Why Replace It
A worn needle bar stud introduces play into needle movement, which can throw off needle-to-hook timing and cause skipped stitches or needle breakage.
FAQ
Can a worn stud really cause skipped stitches?
Yes — even slight play in the needle bar changes the needle’s position relative to the hook at the critical moment of stitch formation.
