Child instantiated object to RayCastHit's parent.

Hello everyone! As the title suggests, I am trying to child an instantiated object to the PARENT of another object via RayCastHit.

The current code I am using childs a new instantiated object to hit.transform. What I need is it to child it to hit.transform's parent. I have tried hit.transform.parent, but no luck.

I have also looked up my issue through-out google and I have come here as the last resort.

If anyone in the community has the solution to my problem, please help as the answer has eluded me for FARRR too long :(

 function Build() 
 {
     if (HitBlock() && hit.transform.tag == "Block") 
     {
         if(sel1 == true)
         {
             var interF = GameObject.Instantiate(interFloor);
             interF.transform.position = hit.transform.position + hit.normal;
             interF.transform.tag = "Block";
             interF.transform.parent = hit.transform;
         }
     }
 }
