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 set screw features and benefits
Alloy 330 set 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 set screws are found in high temperature applications like vacuum furnaces, heat treating and brazing applications.

Alloy 330 set screws are unique in that they have no screw head, meaning that they have no protruding part past the threaded shaft. They are thread only and are available with a socket or slotted driver insert at one end. Set screws are used to secure an object within or against another object. Typically they secure a rotating part such as a gear or shaft. Alloy 330 set screws are driven through a threaded hole in the rotating part until it is tight against the inner object, preventing from moving relative to the outer object. Set screws are available with various points depending on the application.
This is the most commonly used set screw and is identified by a cup-shaped indentation on one end. Alloy 330 cup points are typically used for a quick, semi-permanent or permanent applications where it is acceptable to cut the cup point edge of the screw.
A cone point is easily identifiable by its sharp cone-shaped point – just like an ice cream cone. Alloy 330 cone point set screws deliver the strongest clamping force due to the deep penetration of the point. As a result they are used for permanent assembly.
The cheapest and simplest of the set screw point styles, this screw has a flat surface on the bottom of the screw. This type is used when you need the ability to frequently change parts and require minimal shaft deformation.
