Iron will and Iron grip not apply to wand "projectile Attacks"

I was looking at the divergent kinetic bolt gem.

I was testing if either iron will or iron reflexes apply to this attack project gem.

Testing Iron Grip:

On testing the allocation of the Iron Grip node on the skill tree, the node does not work to apply to this projectile attack. No change occurred.

On testing the support gem Iron Grip, no change occurred. Yet the tag on the icon for the attack does appear for Iron Grip to the attack.

On testing Iron grip from the unique item Giantsbane the interaction is applied.

Testing Iron Will:

I linked the support gem Iron will to Kinetic Bolt, no change occured. No tag appears on attack icon.

I then equipped The Unique Repentance Gloves and the Iron Will on that item does apply.

Could you please clarify if these interacts are as intended. Are the interaction of the items in actuality different from the gems. As the testing I did would indicate they apply differently.

Iron Grip lets the physical damage increase from strength apply to projectile attacks as well. If Kinetic Bolt deals no physical damage (such as a pure elemental build using Piscator's Vigil or chaos using Replica Alberon's Warpath) Iron Grip will have no numerical effect. It does still apply to any physical damage dealt with projectile attacks, but you're not dealing any physical damage nor converting from physical.

Iron Will, as has been pointed out, can only support spell skills.
