I always figure a crossbolt might just as well look like a crossbolt but there are some qualifications. The purpose is to prevent the stock from splitting rather than to transfer recoil forces to the wood, so placement is important. A crossbolt between the magazine cutout and the trigger group is beneficial.
As far as the threaded rod through the grip is concerned, if the flow of the grain through the grip is wrong, reinforcement can help. If the grain flows well, it doesn't make a big difference. GD
