摘要： A cleaning tool is disclosed for cleaning an object (e.g., a threaded fastener) and retaining debris from cleaning the object. The cleaning tool can comprise a housing operable to be rotated by hand or by a hand tool, and a cleaning chamber formed through the housing. A plurality of retaining cavities are formed through the housing and in fluid communication with the cleaning chamber, and a plurality of cleaning elements (e.g., shafts having bristles) are supported by respective retaining cavities, such that a portion of the cleaning elements (e.g., wire bristles) extend into the cleaning chamber for cleaning the object upon rotation of the housing relative to the object. Elastic elements can be supported by the housing for biasing the cleaning elements to accommodate cleaning different sizes of objects. Associated systems and methods are provided.

摘要： A rotational cutting tool includes a connecting end for engaging with a driving tool and a cutting end for engaging with the work piece. The connecting end and the cutting end rotate about the rotation axis upon rotation of the rotational cutting tool. An inner periphery of the cutting end defines a receiving space for receiving the work piece. The receiving space has a conic surface which extends radially and obliquely with respect to the rotation axis. The receiving space includes a first ridge forming at least one cutting edge for trimming the workpiece and at least one slot allowing trimmed pieces from the workpiece to exit from the receiving space. The first cutting edge extends radially and obliquely with respect to the rotation axis. The first cutting edge extends curvedly and has a curved contour.

摘要： A high-strength screw (1) includes a head (2) and a threaded portion (5) including a thread (6) and a thread end (9) facing away from the head (2) in an axial direction. The threaded portion (5) includes an unhardened portion (12) starting at the thread end (9) and extending in an axial direction. The unhardened portion (12) has a hardness being reduced compared to an axial middle portion (11) of the threaded portion (5).

摘要： Disclosed is a thread chase or tap capable of being inserted past damaged threads of a female threaded coupling and then rotated back to repair the damaged threads. The thread chase can be selectively expanded to engage chase blocks having cutting teeth against threads. Thereafter, a user can rotate the thread chase in a direction sufficient to cause the thread chase to move axially out of the female threaded coupling. Upon doing so, the chase blocks can be pushed outwardly and engage undamaged threads, and rotated so as to move upward and repair damaged threads.

摘要： A method of machining a screw is provided that is capable of preventing formation of a protruding section at a thread tip section. A thread is formed by cutting on a cylindrical body, and a surface of the thread is plastically deformed by rolling. Because of the cutting, a width between-side surfaces of a thread tip section is in a narrowed state as compared to a normal width. This width is narrowed toward a tip of the thread while a thread body section has a width expanded as compared to a normal width. Consequently, the side surfaces are formed to bulge by an excess thickness portion as compared to normal side surfaces. The rolling plastically deforms both side surfaces to cause the excess thickness portion to plastically flow toward the side surfaces.

摘要： A driver for applying torque to threaded fasteners has a plurality of teeth extending along and projecting outwardly from a longitudinal axis of a body on which the teeth are located. The teeth have a helical twist about the longitudinal axis. Each tooth has an angularly oriented engagement surface which is engageable with similarly angularly oriented surfaces within recesses in the head of a compatible fastener. When the driver engages the recesses torque applied to the driver draws the driver deeper into the recesses as the engagement surfaces react against and slide over the angularly oriented surfaces within the recesses. The torque also causes the fastener to turn and advance or retract depending upon the sense of the torque and the angles of the engagement surfaces and the angles of the surfaces within the recesses. The fastener and its method of manufacture are also disclosed.

摘要： A barrel nut with features for reducing tensile stresses under heavy load within the barrel nut has a partial-cylindrical body having a first planar end surface and a second planar end surface. A threaded bore extends through the partial-cylindrical body with a central axis substantially parallel to the first planar end surface and the second planar end surface. At least one groove is formed in each of the first planar end surface and the second planar end surface, the groove having a rounded surface extending at least a part of a distance between a curved upper surface of the partial-cylindrical body to a bottom surface thereof in a direction substantially parallel to the central axis of the threaded bore.

摘要： A wire thread insert comprises besides a cylindrical helix consisting of a plurality of coils a moving tang projecting into the interior of the helix for installing the wire thread insert into a receiving thread. The wire thread insert is connected to the cylindrical helix via a bending portion such that the moving tang can be redressed into the receiving thread after installation of the wire thread insert. The wire thread insert is installed by means of an installation tool with a mounting spindle, which installs the wire thread insert in the receiving thread via a moving shoulder and the moving tang. A compression blade provided at the mounting spindle bends the moving tang back into the receiving thread while the mounting spindle is removed from the installed wire thread insert.

摘要： A fastener system is provided. The fastener system includes a pair of nuts having a beveled end and opposed flats, a nut housing having a cavity, the cavity including an end wall with an aperture and a tapered interior portion to engage the beveled end, and opposing internal flats to engage the nut flats, a resilient member to urge the beveled ends against the tapered portion; and retaining element. The nuts may include tapered thread edges to accommodate damaged male threads, or cutting thread edges to repair damaged male threads.
