Members Spartan Posted January 11, 2017 Members Report Posted January 11, 2017 Hello all, I'm looking for needles for a singer 7-33, I need 7x5 but am having no luck with google. Quote
CowboyBob Posted January 11, 2017 Report Posted January 11, 2017 7x1 or 7x3 are round points,7x2 or 7x4 are leather point & either should work in your machine. Quote
Members Yetibelle Posted January 17, 2017 Members Report Posted January 17, 2017 7x1 and 7x2 - They are also referred to needles number 794 Groz-Beckert - DYX3 DYX2-LR. some have a round point then the LR leather needles have a sharp point. So that is the needle system, then you need to pick the size from 19-27. The larger the thread the bigger the needle size, •#92, #138, #207, #277, #346, #415, #554, #624, #690 You can go size 27 with thread #415 - I forgot what I had on the bottom maybe #277? Quote
Uwe Posted January 18, 2017 Report Posted January 18, 2017 So what are "7x5" needles then? Are they real, mystical creatures, or a typo? Quote
Members Spartan Posted January 18, 2017 Author Members Report Posted January 18, 2017 (edited) Thank you guys very much! Other than the original manual I couldn't find any information so this made my day! Uwe, according to the manual, it calls for 7x5 for leather, but i couldn't find any information on them so I came to the experts. Edited January 18, 2017 by Spartan Quote
Uwe Posted January 18, 2017 Report Posted January 18, 2017 (edited) I just looked up my Singer 7-33 manual. It looks to me like fabric needles from size 19-27 belong to system 7x1, and starting with size 28 through 31 the needles belong to system 7x5. I've seen needles where the shank is actually thinner than main part of the needle, perhaps the 7x5 system belong in that category. In most "normal" needle systems the main part of the needle is the same or thinner than the shank, but not thicker. Edited January 18, 2017 by Uwe Quote
Members Yetibelle Posted January 18, 2017 Members Report Posted January 18, 2017 That is odd on page 4 sure enough - top of the page it says 7x1 and 7x2 then goes on to mention the 7x5 and 7x6 in HUGE size 28-31? I want a size 31 leather needle! haha Quote
Uwe Posted January 18, 2017 Report Posted January 18, 2017 (edited) My needle is bigger than yours. I actually managed to find my mystery monster needle where the shank is thinner than the main part of the needle. Here's a picture comparing it to a System 7x3 size 27 needle: Edited January 18, 2017 by Uwe Quote

Members Constabulary Posted January 18, 2017 Members Report Posted January 18, 2017 arent these the System 331 needles for BUSMC#6 and the like - I have to measure... Not sure Quote
Uwe Posted January 18, 2017 Report Posted January 18, 2017 (edited) System 331 (Size 10) is indeed a candidate for my mystery needle, according to this Schmetz Needle Size Comparison Chart at Universal Sewing. In the Singer world it would be a size "30". The Singer 7-33 takes a needle 7x5 Size 31 that is one size bigger than mine, at 350 Nm or 3.5 mm thick. Edited January 18, 2017 by Uwe Quote
Members Constabulary Posted January 19, 2017 Members Report Posted January 19, 2017 right, 331 have no scarf and are longer then Uwe´s (sewing) needle - so maybe it is for a bag closing machine (a guess) Quote
