Definitions

  • the invention deals with the problem of simply and securely fastening a component that has an external thread in a bore that does not have a matching internal thread.
  • the object of the invention is to provide an alternative way of attaching grease nipples and other threaded components.
  • an aid in the form of a screw with a self-tapping thread and a head that forms a tool handle on its outer circumference the aid being characterized in that the head has an axial internally threaded bore.
  • the internal thread hole matches the external thread of the component to be fastened. This makes it possible to first screw the screw with its self-tapping thread into the hole and tighten it firmly so that the screw is held securely in the hole, and then insert the component to be fastened, such as the grease nipple, into the internally threaded hole in the head of the screw to fasten.
  • the component to be fastened such as the grease nipple
  • the head of the screw preferably a hexagonal head, forming the tool handle, for example in the form of wrench flats, has a height which is at least 60% of the largest diameter of the self-tapping thread.
  • the height of the head is greater than the largest diameter of the self-tapping thread.
  • the self-tapping thread and the internal thread of the screw may be complementary to each other in the sense that both threads have the same diameter, pitch and pitch, but the internal thread need not have the taper of the self-tapping thread.
  • the aid according to the invention as a type of thread former, with which a thread is created in the bore, into which a component with the same self-tapping thread, for example a grease nipple, can then be screwed.
  • the self-forming thread and the internal thread differ in the thread standard.
  • the thread section that forms the self-forming thread can optionally have a greater wall thickness than the self-forming thread section of a conventional grease nipple, so that greater mechanical stability is achieved.
  • the tool according to the invention can also be used to connect threaded parts that have non-compatible Ge thread standards.
  • an aid according to the invention with a metric internal thread can also be screwed into a hole with an inch thread, so that a component with a metric external thread can then be fastened in a hole with an inch internal thread.
  • a component with an inch external thread can also be fastened in a hole with a metric internal thread.
  • FIG. 1 shows a half-cut side view of an aid according to the invention
  • FIG. 2 shows the aid according to FIG. 1 in plan view
  • Figures 3 and 4 different stages in the attachment of the tool in a bore of a base component
  • Fig. 5 shows a grease nipple which is attached to the base component with the aid according to the invention; 6 shows a section through the base component after removal of the auxiliary means; and
  • FIG. 1 and 2 show a fastening aid in the form of a screw 10 with a self-tapping thread 12 and a head 14.
  • the head 14 is a hexagonal head and thus forms six wrench flats 16 on its outer circumference.
  • the head 14 also has an axial internally threaded bore 18 , which transitions via a conical bore section 20 into a smooth axial bore 22 in the threaded section that forms the self-tapping thread 18 .
  • the height of the head 14 and thus also the height of the wrench flats 16 is greater than the maximum diameter of the self-tapping thread 12.
  • the internally threaded bore 18 has in the example shown a metric thread with the same diameter, the same pitch and the same pitch as the self-tapping thread 12.
  • FIG. 3 shows the screw 10 in a state in which the end of its self-tapping thread is attached to the opening of a bore 24 in a base component 26 .
  • the screw 10 has been lightly tapped into the bore 24 with a hammer so that it does not need to be held in position by hand.
  • the screw is then screwed deeper into the bore 24 with a wrench or cleat, with the self-tapping thread 12 cutting into the wall of the bore and creating an internal thread there.
  • FIG. 5 shows the screw 10 in the fully screwed-in state.
  • a grease nipple 28 has been screwed into the internally threaded bore 18, which in turn has a flat hexagonal head 30 and a self-tapping thread 32, which is identical in shape to the self-tapping thread of the screw 10.
  • Fig. 6 shows the bore 24 of the base component 26 with a conical internal thread 34, which was cut into the peripheral wall of the bore by the self-tapping thread 12 and, after removing the screw 10, also allows the grease nipple 28 to be screwed directly into the bore 24, as in 7 is shown.
