Abstract
By electrically fusing a pin between the outer elements of a box hinge, and thereafter performing the hardening step, stresses which tend to cause instrument failures after a period of use are eliminated. Even if the pin fractures during use, the fact that it is fused to the outer elements of the box hinge prevents broken-off parts of the pin from falling out of the instrument.
