Maxi-Lock Polyester Serger Thread – 50wt, 3000 Yards

Maxi-Lock Polyester Serger Thread is a go-to for high-speed sewing, trusted by professionals and home sewists alike. Each cone includes 3000 yards of 50-weight, 100% polyester thread built for sergers and sewing machines. It’s ideal for seam finishing, garment sewing, and interior bag construction.

While it's not heavy enough for topstitching or stress-point seams on heavy-duty bags, it holds up well for linings, lightweight accessories, and clean seam finishes. The thread resists shrinkage, UV damage, mildew, and abrasion—giving your projects long-lasting durability where it counts.

Available in a wide range of rich, vibrant colors.
