Abstract: A screw with a recessed head (3) has a crossing recess (4) formed in a top of the head and consisting of a central region (5) and four grooves (6) extending radially from the central region. Each groove is tapered to reduce width towards an outer conical bottom (9), which defines the groove together with opposite side walls (7, 8) transmitting torque. The bottom connecting outer edges of the side walls has a width ‘A’ larger than width ‘a’ in the widely used standard recesses of the same length ‘M’. The side walls have a radial length ‘B’ smaller than ‘A’, and distance ‘C’ between the intersections of two side walls of different grooves is equal to or larger than the product of 1.5 and ‘A’. One side wall (7) lies in a flat plane in parallel with the screw's axis, and is located forward in a tightening direction of the screw. The conical bottom (9) slanted 5° relative to the axis provides a conical sticking surface. The crossing recess simply modified will transmit a stronger torque and affording a larger sticking area resistant to a stronger thrust, when driven with a driver bit matching the recess and provided here.

Abstract: A recessed screw has a recess formed in the head of screw, with the recess being defined as a superimposition of two equilaterally-triangular recesses each having vertices shaped arcuate and arranged coaxially with a phase shift of 60.degree. around the screw axis. The recess thus has alternating six grooves and six driven vanes having side walls extending parallel with the axis, and an inner ridge of vane is a conically curved sticking wall inwardly slanted towards a bottom of the recess. A cross-sectional area of groove is larger than that of each vane. A driver bit has six driving vanes in conformity with the grooves and six valleys each interposed between the adjacent driving vanes and corresponding to the driven vanes in the recess, such that a biting action appears between the recess and bit, the driving vanes can be strengthened, and any conventional bit for Torx screws can be used with the recessed screw.

Abstract translation: 凹入的螺钉具有形成在螺钉头部中的凹部，凹部被定义为两个平均三角形的凹部的叠加，每个具有弓形的顶点，并且围绕螺杆轴线以相位相差60°同轴布置。 因此，凹槽具有交替的六个凹槽和六个带有与轴线平行延伸的侧壁的驱动叶片，并且叶片的内脊是向凹入部的底部向内倾斜的锥形弯曲的粘贴壁。 槽的横截面积大于每个叶片的横截面面积。 驾驶员钻头具有六个驱动叶片，其与凹槽和六个凹槽相配合，每个凹槽各自插入在相邻的驱动叶片之间并且对应于凹部中的从动叶片，使得在凹部和钻头之间出现咬合动作，可以增强驱动叶片 ，并且用于Torx螺钉的任何常规钻头可以与凹入的螺钉一起使用。

Abstract: A method and apparatus for manufacturing anchor bolts to be fixed on concrete structures, with the method comprising preliminarily heading a steel rod to form at an upper end thereof, a head having a tapered surface gradually tapering downwardly from the upper end and decreasing in diameter; forming the mail screw at the other end of rod by thread-rolling and simultaneously rolling a part adjacent to the head to form a rod-portion of a reduced diameter by gradually displacing a surface layer of the rod-portion inwardly and outwardly to give rise to an inner and outer transient swells respectively forming a stopper a tapered portion merging into the tapered surface of head; and loosely fitting and expansible sleeve on the rod-portion of reduced diameter, with the sleeve being made by die-cutting and bending a metal plate into a cylindrical shape of an outer diameter substantially equal to outer diameter of the screw. The apparatus includes a header forming the preliminary head, and a pair of rolling die assemblies each comprising a thread-rolling die to form the screw, a neck-rolling die combined therewith by a spacer and adapted to form the rod-portion of reduced diameter.

Abstract: A peel type blind rivet (1) has a rivet body (2) composed of a cylindrical part (3) and a flange-shaped head (4) formed integral with one end of the part, and a mandrel (5) composed of a body (6) for insertion in the part and an enlarged head (7) formed at one end of the body. Radial blades (9) are formed integral with a lower surface (8) of the mandrel head such that the other open end (14) of part (3) will be cut into radially protruding split feet (14a) when the mandrel body (4) is pulled back. The mandrel head (7) is of a maximum diameter (D) greater than an outer diameter (d) of the cylindrical part (3). The lower surface (8) increases its diameter gradually and upwards from the mandrel body (6) towards a rim (7a) of the mandrel head having the maximum diameter. Each blade (9) is of a V shape protruding downwards from the lower surface such that a cutting edge (10) of each blade extends upwards and obliquely from the mandrel body towards the rim. A circumcircle of outer ends (10a) of the cutting edges is of a diameter (d1) equal to or slightly greater than the outer diameter (d), so that the blades can surely and uniformly sever the rivet body open end so as to provide a reliable strong fastening force.

Abstract: A concrete anchor has an anchor body 21, which is a rod-shaped member 22 having a male thread 23 and a striking head 24, both formed at one end of the member. This rod-shaped member 22 further has at its another end a cylindrical portion 25 so that slots 26 extend axially from an open end of the portion so as to provide expandible feet 27. Saw-toothed scratching tips 28 are formed to be acute ends of the expandible feet. A tapered plug 31 which is inserted in the cylindrical portion 25 has an annular recess 34 and a retaining shoulder 36, both formed between a large diameter portion and a root 35 of the tapered plug, with the annular recess providing a cavity to receive concrete scrapings, so that an impact applied to the striking head can provide a strong and effective retention force for the concrete anchor, and any cracks which may be produced around a hole holding the fixed anchor does not impair the retention force.

Abstract: A method of making an elongated mandrel having an end integral with a drill section, with the method including the steps of subjecting a single columnar piece of material to the heading process so as to make a blank N composed of the mandrel, a short stem having one end integral with the end of the mandrel and having a diameter D greater than a diameter of the mandrel, and a flange formed integral with the other end of the stem. The short stem is then cold forged to produce the drill section having end edges (7a) and (7b) facing the flange, and, subsequently, the drill section is trimmed so as to remove the flange together with a scrap resulting from the cold forging of the stem, in such a manner that the mandrel having the integral drill section can be mass produced from the single piece of raw material, efficiently at a reduced cost.
