#CMT# #/CMT# The nut (10) has a cylindrical connection element (18) arranged at a partially rotating flange (16) with a receiving opening (20). An internal thread (22) for accommodating an external thread (26) of a fixing screw (24) is formed in the opening. Diameter of the opening is smaller than diameter of the element. A set of torque transmission elements e.g. projection (30) and gripping element (32), is used for compensating torque that arises during setting, attaching and/or tightening of the fixing screw. #CMT#USE : #/CMT# Screw nut for providing screw connection of a component of a motor vehicle frame of a lorry (claimed). #CMT#ADVANTAGE : #/CMT# The set of torque transmission elements e.g. projection and gripping element, is used for compensating torque that arises during setting, attaching and/or tightening of the fixing screw, thus reducing assembling time of the nut without requiring additional tools, reducing cost of the nut, ensuring a safe connection of the components and ensuring high torque transmission, and hence reliably preventing slipping through the nut. The diameter of the opening is smaller than the diameter of the element, thus reducing weight of the nut. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a screw nut. 10 : Screw nut 16 : Rotating flange 18 : Cylindrical connection element 20 : Receiving opening 22 : Internal thread 24 : Fixing screw 26 : External thread 30 : Projection 32 : Gripping element. |
