| 20100247269 | THREADED MEMBER WITH ANTIRUST EFFECT - The present invention provides a threaded member with antirust effect. An oil reservoir is formed inside the threaded member and multiple conduits are formed on an outer circumference of the stem body of the threaded member in communication with the oil reservoir. An absorption material is installed in the oil reservoir and soaked with an antirust liquid. The antirust liquid in the oil reservoir can slowly seep out of the conduits to the outer circumference of the stem body so as to protect the threaded member from rust. | 09-30-2010 |
| 20110158767 | REDUCED MATERIAL, CONTENT FASTENERS AND SYSTEMS AND METHODS FOR MANUFACTURING THE SAME - Reduced material content fasteners are provided that have a reduced material content portion between working ends allowing the fastener to have less weight with equal or better break and torque strengths. Systems and methods are provided for manufacturing reduced material content fasteners that provide for cold working the initial material to reduce the material while work hardening the remaining material. The cold working is provided by rolls and/or dies. | 06-30-2011 |
| 20110268533 | BOLT AND MANUFACTURING METHOD OF BOLT - A bolt has a male screw with a surface hardening portion that has an increased surface hardness and that is applied with a compressive residual stress. The male screw is formed by cutting the bolt, and performing a process to provide at least on the surface of the male screw of the bolt the surface hardening portion that has increased hardness and that is applied with a compressive residual stress. As a result, the fatigue resistance of the male screw is improved and the bolt is effective for use in a portion where the male screw is subject to a repetitive stress. | 11-03-2011 |
| 20110286815 | Method and apparatus for molding a high-strength non-metallic fastener having axially-aligned fibers - A method and apparatus for molding a high-strength, non-metallic fiber-reinforced threaded fastener, such as a bolt or the like. A non-metallic preform (e.g., a solid rod) having longitudinally-extending fibers running therethrough is located in a mold. A mold insert is positioned at the top of the mold, and a penetrator having a pointed tip is located at the bottom of the mold. Upper and lower press plates are closed against the mold insert and the penetrator. Accordingly, the upper press plate moves the mold insert against the top of the preform in the mold to form the bolt head. The lower press plate moves the penetrator against the bottom of the preform, whereby the penetrator is embedded therewithin. By virtue of the embedded preform, the molded fastener will have axially-extending fibers which are compressed into the threads and run in substantially parallel alignment to better resist failure under load conditions. | 11-24-2011 |
