摘要： A screw includes a head having a top face and a conical bottom surface, a shank, and thread convolutions. A chip guiding channel is recessedly formed on the conical bottom surface. On the conical bottom surface are spirally disposed a cutting portion which has a plurality cutting units sequentially arranged in a spiral manner, thereby allowing the chip guiding channel to be surrounded by the cutting units along a spiral track. The spiral arrangement of the cutting units assists the head in cutting fibers of a workpiece which are wound around the head into small chips in a continuous and spiral severing manner to reduce drilling torque and resistance, and the spirally-defined chip guiding channel also facilitates a smooth removal of the chips, thereby allowing the head to fit level with a top surface of the workpiece and increasing a fastening effect.

摘要： A self-drilling screw includes a leading section having a drill body and opposite discharge grooves formed on the drill body. The drill body and the discharge grooves meet at cutting edges. On the drill body are formed two blade portions connected to the cutting edges and tapering at respective second tips. The blade portion has a second included angle of not more than 50 degrees. Between the blade portions is formed a drilling portion terminating at a first tip and having a first included angle of not more than 60 degrees. Two opposite concave surfaces each extend from the drilling portion to each blade portion. The first tip and the second tips are situated at different places. Accordingly, the end of the leading section presents a shape of a curved bow riser to cut quickly and help quick removal of chips, thereby decreasing resistance and preventing the cracking problem.

摘要： A wood screw structure comprises a screw head section, a rod section, a first screw thread and a plurality of crushing rib units. The rod section is sequentially integrally formed from the screw head section and comprises a first rod portion connecting the screw head section, a second rod portion, a third rod portion, and a tapered portion extending and tapering outwardly from the third rod portion. The first screw thread is disposed spirally and is protruded on an outer peripheral surface of the tapered portion, the second rod portion and the third rod portion. The crushing rib units are disposed spirally and protruded around the outer peripheral surface of the third rod portion and the tapered portion, and each of the crushing rib units includes a plurality of crushers protrudingly disposed on a rib body. A first discharge gap is formed between the crushers.

摘要： A joining method is a method of joining a plate set composed by a plurality of stacked plate members including a first plate member and a second plate member by using a tapping screw. When the tapping screw is advanced into the plate set while the tapping screw is rotated in a state of applying a pressure onto the plate set so as to form through-holes in the first plate member and the second plate member, a first pressure applied onto the tapping screw is reduced down to a second pressure at the time when the tapping screw penetrates the first plate member.

摘要： A self-driving masonry anchor that includes ahead configured to receive a driving bit, a threaded section extending from the bottom of the head, a drilling section following the threaded section, and a drill tip at the end of the drilling section. The threaded section includes alternating high and low threads. The high threads include notches or serrations. The low threads are double low threads such that there are two low threads between each high thread. The drilling section includes at least two flutes for the removal of debris. The drill tip includes an abrasive material which is different than the material of the drilling section such that the drill tip and drill section predrill a hole in a masonry material for the threaded section, the threaded section fastening to the masonry material.

摘要： A threaded fastener includes an elongated body having a first end and a second end, a first portion comprising a first helical thread, with the first helical thread including a crest, a root, and flank portions, and a second, tapered portion including a second helical thread. The second helical thread includes a crest, a root, a leading flank portion, and trailing flank portion, with the leading flank portion positioned closer to the second end of the elongated body than the trailing flank portion. A thread angle of the second helical thread is larger than a thread angle of the first helical thread, and the root of the second helical thread includes a root apex formed by the intersection of the trailing flank portion and the leading flank portion.
