Devices used when connecting truss sections to each other, or to corner blocks or hinge plates.
For bolted connections, consists minimally of a 15/16" box/open end combination wrench and a 15/16" deep-well socket and ratchet handle.
A drift pin is also desirable, but not required.
The Klein Tools 3238 is a socket wrench and a drift pin all in one which can help speed up building truss.

For spigot connections, a dead blow mallet is usually all that is needed to drive the truss pins.
