The ””Countersunk Head”” version of the Hollo-Bolt is suitable for hollow sections or conventional steelwork where access is available from one side only. It also ensures that the fixing protrusion from the steelwork is kept to a minimum whilst still using a plain drilled hole in the supporting section and the outer plate / bracket.
Installation with standard tools is quick and simple and the final arrangement is neat and unobtrusive.
