If needing a jack hammer to drive them down, at 3/8" would use the straight ones and bend them after. The bent ones probably not made for hard ground. Not sure if a sledge would deform the bend too much. Try making a wood "socket" to fit over the end of the bar and give you something to pound on.Thus, hook development is a direct function of bar diameter db, which governs the magnitude of compressive stresses on the inside of the hook. Development length of a standard hook in tension is greater of 8db, 6 inches and the equation below: where: fy: specified yield strength of rebar in MPa fc': specified concrete compressive strength in MPa
