For a complete flange protection system, we recommend including Drake Specialties Nut/Bolt Protector Caps and Corrosion Inhibitor Grease. The Nut/Bolt Protector Caps are plastic caps that snap tightly over nuts to protect stud ends and nuts from corrosion. The caps allow for easy unbolting of flanges and valves.
NOTE: Flange Protectors do NOT prevent lateral spray-outs, and therefore should not be used as safety devices. Flange Spray Shields are designed for spray protection and containment.
While nut caps may be used to eliminate excessive paint buildup on bolt threads, the leading benefit is defending the stud bolt threads and hex nuts from rust and corrosion, thus allowing easy unbolting. Nut Caps are economical, reusable, easily installed, and available in all sizes for heavy hex nuts ranging from 1/2″ to 3″.
