For those of you who work with the DoD specifications, these topics call for editing by the engineer. For those of you who deal with flanged components, what type bolts, nuts, and washers do you buy? Do you even know what you are buying? NFPA 13 is pretty specific when it comes to piping and fittings, but silent I believe for bolts, nuts, washers. Maybe everyone except me knows this, if so, fill me in. Thank you. Bill Brooks William N. Brooks, P.E.
