    摘要： A steel fastener has an elongate shank, an enlarged head formed at one end of the shank, and a generally pointed tip formed at the other end of the shank. A grooved portion of the shank is formed with helical grooves defining helical ribs and with annular grooves defining annular rings. The shank has a cylindrical portion between the grooved portion and the tip and a cylindrical portion between the grooved portion and the head. Each of the annular grooves has a root where deepest and each of the annular rings has a crest where largest. The roots define an imaginary cone diverging toward the tip. The crests define an imaginary cone converging toward the tip. The shank has an exterior surface coated with a polymeric coating, which is formed from an aqueous composition containing a water-based acrylic resin and a water-based polyurethane resin. A zinc layer and a chromate conversion layer are provided between the polymeric coating and the exterior surface of the shank.

    摘要翻译： 钢制紧固件具有细长的柄，形成在柄的一端的扩大的头部，以及形成在柄的另一端的大致尖的尖端。 柄的开槽部分形成有限定螺旋肋的螺旋槽和限定环形环的环形槽。 柄部在开槽部分和尖端之间具有圆柱形部分，并且在凹槽部分和头部之间具有圆柱形部分。 每个环形槽具有最深的根部，并且每个环形环具有最大的波峰。 根部定义了朝向尖端发散的假想锥体。 波峰限定了朝向尖端收敛的假想锥。 柄部具有涂覆有由包含水基丙烯酸树脂和水基聚氨酯树脂的水性组合物形成的聚合物涂层的外表面。 在聚合物涂层和柄的外表面之间提供锌层和铬酸盐转化层。

    摘要： A nail having a plurality of grooves configured to reduce the amount of material needed to create the nail and increase the holding power of the nail, while only minimally affecting the bending yield strength of the nail and other important properties. The nail includes a relatively high number of grooves having a relatively shallow depth to retain a cross-sectional geometry of the shank that permits the formation of a full round head of sufficiently large diameter such that pull through resistance of the nail is not significantly affected. Various embodiments of such a nail are disclosed. In a first embodiment, the grooves are semi-circular and are disposed evenly and symmetrically about the circumference of the shank. In a second embodiment, a protrusion is formed at one tangent point (corner) of each of the plurality of grooves. In a third embodiment, a protrusion is formed at each tangent point of each of the plurality of grooves. In other embodiments the grooves may be unevenly and asymmetrically disposed about the circumference of the shank, the grooves may comprise non-semi-circular geometries and the grooves may comprise deformations.

    摘要翻译： 具有多个凹槽的钉子，其构造成减少产生钉子所需的材料的量并增加钉子的保持力，同时仅最小程度地影响指甲的弯曲屈服强度和其它重要性质。 钉子包括相对较多数量的具有相对浅的深度的凹槽，以保持柄的横截面几何形状，允许形成足够大直径的全圆头，使得钉的拉过阻力不会受到显着影响。 公开了这种钉的各种实施例。 在第一实施例中，槽是半圆形的，并且围绕柄的圆周均匀和对称地设置。 在第二实施例中，在多个槽中的每一个的一个切点（角部）处形成突起。 在第三实施例中，在多个槽中的每一个的每个切点处形成突起。 在其它实施例中，凹槽可以围绕柄的圆周不均匀地和不对称地设置，凹槽可以包括非半圆形几何形状，并且凹槽可以包括变形。
