    摘要: An assembly comprising first and second structural elements having aligned holes, an fastener that occupies at least respective portions of the holes without a surrounding sleeve, and a mating part that is coupled to the fastener. The fastener comprises: a head; a circular cylindrical shank extending from the head; a mating portion comprising external projections; and a transition portion disposed between the shank and the mating portion. The transition portion comprises a first radiused lead-in section that meets the shank at a shank/lead-in intersection and a second radiused lead-in section that meets the first radiused lead-in section. The first radiused lead-in section curves gradually in a first axial direction toward the mating portion and has a first profile that is a circular arc having a first radius, while the second radiused lead-in section curves abruptly in the first axial direction and has a second profile that is a circular arc having a second radius which is much smaller than the first radius.

    摘要: A template kit for assisting with the drilling of holes and the mounting of objects to a planar surface. The template kit includes an impactor, a plurality of punch heads removably securable to the impactor, and a sheet of material having a first side and a second side. The first side includes a first adhesive that can releasably secure the object to be mounted. The second side includes a second adhesive that can secure the device to a wall or other planar surface. The second adhesive has increased adhesive strength relative to the first adhesive. Each punch head includes an inner and outer edge that can cut a disc member from the sheet of material, wherein the impactor drives the punch head through the sheet of material. In use, the disc members are secured to a wall and serve as a guide for drilling a hole to hang the object.

    摘要: A method and apparatus for forming a seal over a hole in a structure. The apparatus comprises a washer, a sleeve, and a fastener. The washer has a first channel. The sleeve has a second channel and an expandable section. The sleeve is positioned inside the first channel in the washer. The fastener has an elongate portion positioned inside the second channel of the sleeve to cause at least a portion of the expandable section of the sleeve to form a first interference fit with the washer.

    摘要: A fence includes first elongated tubular members, each one of which is configured to extend vertically from ends of the first elongated tubular members positionable proximate to a support surface (e.g., the ground). The fence also includes second elongated tubular members extending between the first elongated tubular members, each of which is configured to extend parallel to the support surface. The fence further includes receivers defined by apertures formed in the first elongated tubular members, each of which extends outwardly from respective first elongated tubular members so that each one of the second elongated tubular members can be fixedly attached to corresponding ones of the first elongated tubular members. In some embodiments, one or more of the first elongated tubular members and/or the second elongated tubular members can have a circular cross-section. The second elongated tubular members can be fixedly attached the first elongated tubular members with and/or without welding.
