Waspaloy flat head screw features and benefits
Waspaloy flat head 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 flat head 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.

Waspaloy Flat Head Screw Features and Benefits
Waspaloy flat head screws are characterized by having a head with a top flat surface (which can feature either a slotted, phillips or allen driver) and bottom that is cone shaped or countersunk. With this design, the head of the screw can align flush or below the surrounding surface having obvious benefits.

Countersink Angle
For most flat head screw designs the angle of countersink is usually 82° for UNC and UNF applications however other angles ranging from 60° -120° could be specified.
| Thread Type | Normal Flat Head Countersink Angle |
UNC / UNF | 82° |
| Aerospace | 100° |
| ISO Metric / Imperial | 90° |
