Eye bolts for harnesses - F-Body Road Racing and Autocross Forums

I just finished installing a 6 pt rollbar and harnesses and have a question about the eye bolts I'm using (for quick disconnect type snap ins). It seems when screwing them in to the stock belt locations they are a little wobbly until they are tight, and one that I was tightening (with a screwdriver through the eye - maybe a little too much torque) spun on me. But when I put the stock bolt back in it still snugged down very tight. So it seems that the diameter of the eye bolts is a little smaller than the stock bolts and the threads seem a little finer too when looking at them. Anyway I wrote the guy I got them from (soloracer.com - local) and he says they are the same ones used by Bell, G-force, etc, they are all the same, and has never had a complaint, except Porsche guys have to use some kind of adapter with them(?). I assume most serious folks here are using regular bolt ins and not snap ins/eye bolts, but does anyone using eye bolts know of some that fit better? I can get these fairly tight, but clearly they are not the same bolt as stock-
Thanks - don't know why I'm worried, its only the seatbelt (IMG:http://www.frrax.com/rrforum/style_emoticons/default/huh.gif)

I'm going to figure this out but I need a little help: 1. The ones available in metric thread are available in Plain Steel \| Zinc-Plated Steel \| Type 304 Stainless Steel \| Type 316 Stainless Steel - Should I be avoiding stainless? I guess it depends on the load rating- 2. They are available in several load ratings - anyone know the minimum load these should be able to handle? (an M20 handles about 6000lbs for example) 3. Metric sizes available are: M6 x 1 \| M7 x 1 \| M8 x 1.25 \| M10 x 1.5 \| M12 x 1.75 \| M14 x 2 \| M16 x 2 \| M18 x 2.5 \| M20 x 2.5 \| M24 x 3 \| M27 x 3 \| M30 x 3.5 \| M36 x 4 \| M42 x 4.5 \| M48 x 5 -Does anyone know the size off hand of our stock bolts? If not I will just take one down to lowes and get it measured. Thanks, I'll keep you posted-
