摘要：A staple-nail fastener for nailing a ceiling support strip to a panel of wallboard which consists of a length of relatively hard steel wire bent into "U" shape to form long and short legs approximately parallel to one another, the long leg being approximately one-quarter inch to approximately three-eighths of an inch longer than the short leg. The long leg is chamfered to a sharp point, while the short leg prents a tip which is less sharp so that when the fastener is hammered into the strip the long leg readily penetrates the strip while the short leg resists penetration, rving as a fulcrum for the long leg to impart broadwi swinging movement thereto so that, as the long leg continues its penetrating movement, it regionally compress the wallboard in the direction of the strip, until the short leg assumes a final position in which it lies flatly and snugly against the strip. In its preferred embodiment, the staple-nail is approximately one and one-half inch long and approximately one-half inch in average width.
