I've used two sponsor converters from here and they both came with bolts that are standard stock at Ace hardware, and were only metric grade 8.8, stock bolts are 10.9.
The industry standard bolt thread length engagement is 1 1/2 times the diameter of the bolt. None of the suppied bolts I've ever had were long enough going by that.
I have found that stock 70's, 80's style bolts, easily found in any auto parts store motormite Help section are the perfect size and are metric graded 9.8, and thats whats in my car now.

Verdad Gallardo The best thing to do would be to measure the thickness of the flexplate, add that to the bolt diameter x 1.5. Also add any shim thickness if needed.
Flexplate thickness + (bolt diameter x 1.5) = bolt you need.
Make sure they are either washer head bolts or have oversized hex heads.

^^^^ Exactly. You must figure out flexplate thickeness, shim thickness, and how far you want you bolt to go into the converter. Too long and it will bottom out. I bought some nice bolts from oriellys and cut them to the exact length I needed.
Metric is graded different than SAE.
Metric grade 10.9 is actually equal to SAE grade 8, both converters I bought came with 8.8's. Stock bolts are 10.9.
I know Ace hardware has a good selection metric bolts in grades 8.8, 9.8, 10.9, and 12.9 with the bigger 17mm hex head.
