[TowerTalk] 3/4" x 27" Anchor Bolts for an MA-40 Crank up tubular mast w/MARB

Question: I picked up a nice MA-40 with MARB, and am installing it  myself 
at my QTH. IS there any thing special about the 3/4" x 27"  Anchor Bolts. I 
need all four but they are about 50$ each plus 50$ for  shipping, close to 
what I paid for the entire tower set up!. I will  not scrimp for safety 
reasons if the Mfr bolts are THE ONES to use. But was  wondering about 
alternatives?? Maybe something locally from Home  depot? 
SAFETY first in any case and if it costs $250 for the right bolts so  be 
it! Tnx
