Title:
ねじ山のないナットアンカーで使用するための高性能ねじ山転造ねじ／ボルト
Document Type and Number:
Japanese Patent JP6581979
Kind Code:
B2
Abstract:
The present invention provides a screw/bolt thread profile geometry that is particularly suited to forming a mating nut thread when the screw is inserted in to a plain diameter hole, in the anchor and rotated in a manner by which the thread helix angle will cause the relative axial forward movement, of the screw/bolt, into the anchor. This rotation and relative axial movement will be the prime mover in developing the nut thread that has mating contact with the screw/bolt thread.
