摘要： A steel pin is disclosed of a type to be forcibly driven into a steel substrate by using a powder-actuated tool. The steel pin has a substantially cylindrical shank, and a substantially sharp point which extends from one end of the substantially cylindrical shank, which conforms substantially to a tangent or secant ogive except for a substantially spherical tip having a radius in the range of approximately 0.015 inch (approximately 3.75 millimeters) to approximately 0.03 inch (approximately 7.5 millimeters), which has substantially true concentricity, which has surface-texture irregularities with a roughness-height index value not greater than approximately 30 microinches (approximately 0.76 micrometers), and which appears to be substantially free of other surface imperfections when viewed under 60.times. magnification. Optimally, the ogive is a tangent ogive with an ogive radius approximately ten times the shank diameter and with an ogive length approximately twice the shank diameter, and the tip radius is approximately 0.1 times the shank diameter. The substantially cylindrical shank is joined to the substantially sharp point at a transition having a substantially smooth, continuously curved surface, and which is knurled near the transition. The steel pin is made by deforming a length of steel wire, as by forging or swaging, so as to form the steel pin.

Optimally, the ogive is a tangent ogive with an ogive radius about ten times the shank diameter and with an ogive length about twice the shank diameter, and the tip radius is about 0.1 times the shank diameter. The substantially cylindrical shank is joined to the substantially sharp point at a transition having a substantially smooth, continuously curved surface, and is knurled near the transition. The steel pin is made by deforming a length of steel wire, as by forging or swaging, so as to form the steel pin with the substantially cylindrical shank and with the substantially sharp point and reshaping the substantially pointed end, as by barrel finishing.
