Hole-Mount Fixture Keys

Install these keys in a drilled and reamed hole to locate fixtures and vises on your machine table. They mount to the underside of the fixture or vise. Each key can fit multiple machine table T-slot widths. Also known as sine keys.
Expanding keys have a screw that tightens from the top or bottom to adjust the shank size, giving the key a tight fit in a hole in your fixture.
Push-in keys are the only fixture keys compatible with DX-series Kurt vises. Insert them into the holes on the bottom of the vise and built-in O-rings hold the keys in place. They are sold in pairs.
