High Temperature Graphite Screw And Nut Set

High Temperature Graphite Screw and Nut Set

Overview

Graphite screws and nuts are essential fasteners for high temperature furnace assemblies where conventional steel bolts would oxidize, deform, or fail. These graphite fasteners maintain their mechanical properties at elevated temperatures and are resistant to most corrosive environments.

Our graphite fasteners are precision machined from fine grain isostatic graphite for accurate threads and reliable performance in vacuum furnaces, heat treatment equipment, and semiconductor processing chambers.

FAQ

Q: What size graphite screws do you offer?
A: We offer standard sizes from M3 to M20 in various lengths. Custom sizes can be manufactured based on your requirements.

Q: Can graphite screws be reused?
A: Yes, graphite screws can be reused multiple times as long as the threads are not damaged. Proper handling is important as graphite is brittle compared to steel.

Q: What is the torque limit for graphite screws?
A: Graphite screws require much lower torque than steel screws. We recommend approximately 1/3 to 1/2 of the torque used for equivalent size steel fasteners to avoid thread damage.
