SS Hex Weld Nuts DIN 929 
A weld nut is a special type of nut specifically designed to be welded to another object. There are various types for different applications.
These nuts are very similar to standard hex nuts, but have a locating boss and welding projections. The bosses also keep weld spatter out of the threads.
Hex weld nuts are a six-sided, internally threaded fastener with three triangular weldable projections on the top surface of every other corner of the fastener. The threaded hoe runs through the centre and has a pilot for the entire circumference of the opening which extends above the top surface of the nut and the above projections. The remainder of the top surface of the nut is flat.

Square Nuts
A square nut is a four-sided nut.
Compared to standard hex nuts, square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening. They are also much less likely to become rounded-off after repeated loosening/tightening cycles.
Square nuts can be tightened with pliers or a wrench, making them ideal for use in blind locations. The user can tighten and loosen a square shaped fastener without having it in sight, as long as a sturdy grip can be obtained on two opposing sides of the nut or bolt head.

USES
The wing nut should be used in a setting where the fastener that is to be used needs to be opened and fastened with ease and in a frequent manner. A good example of this is when you need to fasten a lid on a particular type of machinery, but in such a manner that you will still have easy access to it when you need to.
Home and office furniture manufacturers make frequent use of wing nuts. Beneath almost every modern desk chair, a modified wing nut serves to control the tension on the chair. Wing nuts also are used to allow the rapid exchange of interchangeable parts, such as the heads of mops or other tools and cleaning implements. Microphone or music stands also may use them to put pressure on pipes to allow rapid raising or lowering while preserving structural stability.
When should they not be used?
There are a few instances where a wing nut should not be used for fastening, mostly due to the limitations that it has in terms of function. A good example of this is when the product being tightened will be subject to a lot of vibration. There are times when such movements can loosen the wing nut. This is especially so when they are not fastened properly, or when low quality ones are used for this purpose.
In addition to that, you should also be wary of using a wing nut to fasten an item when you want it to be very tight. A good example of this is when you need to fasten something in such a manner that it will end up being waterproof. The fact that a wing nut is meant to be easily opened means that if you use it in such a setting, it might not work as well as other types of fasteners.
Thumb Nuts
The Thumb Nut is a type of nut meant to be tightened and loosened by hand without tools.
It has a knurled head to provide extra grip and prevent slippage when tightening and loosening. The head diameter of the nut is large for ease of use and also provides a high degree of rotational accuracy.
These are widely used in various applications where frequent access, adjustment, or disassembly is required, such as in the field of electronics, computer hardware, automotive, and machinery. Their convenient design enables users to make quick and tool-free adjustments, making them especially valuable in situations where efficiency and convenience are crucial.
