257018B56 (= JACK 30115067) Needle Plate for Pegasus W500 & JACK W4, K4 Flatlock

The 257018B56 needle plate is the genuine throat plate for Pegasus flatbed interlock (flatlock) machines. It is part of the same gauge assembly as the 257018B56 gauge set, which bundles the matching feed dog and presser components for this seam width — replacing the full set together keeps stitch width and fabric feed correctly matched.

के लिए सर्वश्रेष्ठ

Garment units running Pegasus flatlock/interlock seams (hemming, binding, flatlock decorative stitching) on knitwear and activewear, where plate wear shows up as skipped stitches or uneven flatlock coverage.

Why Replace This Plate

• Restores correct needle-hole alignment for flatlock and interlock stitch formation
• Smooth surface prevents fabric drag marks on delicate knits
• Matches the 257018B56 gauge set so stitch width stays consistent after replacement
• Reduces thread fraying caused by a chipped or grooved plate edge

How to Replace the Needle Plate

Switch off the machine and raise the presser foot. Remove the presser foot and cover, unscrew the worn plate, and fit the new 257018B56 plate with the needle holes aligned squarely under the needle bar. Tighten the screws evenly, then rotate the handwheel by hand to confirm clear needle passage before reattaching the presser foot and test-stitching on scrap fabric.

पूछे जाने वाले प्रश्न

Should I replace the full gauge set instead of just the plate? If the 257018B56 gauge set components are also worn, replacing the set keeps stitch width and feed correctly matched.

What if flatlock stitches still skip after fitting this plate? Check the loopers for wear and confirm needle height, since both affect flatlock stitch formation.

Does this fit standard interlock machines too? It fits Pegasus machines built around the 257018B56 hole pattern; confirm your machine’s existing plate carries this part number before ordering.
