Types of Thread

  1. BSP THREAD
    2. British Standard Pipe (BSP) has been used in plumbing and pipe fittings and It is also known as Whitworth 55°

    There are two types of BSP Thread:-
    1. Parallel threads OR Straight threads : Parallel thread have a constant diameter.
    2. Thread : Tapper thread which diameter increases or decreases along with the length of the thread
  2. BSPP THREAD
    • British Standard Pipe Parallel (BSPP)
    • British Standard Pipe Fitting (BSPF)
    • British Standard Pipe Mechanical (BSPM)
      • These all are same

      In this, Male thread and Female thread both are parallel. It has been used where a pressure-tight joint is achieved by the compression of a soft material (such as an O-ring seal or a washer) between the end face of a male thread and a socket or nipple face, with the tightening of a back nut. Thread form as per AS 1722.1, BS 21, ISO 7


  3. BSPT THREAD

    4. British Standard Pipe Taper thread (BSPT) which diameter increases or decreases along with the length of the thread.

    BSPT thread are used where pressure-tightness is made through the mating of two threads together. In International standards, it require all the Female threads are parallel and male threads are tapered. Female threads can also be tapered but it is not an ideal. Thread form as per AS 1722.1, BS 21, ISO 7


Thread Count(TPI)

Threads Per Inch, Means the total number of threads per inch are measured along with the length of a fastener. TPI is only using in American fasteners. In smaller fasteners the threads are finer, so the thread count will be higher.

Thread Pitch

Thread Pitch is used in Metric fasteners which are specified with a thread pitch instead of a thread count. The thread pitch is the distance between threads expressed in millimeter. Smaller fasteners have finer thread so that they have lower thread pitch.

FREE CUTTING BRASS ROD

Free Cutting Brass is also known as Leaded Brass which contains 56 to 63% of Copper, 2 to 3.50% Lead and remaining of Zinc. The addition of Lead reduces wear on the cutting tool, and it permits part to be processed rapidly on automatic machines. Good strength and ductility are combined with excellent corrosion resistance. Free Cutting Brass set the standard by which the machinability of other materials is judged. The usage of Free Cutting Brass ensures cost effectiveness via application of close tolerance manufacturing techniques and reducing tooling costs. Apart from these benefits, the high value of any process scrap can be used to reduce the production costs significantly. So we are using these high quality brass rods having different grades as given below with its technical details.
