摘要： Disclosed herein is a tapping screw (1) exerting an excellent anti-loosening effect with regard to a workpiece made of a soft material such as resin and an aluminum alloy. The tapping screw (1) includes a shaft part (3), and a normal thread (10) which is formed on the outer circumferential surface of the shaft part. A clearance groove (20) is formed by cutting out a portion of a ridge of the normal thread, and an engaging protrusion (30) is provided on a bottom of the clearance groove along a portion or an entirety of an edge of the bottom that continuously extends from a flank surface of the normal thread. The tapping screw (1) exerts an excellent anti-loosening effect even when a workpiece expands, contracts or oscillates because the engaging protrusions (30) are embedded into portions of the workpiece which have been embedded into the clearance grooves (20).

摘要： The present invention provides a tightening structure with which a reduction in processing steps is achieved without modifying the shape of a partner member and improvements in bolt strength and fatigue strength are achieved, and with which the fitting length of a thread ridge is not altered greatly in comparison with a conventional tightening structure such that a size reduction can be achieved, thereby contributing greatly to a reduction in the weight of a vehicle.
A self-forming screw having a strength of 14T, which is manufactured by pre-heat treatment rolling and gradually self-forms an internal screw, is used as a tightening bolt, and a member having a prepared hole formed by casting alone or by forging alone, while not yet being subjected to screw formation, is used as a member into which the self-forming screw is screwed.
Following tightening of an attachment member, the tightening structure has a percentage of thread engagement of 75 to 90% between the internal screw formed through self-forming and an external screw, and a fitting length of d to 2.2 d (in the case of a steel cast member or a steel forged member, d being the screw diameter), or of d to 2.5 d (in the case of an aluminum die-cast member) which is obtained between the screw and the prepared hole.
Moreover, the screw is fastened through self-forming, and therefore no clearance is generated on a contact surface between the external screw and the internal screw.

摘要： The present invention relates to a tapping screw to be coupled by machining a female screw and, more specifically, to a general-purpose tapping screw which can be used for all injection-molded objects such as synthetic resin or the like, flexible metal and hard metal. The present invention provides a general use tapping screw, which is a two-line screw having a cylindrical body, and main threads and auxiliary threads which are formed on the outer circumferential surface of the body, wherein the outer diameter of the auxiliary threads is 92ˆ¼97% the outer diameter of the main threads, the angle of the front flank surfaces of the main threads and the auxiliary threads is in the range of 12±3 degrees, the angle of the rear flank surfaces of the main threads is in the range of 25±3 degrees, the angle of the rear flank surfaces of the auxiliary threads is in the range of 20±3 degrees, and intervals between a first pitch from the main thread to the auxiliary thread and a second pitch from the auxiliary thread to the next main threads have a difference in the range of ±10-20%. The present invention also provides a coupling method using the same.

摘要： A thread forming screw for cold forming internal threads in a workpiece comprised of a low ductility material, such as magnesium and the like. The screw uses primarily compressive forces to form the internal threads in the workpiece. The screw has a shank (16) having an entering end and a head end. External threads (24) are disposed on the shank (16). The external threads (24) define a thread configuration with an angle (66) measuring substantially within the range of ninety degrees to one hundred and twenty degrees.
