Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts.
Nuts are most commonly hexagonal in shape. It is important to use the correct sized spanners to avoid, ‘rounding off,’ the nut. Otherwise, if using an adjustable spanner you must ensure it is full tightened over the flat faces. Other specialized shapes exist for certain needs, such as wingnuts for finger adjustment and captive nuts (eg cage nuts) for hard to reach areas.
UNITS OF MEASUREMENT FOR THREAD TYPES
UNIFIED THREAD STANDARDS
The basic American standards for fastening screw threads as agreed upon by standard bodies of Canada, the United Kingdom, and the United States. They are a complete and integrated system of threads for fastening purposes. Their outstanding characteristic is general interchangeability of threads achieved through the standardization of thread form, diameter-pitch combinations, and limits of size
Unified National Coarse (UNC) is a thread form with a 60 degree flank angle rounded roots and flat crests. For a given diameter it has a larger thread pitch than an equivalent diameter UNF thread. The unified thread is based on inch sizes and was first standardised in 1948 unifying the Whitworth and American standard thread forms
Unified National Extra Fine (UNEF) is a Unified thread form with a very fine (small) pitch and are typically used on instruments and parts requiring a fine adjustment.
Unified National Fine (UNF) is a thread form with a 60 degree flank angle, rounded roots and flat crests. For a given diameter it has a smaller thread pitch than an equivalent diameter UNC thread.
Unified National (UN) thread form with a rounded root contour, applies only to external threads. (The UN thread form has a flat, or optionally, a rounded root contour.) The majority of fasteners with a Unified thread form (UNC UNF) have a rounded root contour.
