PTFE COATED STUDS, BOLTS AND NUTS
PTFE coated fastener’s provides exceptional corrosion resistance, low coefficient of friction, consistent tensioning and subsequent ease of installation and removal.

Extensive testing and field use have proven that the future of coated fastener’s lies with Fluoropolymer coatings. Previously hot dip, galvanized, cadium or zinc plated fastener’s were considered the standard. But these coatings could not stand up to the corrosive atmospheres prevalent in many industries. The most widely used application is on B7 studs with 2H nuts.

Dramatic improvements in efficiency, life expectancy and corrosion resistance are claimed to be imparted to Nut and Bolt connectors by the application of a low friction PTFE coating. PTFE coated connectors have out-performed all others in aggressive any noticeable effect.
