Abstract
A lubricating composition includes about 50 weight percent to about 70 weight percent of a blend including an olefinic resin and a wax. The lubricating composition also includes about 15 weight percent to about 30 weight percent of a fatty acid amide. The lubricating composition further includes about 10 weight percent to about 20 weight percent of a zinc salt of a fatty acid having carboxylate groups each having 8 to 24 carbon atoms.
Claims24
A lubricating composition comprising:
- (a) about 50 weight percent to about 70 weight percent of a blend comprising an olefinic resin and a wax;
- (b) about 15 weight percent to about 30 weight percent of a fatty acid amide;
- and
- (c) about 10 weight percent to about 20 weight percent of a zinc salt of a fatty acid having carboxylate groups each having 8 to 24 carbon atoms.
A coated fastener comprising:
- a fastener body having a surface;
- and
- a coating applied on at least a portion of said surface, said coating comprising a lubricating composition comprising about 50 weight percent to about 70 weight percent of a blend comprising an olefinic resin and a wax, about 15 weight percent to about 30 weight percent of a fatty acid amide, and about 10 weight percent to about 20 weight percent of a zinc salt of a fatty acid having carboxylate groups each having 8 to 24 carbon atoms.
A method of making a coated fastener, said method comprising the steps of:
- providing a fastener having a fastener body with a surface;
- and
- coating at least a portion of the surface with a lubricating composition having about 50 weight percent to about 70 weight percent of a blend comprising an olefinic resin and a wax, about 15 weight percent to about 30 weight percent of a fatty acid amide, and about 10 weight percent to about 20 weight percent of a zinc salt of a fatty acid having carboxylate groups each having 8 to 24 carbon atoms.
A method for mating a fastener with a workpiece having a pilot hole defined by an inner wall portion, said method comprising the steps of:
- providing a fastener having a longitudinal axis, a head and a shank extending from the head, the shank having a threaded region comprising an external helical thread;
- preconditioning at least one of the threaded region and the inner wall portion to include a lubricating composition having about 50 weight percent to about 70 weight percent of a blend comprising an olefinic resin and a wax, about 15 weight percent to about 30 weight percent of a fatty acid amide, and about 10 weight percent to about 20 weight percent of a zinc salt of a fatty acid having carboxylate groups each having 8 to 24 carbon atoms;
- inserting one end of the shank into the pilot hole;
- and
- rotating the head about the longitudinal axis and longitudinally advancing the fastener forward to drive a portion of the shank into the pilot hole and forming a thread in a portion thereof.
