Holokrome is sold by fastenal and is still USA made for this particular bolt. It was suggested to use on the Macs. guys were saying how good they were. I had lost 2 engines to them. I also lost 1 engine to the genuine Mac 91 bolts and one had the bolt break in the rod at the joint and the head blow through the stuffer, killing the engine before it could finish coming apart. the rod was damaged from movement after the break but that engine stayed together. Had a friend have 101 rod bolts pop the heads off sitting still not running. went to start it and clankty clank. No rod cap on the rod. It's your choice. when I pull my engines down i know what rod bolt they are getting. I've not had a WB break the special bolt at this point. The aero space WB bolt can be shortened and used in Macs.
