コーンネジアダプター

I’ve been using these adapters for a week now and the cone sits so securely on my machine’s spindle — no wobbling at all even when serging at high speed. The insert goes into the large end easily and keeps everything steady.

I was skeptical the cone would wobble on my serger, but the adapter fit snugly into the large end and held everything steady through a whole project. It's a cheap, simple fix that does exactly what it says.

The little plastic adapter slipped right into my cone spools and now my serger threads stay put without tipping over. Makes switching between different cone sizes much less fiddly for under five bucks.
