Device for fastening bolts |
摘要 |
A device for fastening a bolt having a tip to be sheared therefrom comprises an outer socket engageable with a nut on the bolt, an inner socket engageable with the tip and retractably disposed in the outer socket, and stoppers provided between the inner socket and the outer socket for preventing the inner socket from retraction. When the tip is properly fitted into the inner socket, the stoppers are disengaged to permit the retraction of the inner socket and render the nut fittable in the outer socket.
