The thread size for a 350 Chevy cylinder head bolt is typically 7/16 inch, with a standard pitch of 14 threads per inch (TPI). This is common for the bolts used to secure the cylinder heads to the engine block in small block Chevrolet engines. It's important to ensure you use the correct bolts and torque specifications for proper engine assembly.
I believe it is 12mmX1.75 thread pitch.
A thread guide is a tool to measure the number and pitch of threads on a bolt
the parts of the screw are thread, pitch, and the last is bolt
6mm bolt with 1.0 thread pitch
You will probably have to re-thread unless you can get a SLIGHTLY over sized bolt to thread and seal
The crank bolt is right thread on a 96 geo metro. bob.
yes the Chevy in line 6 cylinder and the 350 share the same bolt pattern from 1963 and up.
Standard thread are meassured in number of threads per inch (example 1/4-20) 1/4 inch dia. bolt with 20 threads per inch. Metric threads are measured in mm between thread (M8 x 1.5), an 8 MM bolt with a thread pitch of 1.5MM between threads.
Yes, the bolt that holds the harmonic balancer in place on a 2001 Chevy Malibu is reverse thread. I learned that the hard way and stripped the head of my bolt down to nothing. And the bolt is almost impossible to find, because they no longer make them.

The deck is the surface to which you bolt the cylinder heads to.
Take the bolt to a machine shop and they can tell you . if you dont have it most metric auto bolts have a 125 thread pitch but i dont know the diameter.
