High purity tungsten bolts are designed for extreme temperature and vacuum environments. ZSWMO manufactures custom tungsten screws and fasteners with precision machining for industrial furnace applications.

Product Overview

High Purity Tungsten Bolts for Extreme Temperature Applications

ZSWMO manufactures high temperature tungsten bolts and screws for demanding industrial environments.

Tungsten is an ideal material for extreme temperature fastening applications because of its:

• Extremely high melting point (3422℃)

• Excellent high-temperature strength

• Low thermal expansion

• High wear resistance

• Excellent vacuum stability

Compared with conventional metal bolts, tungsten bolts maintain reliable mechanical performance in high-temperature vacuum environments.

Our tungsten fasteners are widely used in:

• Vacuum furnaces

• Sapphire crystal growth equipment

• Semiconductor manufacturing equipment

• High-temperature fixtures

• Special industrial systems
