Coated threaded fasteners

A fastener resistant to deposition of corrosion preventative material comprising:

• a threaded portion adapted for uniform engagement with a mating fastener;
• a TEFLON.RTM. powder type coating deposited on said threaded portion to form a substantially uniform layer providing at least one of a masking, lubricating and insulating covering on said threaded portion of said fastener, said fastener being heated to a temperature sufficient to enable said TEFLON.RTM. type powder to adhere to said threaded portion, prior to deposition of said TEFLON.RTM. type coating;
• said fastener being capable of exhibiting substantially uniform torque-tension curve behavior during coupling.

A fastener resistant to deposition of corrosion preventative material comprising:

• a threaded portion adapted for engagement with a mating fastener;
• and
• a TEFLON.RTM. powder type coating deposited on said threaded portion to form a substantially uniform layer, said uniform layer providing an insulating barrier for at least two seconds at about 500 to about 600 volts electrical potential applied across said uniform layer, said fastener being heated to a temperature sufficient to enable said TEFLON.RTM. type powder to adhere to said threaded portion, prior to deposition of said Teflon.RTM. type coating.

A threaded fastener comprising:

• a heat at one end;
• and
• a threaded shank associated with said head having a coated tip portion at the other end, at least a portion of said coated tip being coated with at least one of a lubricating material, an insulating material and a masking material, said coated tip portion being capable of reducing and preventing binding when installed through a fibrous material into an article, said fastener being heated to a temperature sufficient to enable said at least one of the lubricating material, insulating material and masking material to adhere to said portion of said coated tip, prior to deposition of said at least one of the lubricating material, insulating material and masking material.
