Cobalt Alloy Screws

Cobalt Alloy Screws are specialized fasteners designed for applications requiring superior performance under extreme conditions of high heat, wear, and corrosion. Alloys from the Stellite or Haynes families are utilized for their outstanding hot hardness and resistance to creep and galling (seizing of threads at high temperatures). These attributes make them ideal for securing components in gas turbine hot sections, heat treatment fixtures, and critical pump or valve assemblies where thermal stability and resistance to thread seizure are paramount. Zeron Fastners is a reliable supplier and manufacturer in India, providing certified, high-integrity anti-galling screws for the most demanding, severe service fastening requirements.
