Thread: Singer 401A

All Singers of that age use a 15x1 needle. Yes, you can use Schmetz.

Yes, you can use a Schmetz or Singer or any other Singer compatible needle. I have a 401, and I use Schmetz and Singer. I use size 11, 14, and sometimes 16 Singer needles, and I use the Schmetz needles equal in size.

The 401s take the standard 15x1 needles. The brand makes no difference as long as it's the correct size and is a good needle.
