| 076114000 | Wrenches | 6 |
| 20100043601 | Methods for Manufacturing Combination Wrenches Without Generating Carbon Scale - A method for manufacturing combination wrenches includes preparing a material plate having a plurality of wrench material pieces. Each wrench material piece is sheared off from the material plate and then pressed in a sealed mold at a temperature without generating carbon scale to form a semifinished product including first and second driving ends and a handle interconnected between the first and second driving ends. The first and second driving ends of the wrench semifinished product are processed to form a combination wrench having a box end and an open end. | 02-25-2010 |
| 20110296954 | METHOD FOR SHAPING A HEXAGONAL TOOL - The method for shaping a hexagonal tool of the present invention includes the following steps: preparing a hexagonal rod having an axis and a bottom, which has a periphery; fixing the hexagonal rod on a lathe, the lathe having a clamp and a lathe tool, the hexagonal rod being clamped and rotated about the axis by the clamp, the lathe tool lathing the hexagonal rod in a single operation to form a neck portion on the hexagonal rod, a driving head being defined on the hexagonal rod between the neck portion and the bottom; and lathing a rounding edge around the periphery of the bottom by the lathe tool. As such, a hexagonal tool having a neck portion and a driving head is thus quickly formed. | 12-08-2011 |
| 20120210825 | Manufacturing Process of a Wheel Nut Wrench - In order to provide a manufacturing process for a wheel nut wrench in which strength of a nut socket portion is increased even though the process is facilitated under a situation where a tube made of carbon steel such as S45C is used as a material, the process includes the steps of: using a tube-shaped steel tube, forming a nut socket shell portion having a cross section of a hexagonal shape at an end portion thereof by cold pressing, pressing a sleeve made by a belt-shaped steel plate being bent and having a cross section of a hexagonal shape into the nut socket shell portion, and unifying a nut socket portion with the sleeve by plastic deforming. | 08-23-2012 |
| 20130145903 | TOOL BIT - A method of manufacturing a tool bit includes machining a working end into a piece of hexagonal bar stock. A shank adjacent the working end is machined, leaving a hexagonal drive portion adjacent the shank. The tool bit is heat treated, and a coating is applied to the working end, the shank, and the hexagonal drive portion of the tool bit to inhibit corrosion of the tool bit. At least a portion of the shank is polished to remove the coating from the portion of the shank. | 06-13-2013 |
| 20130167690 | Method for Marking a Tool - Disclosed is a method for marking a tool. The method includes the steps of providing a tool, executing heat treatment on the tool, providing a ground layer on the tool, printing the tool, and electroplating the tool. In the step of printing the tool, a paint layer is provided on the ground layer. The paint layer includes at least one identification unit. The identification unit includes at least one identification zone provided with paint, a background provided around the identification zone and clear of any paint, and a borderline provided around the background and provided with paint. In the step of electroplating the tool, a coat is provided on portions of the ground layer that are not covered by the identification zone and the borderline. There is sharp contrast of the coat against the paint layer. | 07-04-2013 |
| 20140260810 | Method for Marking a Tool - A method is disclosed for marking a tool. The includes the steps of forming a tool, making an indented mark in the tool, hardening the tool, coloring the tool to provide a color layer on the tool in and near the indented mark, clearing the tool of redundant colorant that overflows from the indented mark, black dying the tool to provide a black-died layer on the tool except the indented mark, and providing a transparent layer on the protection layer except the mark. The thickness of the transparent layer is larger than the thickness of the mark. | 09-18-2014 |
