16C Dead Length Nut

The standard Hardinge® collet comes with a deep, precision-threaded section at the rear of the capacity bore to permit the use of Hardinge positive solid and ejector stops. Purchase a standard collet and it is always ready for stop work since the threaded capacity bore is found in all fractional, decimal, hexagon, square, rectangular, and emergency Hardinge collets within the ranges listed. The Hardinge solid, ejector, and long threaded stops are threaded into and positively locked against the end of the collet. Once locked in place, the stop cannot move even under heavy drilling or other end-working pressures. The three types of stops permit a wide variety of chucking work since all are adjustable and machinable for the desired part length to the maximum workpiece depths indicated.
