Title:
CONFIRMING TOOL FOR BOLTING
Document Type and Number:
Japanese Patent JP3312196
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily confirm the fastening of a bolt and to detect even its looseness by attaching a cap to detachably fit on a polygonal bolt head or a nut and an indicator set with the cap in one or another body.
SOLUTION: A cap 5 has a recessed part to detachably fit on a polygonal bolt head, and many grooves 6 to detachably threadedly engaged with an indicator 7 are formed on the outer periphery of the cap 5. The indicator 7 is composed of a ring-shaped attaching part 9 having many grooves 8 formed on its inner periphery and a needle 10 provided continuously in a body with the attaching part 9, and the groove 8 can be externally engaged in the groove 6. The cap 5 and the indicator 7 are conveniently connected with a string-shaped thing 11. The bolt can therefore be positioned at any stopped position so that the needle 10 may always point to a fixed direction. Thus the fastening of the bolt can easily be confirmed, and the forgotten tasting of the bolt can be prevented, and even the looseness of the bolt can be detected.
