Hello all:

        While looking for replacement tower fasteners, I noticed listings for 
types of bolts, SAE Gr5 and A325 Structural. Although identical in
appearance, they seem to be different metallurgically and intended for two
different purposes. Would I be correct to assume that A325 hardware would
be used for critical structural joints while SAE 5 should be used for
mounting of accessories and brackets ? Would they have different
torquing/tightening procdures ? The SAE series has well-published torque
specs - what about A325 ?

        Thanks - Pete Brush
