An engineered high temperature resistant steel
- Excellent high temperature stability
- Very oxidation and carburization resistant to 2100°F
- Good resistance to thermal shock and quenching
- Alloy 330 pan head screw features and benefits
Alloy 330 pan head screws are specifically designed for high temperature furnace applications. Alloy 330 screws unique combination of properties allow 330 screws to handle thermal shock from quenching, be oxidation and carburization resistant as well as handle thermal cycling well. As a result, alloy 330 pan head screws are found in high temperature applications like vacuum furnaces, heat treating and brazing applications.

Pan head screws are flat on top and rounded on the sides. Alloy 330 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?
Alloy 330 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.
