THREAD ENGAGEMENT RELEASE CONFIRMING MECHANISM FOR REMOTE BOLT

摘要

PROBLEM TO BE SOLVED: To provide a thread engagement release confirming mechanism for a remote bolt capable of performing the tread engagement release confirmation works of the remote bolt without changing an impact wrench to an dedicated threading engagement release confirmation tool and shortening the working time by the rational works. SOLUTION: A wrench socket 20 fitted to the head part of the remote bolt, rotated by the impact wrench, and rotating the remote bolt is provided with a friction lock mechanism 23 facing to the fitting recess part 21 and comprising a ball plunge 40 pressing and energizing a steel ball 43 in the tip by a spring 42. It is so constituted that the friction force by the pressing allows the wrench socket 20 to support the remote bolt 30.
