Honda K Series Post Mount Stud Bolt - Genuine OEM (90043-PZD-A00)
Swapping a K-series engine mount, building out a K-swap, or staring at a post mount stud that's all corroded, stripped, or snapped clean off? Here's your fix. This is the genuine Honda stud, part 90043-PZD-A00, and it's the M12 x 1.25 x 91mm post your K-series mount threads onto. It's a little piece, sure, but it's not one you want to reuse if the old one's been battling rust for the last twenty-some years. Drop a fresh one in and your mount bolts down clean and tight, no fuss.
What It Is And Why You're Probably Here
So here's where this little guy lives. It's the threaded post your K-series engine mount sits on and bolts to, so it's what holds that side of the mount to the motor. And there's usually one of a few reasons you're shopping for one. Maybe the old stud's so crusted up that the nut won't even thread on right. Maybe it got buggered up or stripped last time somebody pulled the mount. Or maybe you're putting a K-swap together and you just need the right hardware to bolt it all down. Whatever's going on, you want a clean, correct stud here, because if the threads are chewed or it's the wrong length, your mount won't snug down like it should, and let's be honest, engine mount hardware isn't where you want to cut corners.
Just Make Sure You've Got The Size Right
It's an M12 x 1.25 x 91mm stud, so that's 12mm across, Honda's fine 1.25 thread pitch, and 91mm long. Match that to what you're pulling out and you're good to go. And since it's the real Honda piece, the threads and the length are exactly what your K-series post mount was made for, so it threads right in. No guessing, no hardware-store stud that's close but not quite.
