Situation: Existing 1 3/4" A325 Ty 1 bolts for a 100T Halter Marine floating crane require rpl due to corrosion. Mystery is where did they come from since max dia A325 is 1.5". A325 is specified on dwg and bolts have A325 markings.
Don't have orig calcs so actual loads are unknown and diffucult...
Anyone know a substitute spec for A325 bolts? Have existing 1 3/4 dia bolts in a slip critical connection that need replacing. Dwg specifies A325 but max bolt dia in spec is 1 1/2". Vendor wants to sell me SAE J429.
