Yes we tested pan framing screw (TPI # 7-23).
This pan framing screw is the best we have received so far from your company. It may not be as good as the sample I sent you before but still better than previous one.
Tell me if that is the best pan framing screw you can make or if there is some room again for improvement ? We understand that this screw is very hard to make.
Thanks very much for all your help
