WIRING SCREEN DONUT 20X20 W/HDLS

A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.

A screen is physical divider intended to block an area from view or to block access.  Screens often provide protection or even filtration and may have holes or perforations allowing air or liquid flow.  A screen may also refer to a "touch screen" which provides a graphical user interface (a display device) which allows the user to interact with a computer or control by touching areas on the screen. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.
