Drop-In T-Slot Nuts
Install these nuts from the top of the T-slot track and secure with a quarter turn to anchor clamps and workpieces. Also known as quarter-turn T-slot nuts.
Fully threaded nuts allow a stud to extend beyond the bottom of the nut.
Partially threaded nuts keep studs from traveling past the bottom of the nut and damaging your table.
