Nickel Socket Head Cap Screw

SNSN

• Nickel
• Excellent corrosion resistance against sodium hydroxide like alkaline solutions, high-concentration halogen gases and non- oxidative acids.
• Useful in corrosion resistance and heat resistance applications, such as sodium hydroxide gas concentration units, and heat exchangers.
• Clean wash format minimizes gas diffusion and prevents foreign particle inclusion.
