The information I have on the Z355 irons is also a .362" hosel bore size. .355" taper tip shafts will fit these irons. I would suggest using some Quck Center mixed with the epoxy to keep the shaft centered in the hosel bore. Srixon listed the stock steel shaft as a Nippon 950GH DST and I have a set of Nippon shafts that came out of a set of Srixon irons in the corner of my office and the tip measure .355".
