JORDAHL® Double-notch toothed T-bolts

    JORDAHL® double-notch toothed T-bolts are used with hot-rolled smooth JORDAHL® channels. When the T-bolts are tightened, their teeth bite into the channel lips to create a positive, non-slip connection to resist longitudinal loads. It is therefore possible to transmit force with plain hot-rolled JORDAHL® channels in all directions.
