An oval-shaped T-nut that is received within an oval receiver machined into the upholstered panel to be secured to a chair frame is provided. The oval shape of the T-nut prevents the oval-shaped T-nut from rotating when a screw is driven into the T-nut. Further, this eliminates the necessity of stapling the traditional plastic T-nut to the chair panel, thus saving time and money associated with the manufacture of an upholstered metal frame chair. In addition to the oval-shaped T-nut described herein, a novel U-shaped screw catch is also provided which cooperates with a barbed nylon or plastic push rivet to secure the upholstered chair panels to one another. Further, a method for connecting upholstered seat back panels to the tabs positioned on the back frame of a chair, utilizing the T-nut and the screw catch is disclosed.

The oval shape of the T-nut prevents the oval-shaped T-nut from rotating when a screw is driven into the T-nut. Further, this eliminates the necessity of stapling the traditional plastic T-nut to the chair panel, thus reducing materials and eliminating a manufacturing step, thus saving time and money associated with the manufacture of an upholstered metal frame chair. In addition to the oval-shaped T-nut described herein, a novel U-shaped screw catch is also provided which cooperates with a barbed nylon or plastic push rivet to secure the upholstered chair panels to one another.

An assembly includes a clip portion which includes a first flexible flange and a second flexible flange that each at least partially define a central retainer passage. A flexible hinge connects the clip portion to a structure. A tab is located adjacent an opposite end of the clip portion from the flexible hinge.

An operating nut can include a body and a digital identification tag secured to the body, at least one of the body and the digital identification tag defining an outer surface of the operating nut. The body can define a central bore defining an axis and can include a working portion defining an end surface and a plurality of side surfaces defining a polygonal shape in a cross-sectional plane orthogonal to the axis; and a flange portion extending outward from the working portion in a radial direction with respect to an axis of the operating nut, the flange portion defining a first end surface and a second end surface, the central bore extending through each of the working portion and the flange portion.

Provided herein is a household appliance with at least one pedestal comprising a threaded rod which can be screwed into a corresponding threaded hole in a base of the household appliance in a longitudinal direction in order to reach a desired effective height of the pedestal. A snap nut made of a resilient material is provided having a threaded bore with a diameter and a thread fitting to the threaded rod so that the snap nut can be screwed along the longitudinal extension of the threaded rod, the snap nut further comprising a slot having a width that is less than the diameter of the bore and which defines a lateral opening of the bore wherein the width of the slot and the resiliency of the material allows the snap nut to be snapped from the side onto the threaded rod.

A method of using an operating nut includes engaging a tool with the operating nut of a device, the operating nut including a digital identification tag and the tool including a digital identification tag reader, placing the digital identification tag reader within a read range of the digital identification tag, and reading the digital identification tag with the digital identification tag reader to receive data of the device.
