Commonly used when measuring the flat surfaces of a hex drive, such as a hex nut. AFF above finished floor A dimension that establishes a distance away from the finished floor. Example would be the top of a coffee table to the shag of the carpet, not where the bottom of the tables feet dig in. AISI: American Iron and Steel Institute

A self-aligning nut, also known as a spherical nut [2] or leveling nut, is a type of nut used in applications where the fastener is not perpendicular to the surface to which the nut anchors. A flange nut is used inside a specially shaped dished-out washer. The device is commonly used in the aerospace industry.
They may either have a Phillips flat head or a slotted hex washer head. Nominal (thread) sizes range from 0.1875 to 0.375 in (4.763 to 9.525 mm) and lengths from 1.25 to 5 in (32 to 127 mm). Typically an installer uses a hammer drill to make a pilot hole for each concrete screw and a powered impact driver to drive the screw. The drill hole ...

The standard (size) tolerances are divided into two categories: hole and shaft. They are labelled with a letter (capitals for holes and lowercase for shafts) and a number. For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). H7/h6 is a very common standard tolerance which gives a tight fit.
A G-nut, or G-style nut, is shaped like a "G" and clips to the edge of a sheet metal object. It is different from all of the other types in that it is meant to clip over a small flange on the edge of the sheet metal. The threads are from an integrated nut that has a special boss to sit in a hole in the sheet metal. [2]
