Ken Nelson Report post Posted September 26, 2018 I am on the hunt for the screw that attaches the Lift Bracket Link # 91-08 021-11 on a Pfaff 545 H4. I have come up with 2 different #'s for the screw. 91-000 237-25 and another place I come up with a number of 91-000 237-15. Does anyone have a couple of these screws they would be interested in selling or can anyone give me the correct size if they are available at a hardware store. Thanks for any help.

Uwe Report post Posted September 26, 2018 Not sure where you found the 91-000 237-25 reference - in my Pfaff 545 parts book ( Pfaff-145-545-Parts.pdf) that number is only used for the bobbin winder. My parts book does show the 91-000 237-25 screw in three places, two of them associated with the 91-008 021-11 lift bracket. In any case, that 91-000 237-15 screw on my Pfaff 545 appears to be a 3/16"-32 (3/16"=4.762mm, 32tpi=0.79375mm), which is almost identical to an M5-0.8, but an M5-0.8 does not thread into the hole on my Pfaff 545, the diameter is a tiny bit too wide. The 3/16"-32 (and the M5) is also very close the common #10-32 (.190"= 4.826mm) available at most hardware stores. You may get lucky with this one. All three screws have the same pitch for all practical purposes, but the thread diameter increases a small amount from 3/16" (4.762mm )to #10 (4.826mm) and to M5 (5mm). A #10-32 will usually thread into an M5 hole, but not the other way around. A #10-32 may also thread into a 3/16"-32 hole. Share this post Link to post Share on other sites
