I have two necks here. One is from my classic series 50s strat and the tenon measures 0.9" in thickness while another one from classic player 50s strat with tenon measures 0.95" in thickness. The latter has bigger frets and the resulted difference in total thickness at 17th fret is about 0.06" or 3.8/64th inch. The latter needs a lot of saddle raise to achieve same action when swapping necks. I asked here before and I thought necks all have the same tenon thickness regardless of back profile. I am wondering if this 0.05" (3.2/64th ) difference in thickness is within factory tolerance? And what is your experience with other quality after market replacement necks? Are the tenons all the same? All is there caution to be had? As said above, regardless of pitch of the tenon, the added thickness alone can cause drastic saddle raise - given the set screws are only 10mm (0.39") tall for inner 4 and 8mm for outter 2, they could easily max out. Thanks for your advice.
