An age hardened super alloy with exceptional strength at high temperatures

Waspaloy hex head 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 bolts, Waspaloy hex head bolts exceed the strength and stability of Inconel 718 at elevated temperatures beyond 1400°F.  In addition, the oxidation resistance of Waspaloy bolts 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
  • Hex bolts have a flat end and lack the washer face under the head.
  • Appropriate for when mechanical properties are more important than dimensional tolerances.
  • 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.
