High purity molybdenum bolts, nuts and fasteners are designed for extreme temperature and vacuum environments. ZSWMO manufactures custom molybdenum fastening components for industrial furnaces, semiconductor equipment and high-temperature applications.

Product Overview

High Purity Molybdenum Fasteners for High Temperature Furnaces

ZSWMO manufactures high temperature molybdenum fasteners including molybdenum bolts, nuts, screws, washers and threaded components for demanding industrial applications.

Unlike conventional metal fasteners, molybdenum fasteners maintain excellent mechanical stability in high-temperature vacuum environments due to their high melting point, low thermal expansion and outstanding resistance to thermal stress.

Our molybdenum bolts and nuts are widely used in vacuum furnaces, sapphire crystal growth equipment, semiconductor manufacturing systems and other high-temperature processing equipment.

We provide standard and customized molybdenum fasteners according to customer drawings, thread specifications and application requirements.
