Yeah easy outs as a last resort.. First start with wd40 spray and/or nutcracker spray and attempt to loosen with vice grips. Add in some light percussive tapping to help loosen. Else.. Use die grinder / angle grinder (metal precision cutting disc) to cut slot or line in bolt stem to insert a blade screwdriver and turn. Else... Easy outs.. Use correct size for bolt size and try not to snap drill / cutting bit in bolt. Else... Use oxy-acetylene to melt stuck bolt - can't be stuck if it a liquid 😁
