Drop-In T-Slot Nuts

Mount clamps and other fixtures to machine tool tables anywhere along the length of your T-slot track. These nuts install from the top and secure with a quarter turn, so you don’t have to slide them down the track’s length. They’re often paired with setup studs for adjustable fixtures. Also known as quarter-turn T-slot nuts.
