(2)What are hex bolts used for? Hex bolts, or hex cap screws, are large bolts with a six-sided head (hexagonal) used to fasten wood to wood, or metal to wood. (3)How do you remove a hex bolt? Use a hammer to tap against the hex-key wrench in extreme cases. Pour a few drops of household oil or spray a shot of aerosol lubricant on screw heads that do not come loose with the additional tools. Allow 20 minutes for the lubricant to work in between the threads before attempting removal.
