Abstract:
According to the present disclosure, a method for securing a threaded fastener in a threaded hole includes directly applying a locking compound to at least a portion of threads to be mated on either the threaded fastener or the threaded hole. The locking compound includes a substantially pure, non-chromated aluminum pigmented compound suspended in a water-based inorganic binder with temperature resistance in excess of 900 degrees Fahrenheit (about 482 degrees Celsius). The threaded fastener is threaded into the threaded hole after applying the locking compound on the threads to be mated.

Abstract:
A fastener may include a shaft and a head. The shaft may have first and second opposing ends and a first surface having a first diameter. The head may be attached to the first opposing end of the shaft. The head may have a second surface comprising a second diameter which is larger than the first diameter. The head may have a third surface extending between the second surface and the first surface. The third surface may be defined by a relief slot extending from the second surface to at least one of near and to the first surface. The relief slot may be for providing a relief path to reduce pressure during installation, using a viscous compound, of the fastener to a member.
Abstract:
An adhesive is applied to a male-threaded portion of a tapping screw. The male-threaded portion with the adhesive is threadably engaged with a non-threaded through hole of the full-closed stopper with female-threads being formed on the surface of the though hole. In this case, the adhesive functions as lubricant between the inner surface of the through hole and the male-threaded portion. Accordingly, the male-threaded portion can be screwed into the through hole with a low torque and without applying high load to the full-close stopper. Therefore, the full-close stopper is prevented from being projected around the inlet and the outlet of the through hole, and the full-close stopper is prevented from being cracked.
Abstract:
A method and fastener for distributing an anchoring material and securing abutting honeycombed panels in a generally perpendicular alignment. The fastener is provided with a pointed tip to penetrate into undrilled portion of the inner cellular structure of one of the panels. The hollow fastener allows for the injection and distribution of an anchoring material into the ruptured cell core and into predrilled bores in the first panel.
Abstract:
A blind rivet system including a number of parts to be joined that have aligned holes. A tubular rivet body is disposed in the aligned holes and includes a rivet head portion and a sleeve portion. The head portion and sleeve portion include a longitudinal bore. A mandrel having a head portion greater in diameter than the bore and a shaft portion is disposed within the longitudinal bore. An adhesive is disposed in an annular space defined by the interior surface of the bore and an exterior surface of the shaft portion. An installation tool having a seal intersects with the rivet head portion such that when the head portion is drawn within the bore during installation, the adhesive is maintained within the tubular rivet body and extruded from the annular space to a region between faying surfaces of the parts to be joined.
Abstract:
An object of the present invention is to provide an excellent weld nut wherein the weld nut and an iron plate are closely fixed together by inserting extra metal materials upon welding into a groove around a weld projection. The present invention relates to weld nuts each having such a groove in the vicinity of such a weld projection.
Abstract:
A tubular anchor includes a tubular member (1, 21) with a drilling head (2, 22) at one of its end, a load application element (3) extending along a portion of the tubular member opposite the one end, opening (5, 23) provided in a region of the drilling head. The tubular anchor also includes at least one, substantially cylindrical, hollow element (7, 24, 25) for receiving a mortar mass (4, 37, 38) and closed, at its opposite ends, with two displaceable pistons (8, 9; 31, 32, 33, 39), respectively, with one of the pistons being received in a piston-receiving region of the at least one mortar-mass receiving element and facing in a setting direction (S), (6, 35) and at least one through-opening (11, 34) spaced from a free end of the piston-receiving region (6, 35) by a distance (a, b) corresponding at least to a length (l) of the piston (8, 32) received therein.
Abstract:
An electrically insulated anchor device is described, comprising a rigid elongated metal sleeve including an external surface that leads from an open top end to a bottom end. A longitudinal internal bore is formed within the sleeve with a bore wall spaced from the external surface by a sleeve wall thickness dimension. An electrically insulative polymer insert with an external surface engages the bore wall within the sleeve. The insert further includes a fastener receiving bore defined by a fastener receiving wall spaced from the external insert surface by an insert wall thickness dimension. The sleeve wall thickness dimension is substantially greater than the insert wall thickness dimension.
Abstract:
A break-away lug nut positioner for holding lug nuts on a race car wheel to facilitate more rapid tire changes during pit stops. The break-away lug nut positioner includes a spacer that supports a lug nut at a proper distance over a mounting hole of a race car wheel. That is, the spacer holds the lug nut so that it is adjacent to a threaded mounting stud when the wheel is held flush against the race car hub. During installation, the lug nut is driven into the spacer cavity, forcing the spacer to break into pieces. The adhesive bond between the lug nut and the spacer is weaker than the individual pieces of the spacer, which causes the spacer to separate cleanly from the lug nut, allowing the lug nut to seat properly against the wheel mounting plate. That is, the adhesive and the material and configuration of the spacer are selected so that the spacer breaks cleanly away from the lug nut, and no spacer material remains between the lug nut and the mounting plate.
