Ok, I have a small problem......

I have the Holley FP Regulator part # 512-506.

Well the allen wrench style adjustment screw decided to sheer off today after I had adjusted my static FP, anyway..... Can anyone tell me what size and pitch of thread that screw is???????

Thanks,
Tim

 

Best thing to do is, bring it into your local hardware store (lowes, home depot) and match up the threads that way. I know lowes has most of the common sizes and a cool thread checker.

hope that helps.
