Longarm Needle Codes - What do Those Numbers Mean?

A few years ago, Groz-Beckert took over the Singer industrial needle division.  The old yellow Singer needle cases will soon disappear and all will be in the standard green Groz-Beckert packs.  If the label has a gold foil strip across the top, it is a titanium-coated needle.  If the word "Gebedur" is printed in the bottom right-hand corner of the label, it is a titanium-coated needle. Below is an explanation of what the different numbers mean on  Groz-Beckert longarm needles.

Most needles recommended for quilting have a slightly rounded sharp point, indicated by the code FFG.  The rounded sharp point allows the needle point to separate, then penetrate the fabric instead of cutting through everything.
