Waspaloy button head cap screw features and benefits
Waspaloy button head cap screws 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 screws, Waspaloy button head cap screws exceed the strength and stability of Inconel 718 at elevated temperatures beyond 1400°F. In addition, the oxidation resistance of Waspaloy screws make it an ideal materials for high temperature applications like gas turbines engines, and a variety of other aerospace components.

Screw Types: 12 Point Screws, Button Head Cap Screws, Flat Head Screws, Hex Head Cap Screws, Pan Head Screws, Set Screws, Socket Head Cap Screws, Tamper Resistant Security Screws, Torx Screws
Waspaloy Button Head Cap Screw Features & Benefits
Waspaloy button head cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face. Compared to a standard socket head cap screw, Waspaloy button heads have a lower and wider profile. This can be useful when the clamping material is too thin to counter-bore.
Advantages
Wide bearing surface for clamping
Low profile head
