Main Features & Creative Benefits

Tackle Heavy Fabrics with Ease: Finish seams on multiple layers of denim, layered knits, heavy canvas, and upholstery fabrics with complete precision. The Brother ST4031HD cuts and finishes fabric edges in one step for factory-quality results.

High-Durability Carbon Steel Knife Blade: The blade is manufactured from ultra-durable carbon steel, engineered to slice through thick, dense textiles cleanly without snagging or leaving frayed, uneven edges.

Heavy-Duty Interior Metal Frame: The rigid metal inner frame provides unwavering stability on your work table during high-speed sewing, preventing machine walking and vibration while extending the overall longevity of your machine.

Detachable Extra-Wide Extension Table: The included wide table supports bulky, heavy garments and quilts at needle level, eliminating fabric drag and preventing thread tension distortions caused by heavy material pulling off the edge.

Up to 1,300 Stitches Per Minute Speed: Finish your garment construction and seam finishing in fraction of the time. The variable-speed foot controller gives you complete, intuitive control over stitching speeds from slow detail work up to 1,300 SPM.

Solid Metal Thread Stand: Built from durable metal, the thread stand supports heavy spools and cones, directing thread upward cleanly for uninterrupted feed performance.

Versatile 3 or 4 Thread Capabilities: Use 4 threads for strong, structural overlock seams on woven fabrics, or switch to 3 threads for lightweight seam finishes, rolled hems, and stretchy knit apparel.

Color-Coded Threading Guides: Built-in color diagrams printed directly on the front panel map out each thread path clearly, eliminating guesswork during setup.

Removable Trim Trap: The included clip-on trim trap catches fabric scraps and trimmings as the knife cuts, keeping your work table clean and uncluttered.

Adjustable Differential Feed Ratio (0.7 to 2.0): Control the movement of front and rear feed dogs independently to prevent wavy, stretched seams on knits or puckering on lightweight woven fabrics.

Convenient Stitch Width Control Dial: Turn the external dial to adjust your stitch width between 5.0mm (3/16") and 7.0mm (9/32") so your serged seam finishes lay perfectly flat across various fabric thicknesses.
