Hello everyone,

What are Cap Screws?
I came across this term when I was placing a Tripple Offset Butterfly Valve.
Why these are used with these type of valves.What if I forgot to mark these screws in BOM and issued only stud bolts in place of these?
should these be used in any other situation also?
if Yes I would like to know what are those situations.

Thank You
