PCT No. PCT/SE95/01204 Sec. 371 Date Jun. 30, 1997 Sec. 102(e) Date Jun. 30, 1997 PCT Filed Oct. 16, 1995 PCT Pub. No. WO96/12114 PCT Pub. Date Apr. 25, 1996The invention relates to a fastening element with a torque-limiting function, comprising on the one hand a fastening member (2, 2') with working threads (4), that is to say threads which are active for the fastening function of the element, and on the other hand a gripping member (3, 3') which is arranged so as to be capable of being turned with the aid of a spanner, wrench, screwdriver or other tool for attaching the fastening element (1, 1') and connected or connectable to the fastening member (2, 2') via torque-transmitting threaded connection (5, 6/17, 18) with sufficient strength in order to be capable of transmitting to the fastening member torque of the size for which the fastening element is intended, and in which the gripping member is arranged to be unscrewed and turned relative to the fastening member, on attachment of the fastening element, only when the torque exceeds a given predetermined torque. The threads (5, 6/17, 18) in the torque-transmitting threaded connection are threaded in the opposite direction compound with the working threads (4). |
