What tools can I use for the installation of bolt connectors except for the spanners?
A set of spanners is not what you need for the installation of bolt connectors. The best choice for this work is set that contains changeable hex sockets of different sizes, a ratchet key and a support tool frame for fixation of the connector before the operation. This all KBT has in one set called НМБ-6. The set is in a fabric bag. It is the best investment for electricians.
