PTFE Coated Nut Red Color. The range of fasteners that benefit for PTFE coatings include studs, bolts, nut and washers in various materials, these include high tensile, stainless steel and forged materials. Previously, hot dip galvanising, cadmium or zinc plating were considered standard, however, with the performance factors that include low coefficient of friction and corrosion resistance, PTFE coatings offer enhanced performance characteristics that includes consistency of tensioning and subsequent ease of installation and removal. An additional benefit of PTFE Coated Nut Red Color for fasteners is the availability of colours, this is most effective for product identification and to identify torque loading limits for differing applications. Nut and bolt connectors life expectancy and corrosion resistance improve dramatically when PTFE coatings are applied.
