b) J-Nut

A J-nut is referred to as that nut which is found clipping into the edge of the sheet metal. This type of nut is named in such a way as it is shaped in the shape of an alphabet J wherein the thread is found to be at the longer side of the “J”. The short retaining leg is not allowed in order to float more, this is found being responsible for the misalignment whereas the nut is found to be free to un-clip the sheet metal as well.

c) S-Nut

A S-nut is also termed as a S-style nut which is named due to the exterior shape of the nut like the alphabet S. These are the types of nuts which are particularly designed in order to clip at the edge of a any metal sheet metal. These are known as threads which are found being provided by an integrated nut only.

d) Square Style Nut

A square style clip-on nut is referred to as that which is not suitable for clipping at the edge of the sheet metal although the edges of a square hole or slot. It is also termed as a square nut which has a sheet metal retainer which protrudes down the two sides of the nut. These legs are found being formed in order to have the lips which usually grab onto the sheet metal object. Until the nut is tightened, you will be able to observe it floating in the hole or at the slot only when the nut is found being fully tightened as it presses the lips which are present at the retainer outside and thus anchors itself in its required place.

e) U-Nut

A U-nut is referred to as that technical instrument which has same properties as that of a J-nut except their both the legs which seem to be of the same length. This is what is helpful in retaining the clip which seems to be usually formed on the leg excluding the threads. This is responsible for helping the nut into the screw down position. The threads which are found in these types of nuts are technically the same as those which are present in the speed nut style which might get integrated along with the nut or might have found other major portion which is usually known to be tapped.

There are the standard as well as the wide-panel versions which are commonly known to us in the U- nut type. The standard version is found having a solid hinge section, whereas the wide-panel version is found having a longer hinge along with the centre section cut-away to let it help more for the easier installation.

6. Coupling Nut: ( Types of Nuts )

A coupling nut is also termed as extension nut which is a non-other than a fastener which is fully threaded for the purpose of joining the two male threads which are most commonly a threaded rod. The outer side of the fastener is usually found having a hex so that the wrench can hold it freely. There are variations which usually include the reduction of coupling nuts, for the purpose of joining two different sizes of threads along with the sight hole coupling nuts which are found having a sight hole which is made to observe the total amount of engagement along with the coupling nuts that are found being accompanied with the left-handed threads.
