Anyone got a source for ribbed axle bolts? All the pics I see online are the smooth variety. I picked up a pair of axle bolts from VW a while back and they were also smooth. I don't have the tools for 150 lb-ft + 180°, so I'd much rather stick to the ribbed spec of 51 lb-ft + 90°.
The ribbed for her pleasure bolts may be NLA. Those smooth bolts may be the only game in town. A stronger bolt seems like a good change, plus you get to buy some new tools.

It's a stronger bolt? I thought they were both the same size/material? They should be at roughly the same clamping force, too. The only reason the non-ribbed bolt's torque spec is so much higher is that it experiences much less tightening friction than the ribbed bolt. So higher torque to achieve the same clamping force.
You guys are no help, I'm giving golfmk6 a 1 star review on Yelp

Usually when a part is updated and the older revisions are discontinued there's a reason. I personally feel way better about a smooth bolt with higher torque

Fair, but from a design perspective, the wheel bearing hub is the same and the internal threads on the axle shaft are the same. They're only designed to carry a certain clamping force, which is the value we actually need to be concerned with here -- that's what keeps the axle attached to the hub, not the torque. The only reason the smooth bolt has a higher torque is because the head is smoother and there are fewer friction losses. Same reason why some torque specs call for a higher torque on a bolt if you use some kind of lubricant on the threads versus a dry install, which will always call for a lower torque, all else being equal. Lower friction but same clamping force needs a higher torque value, and vice versa. I would bet money that the clamping force on the ribbed and non-ribbed bolts is the same and the only reason they switched to a non-ribbed bolt is because they're cheaper to make.
