    Description:

    Stud Bolts are are fully threaded headless bolts used on Pipeline flanges for joining the pipelines. The main advantage of Stud Bolts over the Hex Bolts is that, it can be tightened from both the ends by holding one end with nut.

    The other type of Stud Bolt is the Engineering Stud which is also known as both end threaded bolt with unthreaded portion in the centre.

    Type: Full threads, Partial Threads, and customized as per requirements.

    Size: Nom Dia: ¼" to 4" [6-100 mm] *Tailor made if required. Length: As Per Standard or Upto any Length

    Torque Data For Use With Alloy Steel Stud Bolts

    Torque, is the measurement of the turning or twisting force applied to an object. This desired result is to hold two parts together with a tension or clamping force that is greater than any external force that could possibly separate them. The part then remains under constant stress and is immune to fatigue. The torque required to produce a certain stress in bolting is dependent upon a number of conditions, some of which are:


     Diameter of bolt
     Type and number of threads on bolt.
     Material on bolt.
     Condition of nut bearing surfaces.
     Lubrication of bolt threads and nut bearing surfaces.


    The tables below reflect the results of many tests to determine the relation between torque and bolt stress. Values are based on steel bolting well lubricated with a heavy graphite and oil mixture. It was found that a non-lubricated bolt has an efficiency of about 50% of a well lubricated bolt and also that different lubricants produce results varying between the limits of 50% - 100% of the tabulated stress figures.
