FS5W71B Righthand Thread Main Shaft Nuts

Newly machined, not NOS, M27X1.00 righthand thread main shaft nuts for the early FS5W71B 5-speed Datsun transmissions (may fit others). Made from 4140 Chromoly steel with a surface ground finish on the thrust face.


I was unable to find a replacement RH thread nut when rebuilding my transmission and had these commissioned from a local machinist. Made here in the USA. The pricing reflects these being the first and limited run of parts.


$60 shipped in the States.


Contact me with any interests or questions.

Did you try Nissan? The same left hand thread nut was used through '98 on the 240sx and at least 2004 in the Xterra and Frontier and maybe still today...on something. 2004 is as far as my Nissan information goes.



I did, and a few other vendors. All I could find were the later LH thread nuts. I had a hard time finding any M27X1.00 nuts, let alone ones with a collar to stake.
