These are also called Sheet Metal screws or full threaded screws. As the name suggests these are screws which are fully threaded to give a firm grip in any fixture. They are zinc plated and also available in stainless steel. They are used in furniture and also in sheet metal work and any metal to metal affixation.
They are generally available in multiples of 1000 nos depending upon the size. They are available in diameter ranging from 3 mm up to 6 mm and in length varying from 4.5 mm up to 100 mm.
For furniture work we require self tapping screws in Counter sunk head (CSK) and for aluminum window work or any metal to metal affixation we require Pan head screws.
The head is punched in Slotted head or Phillips head. These screws cannot self drill but are to be tapered in any material until it is tightened.
These screws are used for quick, easy and cost effective work. These screws have fine threading for giving a firm grip.
