307a Bolt ?


Recommended Posts

Anyone have a guesstimate as to how hard these are at 6" X 5/16"? The 307A CYI really gave up after the kink and crushed really easily and the 307a SD is at about 90 degrees after two sessions. Just wondering. I plan on hopefully finishing the SD this weekend.

I'm not sure I've seen an SD marked bolt, but I think the CYI G2's are the easiest I've come across (I even bent one reverse). I'd say in general the kink of a 5/16" G2 isn't too far off a red nail, but as you already noticed they crush very easily compared to CRS.

Thanks for the info. The CYI is a fun bend because once you get the kink it's real easy. The SD is a lot harder. It feels good to bend something 5/16.

I was looking at some of my other bolts. I have 307a L and 307a DF as well, along with BL bolts...BL's seem to vary more than the 307a variety.
