Anyone have the part number handy?

3/8" 6 or 12 points are too tough to get to, looking for the 5/16

Thanks!

144-1202 is black 12 point 5/16
444-1202 is stainless 12 point 5/16

144-1102 is black hex 5/16
444-1102 is stainless hex 5/16

Hope this helps

Well, the good news is that Summit ships very quickly and I received the bolts.

The BAD news is these are NOT 5/16 12 point heads, they are 3/8"-12 point heads so I can't use them.

The thread is correct 5/16-18 Threads per inch but the 12 point head of the bolt is too big to get a wrench on.

I used stage 8 bolts(P/N 8935) on my 5.9 Dak,the bad thing was that they were expensive and the locking tabs were too big to fit the tight bends on the JBA shortys,but the good thing was they did have a 12pt 5/16th head,D

Maybe McMaster Carr? I've bought their small head 12pt bolts for slant six use before. I had to use 6 points on my LA hookers- the outside pipes are tight to get anything but an open ender on there.

How bout allens?
