Description

This 1.7 (dia) x 0.35 (mm/thd) x 4mm long bolt exactly matches the unique thread on the two bolt-holes on the faceplates of the GM11a, GM12a, GM13a, and GM14a gear motors. If you are looking for a way to precisely mount your motor, these bolts make the job much easier!

We’ve put the words “Screw/bolt” in the description to make it easier for people to use the search engine to find these.

You may ask, “What’s the difference between a bolt and a screw?”
It’s generally accepted that a fastener that has a defined number of threads-per-inch (1.6 per millimeter, in this case) and a consistent diameter all the way is a bolt, named by the threads-per-inch (or millimeter) by the length (1.6 per millimeter, x 4mm long). 
A screw usually tapers to a sharp point, and is usually named after the general screw diameter number, and length (#4 x 1.5″ for example).
