Abstract:
PCT No. PCT/SE95/00362 Sec. 371 Date Mar. 10, 1997 Sec. 102(e) Date Mar. 10, 1997 PCT Filed Apr. 5, 1995 PCT Pub. No. WO95/29343 PCT Pub. Date Nov. 2, 1995A rotatable device, such as a screw, a bolt, etc., comprises a cylindrical clip (4) inserted into a bore (3) in the head of the rotatable device. The clip (4) is compressed to a certain extent when inserted into the bore in order to confer to the clip a springing effect on the wall of the bore. Further, the clip comprises a socket for the insertion of a suitable turning key. When turning the key, only a maximum torque is transferable to the rotatable device. If this value is exceeded, the clip starts sliding in the bore.
