Clamping screw 111820

with hexagonal headspannersteel

Wide range applicable bolt with nut, which allows independence in multiple ways: User defined clamping thickness, regardless of clamping a steel plate with 5 mm or 5 cm thickness. User defined screwing depth, regardless of screwing the bolt into the dowel 35 mm or into the threaded sleeve 100 mm. User defined hole diameter between 17 and 30 mm, the tightening of the conical shaped nut guarantees automatic centering without any tolerance in the middle of the hole. A shifting is not possible. Tightening without any special tool (fork wrench), hammer will be enough! No additional costs for adapter sleeves or washers. 1. Place clamping part over the anchoring point 2. Screw bolt into the anchoring ground 3. Tighten hexagonal nut by hand, in this way the nut will center the clamping part without tolerances. 4. Final tightening of the screw by simply turning it with second screw-in set. Because of the form of a screw spanner of the screw-in set also a conical flange nut can be tightened.
