They are cheap. They offer more surface area to the soil that a rebar so they don't tilt - especially if you sink them down to that flat piece on the side. Put a piece of scrap wood on the top when you bang it down with a hammer. Also they come with holes and clips both which facilitates hanging stuff. Save the rebar for something else.However, straight or hooked rebar may not provide the most effective anchorage and there are a few situations where headed bars may provide a desirable solution. When such headed bars are used, the required anchorage is achieved through bearing on the head or a combination of rebar bond and bearing on rebar deformations (see Fig.1) The advent of new 16-inch and 18-inch HP sections with higher allowable loads has necessitated the need of an expanded scope that includes pile allowable loads up to 400 tons. Assuming a factor of safety of 2, this implies in place pile loads up to 800 tons. The Guide also features expanded design tables to account for the higher allowable loads.The use of headed bars can therefore offer a distinct time and cost advantage as well as a potential improvement in concrete quality. Figure 3. The use of headed bars reduced the required bond/development length when compared to a hooked rebar anchorage.
