Here's your solution, just go up one notch. No need to spend $$ on specialized parts.
Start using Grade-8 Bolts (6 Lines) You can find them at Lowes/Home Depot or even order through Grainger. They have a tensile strength of 150,000lbs, and usually gold/zinc plated and resist rust very very well. Also use Anti-sieze anytime you drop in bolts. These are very hard to break.
Stainless are the best for resisting rust, but are only equivilant to Grade 5, sometimes less. ( 110,000lbs)
Grade 5 are usually zinc coated and tend to rust quick, but still better than grade 2-3 or regular zinc bolts..
Hope this helps
