Evo160K Report post Posted February 11, 2018 While searching the internet for the thread size on a Singer No. 69 screw, I stumbled upon the link below that seems to contain some extremely important information (for me at least) on thread sizes, including Singer, and how they're determined. Experienced members most likely know this. One of the people responding to the post seems to have some good tips. https://groups.io/g/Wheeler_and_Wilson-Sewing-Machines/topic/493006?p=,,,20,0,0,0::,,,0,0,0,493006 By the way, does anyone know the size of the threads on a Singer 69 screw?

brmax Report post Posted February 12, 2018 Sorry I dont know the thread type. Are you in need of a replacement or just want to repair the area. Im sure some of the members can discuss the particular machine model and direct toward a repair. Good day Floyd Quote Share this post Link to post Share on other sites
Evo160K Report post Posted February 12, 2018 brmax, Both.....a replacement and a repair of the area. I snapped the screw in two while trying to remove it, so I need to drill out and tap the hole, plus I need a replacement screw. I can/will make a repair, but I would like to keep it original Simanco if I can. Thank you for your interest. Quote Share this post Link to post Share on other sites
Uwe Report post Posted February 12, 2018 I'm afraid the Simanco part number and picture alone is not enough information. It should be, but it's not. There's no cross-reference that correlates Singer screw part numbers to thread size that I know of. There's isn't even a good way to find out which Singer machines that screw was used in. The usual wholesale vendor suspects do not show that screw part number at all. If you can tell us what machine model the screw came from and where on the machine that screw is located (a photo of the crime scene would be great!) then we have a better chance to figure out what the thread size is.

Evo160K Report post Posted February 12, 2018 Uwe, The screw is used on a Singer 45K69 to hold the spirit box cover on to the sprit box while allowing the cover to rotate.. "There's no cross-reference that correlates Singer screw part numbers to thread size that I know of. " This website, singersewinginfo.co.uk, has them and more, but not the 69. : http://www.singersewinginfo.co.uk/screw_threads/ Thanks Uwe Quote Share this post Link to post Share on other sites
