ARP fasteners?

[jarhead]

Do the ARP fasteners have a rolled thread?

I know they are stronger than a regular bolt, just curious if thread fitment is a little nicer than say a single point type of thread.

Thanks!

The two tool-steel rollers press into the fillet under the head, compressing the material giving it greater fatigue resistance. The final mechanical process is rolling the threads. ARP uses two basic types of thread rollers. ... The other type uses three thread dies to roll the thread.

Crazy Story:
When I built the 68 Camaro, I insisted on all ARP fasteners
Where bolts are NONCRITICAL, like hinge bolts for hideaway headlamp doors,
where ARP does not provide required length,
I would cut an ARP bolt head about 1/2” down and TIG weld the shank to the ARP head.
