nuts exceed the strength and stability of Inconel 718 at elevated temperatures beyond 1400°F. In addition, the oxidation resistance of Waspaloy fasteners make it an ideal materials for high temperature applications like gas turbines engines, and a variety of other aerospace components.

Waspaloy Locknut Features and Beneifts
A waspaloy locknut resists loosening from vibrations and torque. One of the most common styles is a prevailing torque locknut. This kind of waspaloy locknut has a prevailing torque feature which deforms elastically, preventing it from freely spinning like a standard nut.
The two most common and reliable forms of prevailing torque locknuts are the flexloc style and the polymer insert lock nut. A waspaloy flexloc nut is all-metal in composition with a segmented collar that creates six “locking fingers,” that act as a spring. Waspaloy polymer insert lock nuts are often referred to as nylon insert locknuts, although various high performance polymers can be used for the screw threads to “bite into.” Both flexlock and polymer insert locknuts are available in both hexagonal and 12 point configurations.

Other all metal lock nuts available include the waspaloy stover and elliptical styles. Though these styles are often a cheaper initial cost, they are less reliable than the flexloc style. As these styles delivering less prevailing torque cycles and often result in more failures, the flexloc style is a better investment for both reliability and cost savings.

Waspaloy Screws
12 Point Screws | Waspaloy 12 point screws allow for higher torque to be applied than a socket head cap screw or head head bolt, however they are be less economical due to the complex head design. Available in 1/4" or larger sizes. | • IFI-115
• MIL SPEC
• DIN 34822
• DIN 34821 |
Button Head Cap Screws | Waspaloy button head screws offer a wide clamping area and low profile. They are best for fastening material that is too thin to counter bore. | • ASME B18.3
• ASME 18.3.4M
• DIN 7380 / ISO 7380 |
