摘要 |
A power-driven insertion tool for a helically coiled wire insert of the type used for tapped holes in parent material that is generally softer than a fastener being screwed into the tapped hole, whereby a mandrel having a threaded lead portion and a pivotal pawl inserted in a groove below the threaded portion so that the pawl engages a recess of the insert, in order that the insert may be screwed into the tapped hole. A sleeve, concentric to the threaded mandrel, maintains the insert's helix angle for a smooth transition into the tapped hole. An adjusting nut adjusts the depth to which an insert may be installed and whereby a free spinning bearing contacts the parent material and automatically reverses the torque of the tool. |
