ABSTRACT:
Refractory concrete blocks e.g. furnace wall lining blocks, have a through hole for attachment of the block to a support by a bolt. The hole has a narrow portion next the support and a wider portion more remote therefrom having a keying configuration so refractory paste inserted after installation to protect the bolt head does not drop out in use.
