20090047093 | THREAD LOCKING/PREVAILING TORQUE FASTENER AND FASTENER ASSEMBLY - A thread locking fastener assembly comprising a nut anchor defining an internal thread having a longitudinal axis, a leading face and a trailing face, the internal thread, in axial section, having a profile which is symmetric about a first imaginary line extending radially out from the axis, and a fastener shank having an external thread with a longitudinal axis, a leading face and trailing face, the external thread being received in said internal thread so that said axes are substantially coincident. The external thread, in axial section, has a profile with a radially inner base zone which is symmetric about a second imaginary line extending radially from the shank axis and a radially outer deflectable addendum which is not symmetric about that line so that the addendum prevents axial centralization of the external thread profile in the internal thread profile unless a sufficient axial force is applied to the shank to deflect the addendum. | 02-19-2009 |
20090080996 | BOLT FASTENING METHOD AND APPARATUS - An elasticity limit (limit of yieldingness resistance) of a fastened member (bolt's seat face) increases (an elasticity area expands) due to a plastic deformation of the fastened member by fastening a bolt in an initial fastening step, and the plastic deformation (yieldingness) of the fastened member is properly prevented from progressing even if a thermal stress acts after a final fastening step. Thus, decrease of a fastening shaft force of the bolt can be prevented properly despite removal of the thermal stress. | 03-26-2009 |
20090092461 | FASTENER WITH ZONED, VARYING WAVE-FORM THREAD - A threaded fastener includes a shank having a tip and a head configured for engagement by an associated driving tool. The fastener is configured for use with an associated threaded opening. The head is disposed on the shank opposite the tip. The shank has a helical thread formed thereon. The thread extends from about the tip to about the head and defines a plurality of zones. Each zone has a plurality of individual threads extending 360 degrees about the shank. A leading thread in each zone is formed with a wave-form profile having an amplitude that is greater than the amplitude of each prior leading thread.

20090116929 | THREAD PROFILE MODIFICATION FOR CONTROLLED STIFFNESS - The thread form can provide a controlled thread stiffness which can more evenly distribute loads and can be less sensitive to changes in relative pitch. The controlled stiffness of the thread can provide a desired cantilever bending of the thread under assembled load. The thread form can utilize a traditional thread form at and/or above the pitch diameter, thereby maintaining the area of contact close to that of a standard thread form. Standard gaging implements can be used to ascertain the thread pitch and for quality control. The thread form includes a side extending between the crest and the root. The side has a first portion extending from the crest toward the root and the second portion extending from the first portion toward the root. The first and second portions extend toward the root in different orientations relative to the thread. | 05-07-2009 |
