| Does anyone know the specifications on the Genie Screw Drive garage door opener screw? I have a source for the screws and if I can find a matching anti-backlash nut I think I might try them out. The goal is a low cost performance increase over my 13 TPI single start all thread screw. Based on my physical inspection of the genie part I think the specs are: - 1/2" OD - 3 starts - 8 Threads Per Inch (TPI) But I am not sure if it is an ACME thread or some other (Worm maybe). I have called Genie, but I have not yet been able to get any technical data. Has anyone else looked into this? Thanks! -Dave P. Last edited by daprice; 09-02-2010 at 01:54 PM.  |
