Patent number: 8740531Abstract: A screw includes a positioning member defined on inclined cutting planes of a drilling portion of the screw for stably allowing a cutting edge constructed at a convergence of the cutting planes to cut efficiently. A threaded section formed on a shank of the screw is extended toward the cutting edge and connected with one end of the cutting edge. The positioning member helps the screw fixedly stand on an object. The cutting edge and the cutting planes allow cutting debris to be swiftly and smoothly extruded therefrom into the threaded section for avoiding the piling of the considerable cutting debris. Thereby, the screwing torque is reduced and the drilling speed is promoted. Preferably, the fastened screw is sunken in the object, and the fastening operation is completed successfully.Type: GrantFiled: August 31, 2011Date of Patent: June 3, 2014Assignees: Taiwan Shan Yin Int'l Co., Ltd., Biomate Medical Devices Technology Co., Ltd.Inventors: Kou-Tsair Su, Yu-Jung Su

Patent number: 8708627Abstract: A wheel lug nut locking device having first and second planar sections, each with an opening adapted to be fitted around a wheel lug nut. The planar sections are connected by a flexible section that allows the planar sections to be moved relative to one another. In a preferred embodiment, the flexible section has a concertina-like structure. In use, the locking device is used to lock a wheel lug nut to an adjacent wheel lug nut, so as to prevent or reduce rotation of the wheel lug nut. A plurality of locking devices can be fitted to a single wheel so that all of the lug nuts are operatively locked to an adjacent lug nut. The resulting locking system can be rapidly installed on each lug nut on all wheels, so as to provide improved safety aspects.Type: GrantFiled: July 10, 2009Date of Patent: April 29, 2014Inventor: Ifor C.
