If you are looking for a 150#, 300#, & 600# Flange Stud Bolt Chart, we got you covered. Are you trying to figure out how many bolts you need to flange up the project you are working on? Regardless if its B7 studs, B8 studs, or teflon coated studs.
As fastener manufacturer, we got you covered. Bellow are ISO/DIN accepted thread pitch charts for commonly found metric fasteners. Here is Lightning Bolt’s Metric Bolt Thread Pitch Chart.
Need to know how many stud bolts and nuts are in a flange? Or how about an entire job? Let Lightning Bolt help… Below is ASME B16.5 150#, 300#, 600# Stud Bolt Flange Chart information that can assist engineers and pipe fitters with calculating the number of fasteners associated according to flange size. This is for informational purposes only. Novices should first make sure that they are looking at the appropriate flange class / schedule “poundage”. They, the user should look at the pipe size that they are needing. Once that is determined, the appropriate number of stud bolt will be found in the same line of the table. Feel free to reach out to us for all of your b7 bolts, b8 studs, and any other type of fasteners used when consulting an ASME B16.5 Stud Bolt Flange Chart.
