摘要： A self-attaching fastener including a central pilot, an annular flange surrounding the pilot including an annular groove having bottom, inner and outer side walls, wherein the bottom wall includes a first plurality of spaced anti-rotation elements each having a radial top face inclined above the bottom wall and a second plurality of circumferentially spaced anti-rotation elements each having a radial top face oppositely inclined below the bottom wall and a method of attachment which avoids distortion of the thread cylinder of a female fastener.

摘要： A method of forming a female fastener including rolling a body portion strip having a midportion and flange portions on opposed sides of the midportion, piercing spaced openings through the midportion, cutting the strip to length between the openings, cold forming a separate generally cylindrical pilot portion having a length greater than the width of the midportion and a diameter greater than the opening through the midportion, preferably including radial splines, and press fitting the pilot portion through the opening in the midportion. The self-attaching female fastener thus includes a rectangular body portion and a generally cylindrical pilot portion having an end face spaced above a plane of the midportion and may be formed of a harder metal than the body portion.

摘要： The present invention is an assembly and method for continuously manufacturing fasteners. A die press actuated at a first speed receives the contoured wire into a die having a piercing element for piercing an aperture and a cutting element for cutting a fastener from the wire. A guide receives the fasteners from the die press and a drive unit engages the fasteners oriented by the guide and conveys the fastener to an elevated height relative to a tapping device. The guide redirects the fasteners by a first router. The fasteners are gravity fed into the first router and redirected to one of the tapping devices. Each tapping device has a tapping element for forming internal ribs in the aperture of the fastener. The tapping devices each actuates at a second speed that in aggregate is generally equal to the first speed of the die press.
