Thanks for asking. I suppose its all relative.

Compared to a phosphate bolt, our bolt has an enhanced heat treatment. The ARCOR Nitride provides superior hardness, wear resistance, and corrosion resistance and the cryo-stress relief is an arguably superior method of stress relief.

Compared to another premium Nitride bolt, then ours is not enhanced, it is comparable but made in Canada.

Yes we are working on this with the aim of June or July.
