Old metal plate wood truss
Old metal plate wood truss
(OP)
I came across these trusses today in a house built in 1967. I have seen similar trusses that use double shear nailing with cinched nails. These trusses were nailed from both sides with T-head nails about equal to a 3d or 4d common nail. Rather thin steel plates and many nails placed close to end joints. The trusses appear to be weak, but have not failed.
I assume the T-head nails were an early pneumatic nail. Is anyone familiar with the nails or the truss construction?

Lousy plate placement, no double cut on the webs, way too few fasteners. And those aren't truss plates - Just pieces of galvanized metal.
