#CMT# #/CMT# The element has sequential carriers (2) provided at a head (10) of the element, where the carriers extend axially and circumferentially and screwing process is enabled in tightening rotational direction (100). The carriers are designed such that a screw connection element turning tool e.g. adapter, slides against the tightening rotational direction of the carriers. Engagement surfaces (2b) of the circumferentially spaced carriers are defined in the same direction. The head of the element is designed conically. #CMT# : #/CMT# An independent claim is also included for a tool. #CMT#USE : #/CMT# Irreversible screw connection element e.g. screw or nut. #CMT#ADVANTAGE : #/CMT# The carriers are designed such that the screw connection element turning tool slides against the tightening rotational direction of the carriers, so that power transmission is prevented by the tool on the screw connection element against the tightening rotational direction while reducing cost and material required for the screw connection element. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an irreversible screw connection element. 2 : Sequential carriers 2a : Flat running bevels 2b : Engagement surfaces of carriers 10 : Head 100 : Tightening rotational direction. |
