  • T-nut with furrows
    Patent number: 4957402
    Abstract: A T-nut is disclosed for accurately affixing work beds to the base of a machine. The preferred nut comprises a generally flat head; a shank that is integral with and extends upwardly from the head; and a pair of furrows --one on each side of the shank, at its juncture with the head. The furrows are designed to straddle the burrs sometimes found in the T-slots of a machine base, so that the nut will sit flush within the slot, rather than be canted.
