The hex bolts in my local home depot (specifically the size 3/8-16) all have the same thickness of the hex head. It looks to me to be about 3/16 of an inch thick. I need to recess a hex screw inside an aluminum block and recess a corresponding bolt on the other size of the aluminum block so the male hex bolt sticks out and is secure. However, because of the large thickness of the hex bolt head plus the thickness of the hex nut, it would require me to use a very thick piece of aluminum. Do they make thinner hex bolt heads/nuts so I could use a thinner piece of aluminum for the base?
This is for a baseplate stand for a camera system in my home, 3/8-16 is the standard base screw for all tripods I will be working with. Thank you for the help.
