Abstract
In accordance with one or more embodiments of the invention, nut restrainers, centering tools, and methods of use are presented, particularly as applied to high strength bolted connections. Nut restrainers may have an interior profile including a circular profile section and a regular hexagonal profile section, a nut inserted into the nut restrainer may have lateral freedom of movement, and the nut restrainer may have a top plane with one or more centering protrusions. A centering tool for positioning a nut restrainer may have a non-circular head section, a cylindrical positioning section, a threaded section, and a cylindrical restrainer positioning section; a method of positioning a nut restrainer coaxial with a bolt hole using the centering tool.

A nut restrainer configured to receive a nut, the nut restrainer comprising:
- a shaped portion configured and structured with an interior profile and a top plane;
- the interior profile is configured and structured with a profile section to receive the nut;
- the interior profile is further configured and structured to restrain the nut with a limited freedom of movement in at least one lateral direction;
- and
- at least one centering protrusion configured and structured to bend so as not to impede receiving a tip of a bolt,
- wherein the nut restrainer is configured to confine the nut therein;
- wherein the nut restrainer is configured to be affixed to a substrate plate that has a bolt hole;
- wherein the nut restrainer is configured to be affixed to the substrate plate over the bolt hole and receive subsequent installation of a bolt with access from only one side of the substrate plate;
- and
- wherein the nut restrainer is configured to be affixed to the substrate plate via welding.
