A cold formed anchor for use in an insulated cavity wall includes a unitary body formed with a driver portion and having large and small diameter portions. The driver portion may be formed with structure for connecting a veneer tie to the anchor. A method of making the cold formed anchor includes cold forming a driver portion and a reduced diameter portion from a blank.

A method of welding a weld stud to a workpiece and of checking the strength of the welded joint includes the steps of providing a tool, a workpiece, and a weld stud, the weld stud including a shank and a polygonal shaped head; welding the weld stud onto the workpiece; applying the tool to the polygonal shaped head section of the stud; applying a predetermined test torque to the weld stud with the tool; and checking the welded joint for satisfactory acceptance of the test torque.

A steel wire for non-heat treated machine parts, the steel wire contains, based on % by mass: C: from 0.20 to 0.40%, Si: from 0.05 to 0.50%, Mn: from 0.50 to 2.00%, Al: from 0.005 to 0.050%, and the balance being Fe and impurities, in which the microstructure contains bainite of (35[C %]+50)% or more, and when the diameter is defined as D, the average aspect ratio of a bainite grain at a depth of 50 m in the L cross section is defined as AR, and the average grain size of a bainite grain at a depth of 50 M in the C cross section is defined as GD, AR is 1.4 or more, (AR)/(the average aspect ratio of a bainite grain at a depth of 0.25D in the L cross section) is 1.1 or more, GD is (15/AR) m or less, and (GD)/(the average grain size of a bainite grain at a depth of 0.25D in the C cross section) is less than 1.0.

One aspect is an apparatus including an additively manufactured first component and a captive nut contained within the first component for interconnecting the first component to a second component. Another aspect is an apparatus including a first additively manufactured component having a hole and a second additively manufactured component having a socket. The apparatus further includes a pin having a head engaging a surface of the first component and a shaft extending from the head through the hole in the first component and into the socket of the second component. Another aspect is an apparatus including first and second panels. The apparatus also includes a bolt having a head and a shaft extending from the head and a nut located at a distal end of the shaft. The first and seconds panels may be sandwiched between the bolt and nut to interconnect the first and second panels.

A connection element consists of a longitudinally oriented support structure that is at least partially hollow and a sensor unit that is arranged in the inside of the support structure, is connected to a signal transmission device, and is non-positively connected to the support structure. The required force for the non-positive connection is produced by internal stresses after a plastic deformation of the support structure during a joining process of the support structure and the sensor unit. A method for manufacturing a connection element consisting of a support structure that is at least partially hollow and a sensor unit includes positioning the sensor unit in a region of the support structure and, using radially movable tool segments, exerting a force on the support structure in the radial direction and at the same time reducing the periphery of the support structure in the region in which the sensor unit is positioned.
