Definitions
- the preamble of claim 1 specified type alternatively form so that a simple and reliable mounting of components on a solid anchoring ground without the use of dowels or other tools is possible.
- the invention is also based on the object, a thread-forming screw according to the preamble of claim 1 in such a way that a simple and reliable fastening of components on a solid anchoring ground without pre-drilling is possible.
- the outer diameter of the second thread turn is greater than the outer diameter of the opposite of the setting direction of the second thread following third thread turn.
- the distance of the first thread turn to the second thread turn is greater than the distance of the second thread turn to the third thread turn. th thread and preferably also greater than the distance of the third thread to the first thread.
- the at least three threads in interaction with the different distances between the threads to each other less stress in the anchoring ground.
- the distance between adjoining bores in the anchoring ground can thus be reduced.
- the number of holes on a given area unit can thus be increased advantageously.
- each thread has a constant outer diameter over the length of the shaft.
- each thread is formed as a pointed thread.
- the invention also relates to a, in a bore or in a non-predrilled anchoring base, preferably with or exclusively made of wood, screwed, thread-forming screw, which is designed according to one of claims 1 to 12.
- the universal screw 10 has three threads 20, 22 and 24, which are formed parallel to each other and extending helically over the length of the shaft 16.
- the outer diameter dl of the first thread 20 is greater than the outer diameter d2 and d3 of the opposite of the setting direction 26 of the first thread 20 following thread 22 and 24.
