Is there a way to reduce the step size granularity when adjusting transforms from Inspector?

I currently have a model that i have scaled down to <0.2f, 0.3f, 0.06f> in the inspector. Now I am trying to add a collider box that is a bit smaller. When I go about trying to scale, modify the position, etc. my collider box jumps all over when I’m trying to adjust the transform. I was wondering if there is a way to adjust the step size by holding a key or something so the movements are more granular?

What I have in the larger scope of things is a prefab that is a shelf, on that shelf i have products (which are scaled down) and then on that product I now need a collider at the barcode which i will use to calculate the hit of a raycast.

Thanks!

You should try giving the shelf itself a box collider and just use the collider scale editing button to adjust it.
