The Talking Machine Forum — For All Antique Phonographs & Recordings

Hi:

I need the Thumb bolt for a Heineman tone arm that goes through the tone arm into the reproducer, the thumb bolt is for securing the reproducer between moves from lateral to vertical records.

I know this doesn't really help you, but what you want is a "Thumb Screw".

What may help is if you could post a photo of the arm, showing where the screw belongs.

Here are pictures of the hole and the screw I put in to hold it.

I had one on a reproducer that broke years ago, and replaced with another generic arm, instead of saving the arm and thumbscrew, I ended up trading it for another arm until I found this one like the original with reproducer.
