Titanium Socket Head Cap Screw

SNST

• Titanium
• The specific gravity of titanium is approximately 60% that of stainless steel.
• For use in lightweight applications in automobiles, aircrafts, spacecrafts, medical instruments, and robots.
• Completely Nonmagnetic (0 Magnetic Flux Density).
• Nonmagnetic characteristics may be used with FPD (Flat Panel Display) and semiconductor production equipment and devices, and electronic equipment.
• Excellent chemical and seawater resistance for electrochemical plating and aquatic applications.
• Chemical Polish and Shine Polish improve surface roughness, minimizing gas diffusion and foreign particle inclusion.
• Material/Finish
• TB340C (Type II Titanium)
