Waspaloy Hex Bolts
Waspaloy (2.4654) Hex Bolts 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 Hex Bolts 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 Hex Head Bolt Features and Benefits
It is important to differentiate between a Waspaloy hex head bolt and hex head cap screw. Often people assume they are the same, but they are actually very different fasteners in terms of how they are manufactured, as well as from an application perspective. Regardless of your choice, Waspaloy hex heads offer strong, stable joints because of their large head service.
The Hex Comparison
| Hex Head Bolts | Hex Head Cap Screw |
| Features flat washer facing under the bolt head. Also called a finished hex bolt. Has tighter tolerances on the body dimensions. Best used for precise applications where tight tolerances on the body dimensions are required.

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 |
Flat Head Screws | Waspaloy flat head screws are most commonly offered in an 82° countersink angle, but can be customized to other angles from 60° -120° and are designed to be flush with the surface. Available in slotted and socket drivers. Phillips, 6-lobe, torx and tamperproof drivers in Waspaloy flat head screws can be made require special manufacturing. | • ASME B18.3
• ASME B18.3.6
• DIN 963 / ISO 2009
• DIN 965 / ISO 7046
• DIN 7991 / ISO 10642 |
Hex Head Cap Screws | Waspaloy hex head cap screws offer the added washer face to the bolt head which is lacking on a hex bolt and tighter dimensional tolerances.
