T-Slot Nut 8 St M8, heavy-duty, bright zinc-plated - 0.0.420.83 T-Slot Nuts St, heavy-duty, can be used for very heavy-duty fastening applications.
Since their cross-section is adapted to the groove shape, tensile forces are guided into the aluminum profile.
They also have more supporting threads than the turn-to-insert T-Slot Nuts and thus allow greater screw tightening torques.

T-Slot Nuts St, heavy-duty are inserted into the profile groove in the end face where they are secured in position by means of a thrust piece.
