SCREW-TYPE FASTENER FOR CONCRETE AND HURRICANE RESISTANCE APPLICATIONS
A screw for use concrete and hurricane applications includes a head end, a shank and a tapered end. A high thread begins on the tapered end, extends onto the shank and terminates at a first axial location along the shank, wherein the high thread defines a high peripheral edge, and at least a first helical portion of the high peripheral edge includes a plurality of notches and the first helical portion extends from on or proximate to the tapered end and substantially to the first axial location. A low thread begins on the tapered end, extends onto the shank and terminates substantially at the first axial location such that an axial length of the low thread is substantially the same as and contiguous with an axial length of the high thread. The low thread defines a low peripheral edge that is free of any notches.
一种用于混凝土和飓风应用的螺钉，包括头端、柄部和锥形端。高螺纹始于锥形端上，延伸到柄部上，并终止于沿柄部的第一轴向位置，其中高螺纹限定高周围边缘，并且高周围边缘的至少第一螺旋部分包括多个凹口，并且第一螺旋部分从锥形端上或锥形端附近延伸，并且基本上延伸到第一轴向位置。低螺纹始于锥形端上，延伸到柄部上，并且基本上终止于第一轴向位置，使得低螺纹的轴向长度基本上与高螺纹的轴向长度相同并且相邻。低螺纹限定了没有任何凹口的低周围边缘。
