More Information
Summary:A screw includes a head portion, an externally threaded shank extending from the head portion, the externally threaded shank having an external surface, and a flow-hole-forming tip disposed at a distal end portion of the externally threaded shank. The flow-hole-forming tip includes a radiused lower zone having an external surface tangent to the external surface of the externally threaded shank, a conical middle zone having an external surface tangent to the external surface of the radiused lower zone, the conical middle zone defining a vertex angle, and a radiused distal end zone having an external surface tangent to the external surface of the conical middle zone. The flow-hole-forming tip includes a width of the flow-hole-forming tip is greater than a length of the flow-hole-forming tip and/or the vertex angle is greater than or equal to 90 degrees.
