The anchor comprises an anchor body having a first body portion engageable to the base plate and a second body portion extendable into the substrate to be drilled. The second body portion comprises first and second cylindrical sections. The first cylindrical section is disposed in axial alignment with the first body portion and the second cylindrical section is formed to vary between a first postion in axial alignment with respect to the first body portion and a second position eccentric with respect to said first body portion. The first and second cylindrical sections are adapted to cooperatiely engage the substrate when the second cylindrical section is disposed in the second position to maintain the anchor body in place with respect to the substrate.Field of SearchHelical anchorMates with mandrel thread With wedge-shaped expander Made up of plural expansible segments or sections Identical segments And means to captively retain expander Stepped expander Sleeve having external gripping means Circumferential rib And longitudinal rib Relatively sliding wedge surfaces Wedge received in transverse slot in holding device or anchor Double-faced wedge Having wedge retainer means Wedge surfaces act in single lateral direction Including discrete activating means for wedge Member anchors bolt in substructure with threaded portion exposed (e.g., stud bolt) Securing means pivotable about axis transverse to fastener axis, e.g., toggle bolt, etc. And discrete manual actuating means Securing means rotatable about fastener element or rotatably engageable by tool-rotatable headed fastener element HEADED FASTENER ELEMENT WITH NUT, WASHER, SECURING MEANS OR CAP Retainer ring | |
