Type Countersunk Hollo-Bolt

The Hollo-Bolt is the Original Expansion Bolt for Structural Steel. The 'Countersunk Head' version is suitable for hollow sections or conventional steel where access is available from one side only. This steel expansion bolt also ensures that product  protrusion from the steel 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 unobstrusive.
Available in sizes 5/16" to 5/8".
