Tool-free bolt mod

Tired of carrying two crescent wrenches in my pocket while rigging/derigging my 26S, I modified some SS bolts to accept split rings and rounded the ends for easy insertion. I do worry that the split rings might catch ropes, but time will tell on that.
Tips on drilling stainless steel bolts:
Use a drill press.
Flatten the area you plan to drill with a Dremel tool or grinder. This will make starting the hole much easier.
Use good-quality bits - Bauer (available at Harbor Freight) worked for me.
Use oil when drilling.
Don't let the bolt get too hot. This will temper the stainless steel and make it next to impossible to drill.
