DE7431974U - Screwdriver for socket head cap screws - Google Patents

Description

date

The innovation relates to a tool with the help of which "cylinder screws with hexagon socket ¹ * Ä.B according to DIN 912, 6912 etc. can be tightened and loosened, whereby the lever itself remains on the screw head and when the screw is tightened by repositioning , in the hexagon socket of the screw head, can assume different angular positions »There are tension levers and clamping levers that also allow such angular positions in the tightened state, but these components all have the disadvantage that the screw bolts are part of the complete tension lever and therefore for Every size, especially for every length and every material of the screw bolt, a complete component, consisting of a clamping lever and screw bolt, must be placed on the bearing. On the other hand, the technical effort for clamping levers, which are only operated a little, is much too high ·

The innovation is intended to remedy this deficiency. As already mentioned at the beginning, "cylinder head screws with hexagon socket" are part of the lever according to DIN. For example, the DIN screw only needs to be changed for the same lever in order to obtain a different clamping lever in terms of material and screw length, or, in other words, every built-in cylinder screw with hexagon socket ¹¹ can be converted into a soann lever or clamping lever in this way Above all, this option results in significant space and cost savings in warehousing.
