Flourocarbon Coated Bolts & Nuts
Studbolts with Mastercote

MASTERCOTE coated with high PTFE content is best suited for installations in
petrochemical plants, offshore platforms and in corrosive environments.

The resin-like bonded coating provides a low coefficient of friction and excellent resistance to many chemicals and acids. PTFE dry film provides lubricity, thus preventing galling in breaking out.

MASTERCOTE coated products are the best in the market salt-fog-spray tested to 5, 500 hours without a spot of rust.
