Hollow with Wrench Flats/One End Tapped:Related Image

[ ! ]Features of Low Temp. Black Chrome Plating >>P.128
[ ! ]Low temp. black chrome plating is not applied to the inside of hollow shafts, taps, bored holes and lateral holes, and may rust.
[ ! ]Circularity, Straightness, Perpendicularity and Changes in Hardness >>P.111
[ ! ]Circularity and O.D. tolerance may not meet precision specification in areas approximately 10mm from wrench flats machined ends.
[ ! ]Annealing may lower hardness at shaft end machined areas (effective thread length + approx. 10mm).
