Abstract: A metal nut (N) is held by a plastic clip-body (12). The clip-body (12) has first and second arms (16, 18) and an end wall (20) that form a closed end and an open end (6). The open end (60) includes cam surfaces for camming a member (M) into the open end (60). It also includes an annular locator wall (28) that extends upwardly from the second arm (18). The upper end of this locator wall is formed to slope upwardly as it extends inwardly from the open end of the clip-body (12). The sloping upper end of the locator wall (28) helps to cam the member (M) into the clip-body (12). The clip-body (12) includes a first arm (16) having sidewalls (36, 38) that extend outwardly from the arm (16).

Abstract: A fastener structure for fastening a first member and a second member using a taper implant having a threaded hole therein. The taper implant has a frusto-conical outer surface, a projecting portion connected to a larger diameter end and a threaded hole passing therethrough. The first member has a wall portion with a tapered hole extending therethrough and a counterbored portion adjacent a larger diameter end to receive the projection portion of the taper implant. The taper implant is inserted into the hole of the first member and held therein by frictional contact. The second member has a wall portion with a hole therethrough. The second member is positioned in contact with the first member and the two members are fastened together by inserting a male screw through the hole of the second member and threading the male screw into engagement with the threaded hole of the taper implant.

Abstract: A taper implant includes a taper portion having an outer surface frust-conical in shape. A flange portion is formed at an outermost end of the taper portion on the larger-diameter side to project outwardly with respect to the taper portion and having a flat surface situated perpendicularly to the axial direction of the taper portion, and female threads serving as a fit portion extending in the axial direction of the taper portion. A hole taper portion and a hole step portion are drilled at the same time to bore a hole in one of the members to be fastened, and the taper implant is driven into the hole, thereby providing a screw fastening structure for the fastened members.

Abstract: An insert according to the present invention has a very low transverse Coefficient of Thermal Expansion. This is the result of an isolation and compensation structure formed by a sleeve surrounding a post. The sleeve isolates the post from the thermal expansion effects of the panel. This eliminates the influence of thermal expansion/contraction of both the panel and the bonding material. Since the post itself will also expand and contract with temperature, the attachment point of the post to the sleeve is deliberately selected so as to compensate for the post's own dimensional changes.

Abstract: A jackscrew insert and a method for jackscrew insertion into existing mounting openings in a machine base are described. A jacking shoulder is provided by a modification of the existing mounting openings utilizing a jackscrew machining tool. The jackscrew machining tool includes a cutting edge which cuts the jacking shoulder into the machine base adjacent the existing mounting openings. Should the existing mounting openings not be modified for proper utilization of the jackscrew insert, a jackscrew assembly and method for use are also described.

Abstract: A fastener for securely attaching a board perpendicularly to an edge of a composite board that includes a first portion and a second portion. The first portion includes a dowel that fixedly engages in a blindbore in the edge of the composite board, a washer that removably abuts against the dowel and the edge of the composite board and limits travel of the dowel in the blindbore, glue that is disposed on the dowel and in the blindbore and fixedly engages the dowel in the blindbore, and an installation screw that extends through the washer and threadably into the dowel, and when tightened, holds the first portion together as a unit, while the unit is being installed in the blindbore, and once the unit is installed, the installation screw and the washer are removed, with the glue maintaining the first portion in the blindbore.

Abstract: An adjustable-length closet fastener (1) has a fastener shank (2, 32) with an anchor-ridge head (3, 33) which is sized and shaped for positioning side walls of the anchor-ridge head against walls (5) of a predetermined retainer cavity (6) to arrest rotation of the fastener shank and which is sized and shaped for positioning a fastener shank-side surface (9) of the anchor-ridge head against a ceiling (10) of the predetermined retainer cavity at opposite sides of a shaft orifice in the predetermined retainer cavity to prevent exit of the adjustable-length closet fastener from the predetermined retainer cavity.
