WELDING STUD/ THREADED STUD

In manufacturing, a metal stud is a strong bolt used in the construction of buildings, motors, or manufacturing equipment. A threaded stud is a steal bolt that typically has threads on both sides. This bolt is screwed into a metal surface and placed between two objects. The object is secured with a nut on the adjacent threaded area of the bolt. Threaded studs are stronger then normal bolts because they are forged and cast into shape as a solid metal unit.

Threaded studs come in many sizes and materials.  These studs are used in all facets of construction and mechanical engineering. They are made of materials including stainless steel, aluminum, brass, and carbon steel.  Various types of studs are used for specific products, each of which require a particular material.

Stud welding is a form of spot welding where a bolt or nut is welded onto another metal part. The bolts may be automatically fed into the spot welder. Weld nuts generally have a flange with small nubs that melt to form the weld. Studs have a necked down, un-threaded area for the same purpose. Weld studs are used in stud welding systems.

The tip on the weld end of the stud serves a twofold purpose:

• It acts as a timing device to keep the stud off the base material
• It disintegrates when the trigger is pulled on the gun.

When the tip disintegrates, it melts and helps solidify the weld to the base material.

Stud welding also known as stud arc welding, joins a stud and another piece of metal together. The stud is usually joined to a flat plate by using the stud as one of the electrodes. 

Weld studs are used to secure back plates and various components to enclosure without making the reverse side marking. This type of studs are extremely cost-effective and durable.

Cage nut can be assembled easily into position without the need for special tools and it is consists of a square nut in a spring steel cage which wraps around the nut. The cage has two wings that when compressed allow the cage to be inserted into the square holes in equipment racks, and while released hold the nut in position behind the hole.

Using cage nuts mounted in square holes provides several benefits over threaded holes directly in the cage. First, one has the flexibility to choose the size of nuts and bolts at a time after the cage is installed.  Second, it is easy to  replace. Third, this can allow for a better strength-to-weight ratio, as only the nuts need to be made of a strong material suitable for threading.

The gap between the two wings determines thickness of material that will hold nut in correct position without pulling it from the base material. The size of square hole will also govern the position of nut. If size of hole is too large it will still pull out from base material. There are two types of cage nuts:

A) SLIDE-ON:

These nuts are used when rails are square punched because in such a case it becomes easy to move mounting hardware.

B) SNAP-IN:

These nuts are used for rails that are punched with square mountings in data cabinets.

The most common use for cage nuts is to mount equipment in square-holed 19-inch racks . There are four common sizes: 10-32 and to a lesser extent 12-24 are generally used in the United States; elsewhere M6 (6 mm outside diameter) for light and medium equipment and M8 for heavier equipment such as uninterruptible power supplies (UPSs).
