Abstract
A fastener and plate assembly includes a plate including a hole having a first threaded lobe with a first axis and a second threaded lobe with a second axis. The second axis is offset relative to the first axis. The assembly also includes a threaded fastener received in one of the first threaded lobe and the second threaded lobe of the hole to install the threaded fastener in one of a first orientation and a second orientation, respectively.
Claims17
A fastener and plate assembly comprising:
- a plate including a hole having a first threaded lobe with a first axis and a second threaded lobe with a second axis, wherein the second axis is offset relative to the first axis;
- and
- a threaded fastener received in one of the first threaded lobe and the second threaded lobe of the hole to install the threaded fastener in one of a first orientation and the second orientation, respectively.
A fastener and plate assembly comprising:
- a plate including a hole having a first threaded lobe with a first axis, a second threaded lobe with a second axis, a third threaded lobe with a third axis, wherein the second axis is offset relative to the first axis, and the third axis is offset relative to the first axis;
- and
- a threaded fastener received in one of the first threaded lobe, the second threaded lobe and the third threaded lobe of the hole, wherein threads of the threaded fastener engage threads of one of the first threaded lobe, the second threaded lobe or the third threaded lobe for at least 180° around a central axis of the threaded fastener to install the threaded fastener in one of a first orientation, s second orientation, and a third orientation, respectively.
A method of forming a hole in a plate, the method comprising the steps of:
- forming a first base hole through a thickness of a plate, the first base hole having a first axis;
- forming a second base hole through the thickness of the plate that partially overlaps with the first base hole, wherein the second base hole has a second axis that is offset relative to the first axis;
- forming threads in the plate around the first base hole;
- forming threads in the plate around the second base hole;
- and
- receiving a threaded fastener in one of the first base hole and the second base hole such that the threads of the threaded fastener engage the threads of the one of the first base hole and the second base hole to install the threaded fastener in one of a first orientation and a second orientation, respectively.
