An age hardened super alloy with exceptional strength at high temperatures

• Extreme high temperature strength
• Service temperatures up to 1600°F (870°C)
• Very oxidation resistant
• Waspaloy chemistry & specifications
• Datasheet for Waspaloy
• Waspaloy pan head screw features and benefits

Waspaloy pan 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 pan 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 Pan Head Screw Features and Benefits

Pan head screws are flat on top and rounded on the sides. Waspaloy pan head screws are ideal for:

• Small diameter fasteners – especially when the fastener size needed is too small for a wrench.
• When phillips or slotted drivers are desired. For many high strength specialty alloys, only slotted drives are available.
• Low torque applications because the drivers don’t offer as much force as a wrench.
• Large diameter head provides more clamping area.

How Are They Different from Button Head Screws?
Waspaloy pan head and button head screws have very similar profiles however, button head screws allow for a hex socket driver whereas pan head screws do not.

Waspaloy Chemistry & Specifications

Waspaloy is a solution annealed and age hardended alloy which provides its high strength properties. There are a few aging varieties however the AMS 5708 is one of the more common.

Waspaloy Specifications: UNS N07001, ASTM B 637, AMS 5708, AMS 5709, EN 2.4654, Werkstoff 2.4654
