High purity tungsten bolts and screws are designed for extreme temperature and vacuum environments. ZSWMO manufactures customized tungsten fasteners for vacuum furnaces, sapphire crystal growth equipment, semiconductor systems and other high-temperature applications.

Product Overview

High Purity Tungsten Fasteners for Extreme Temperature Applications

ZSWMO manufactures high-performance tungsten fasteners including tungsten bolts, screws, nuts and customized threaded components for demanding industrial environments.

Tungsten is one of the most suitable refractory metals for extreme temperature applications due to its extremely high melting point, excellent thermal stability and outstanding resistance to deformation.

Compared with conventional metal fasteners, tungsten fasteners maintain reliable performance under high-temperature vacuum conditions and are widely used in specialized furnace systems and high-purity thermal equipment.

We provide standard and customized tungsten bolts and screws according to customer drawings, thread specifications and application requirements.
