Maintain the structural stability and timing precision of your button-sewing equipment with the premium B1213-372-000/NS-6150430-SP Screw For Juki MB 372/373. In commercial apparel manufacturing, the small components often bear the highest load. This specialized screw is built to withstand the continuous, high-frequency impact energy generated by your machine’s stop-motion system.

Key Features & Benefits

• Precision Engineering: Machined with the exact thread pitch and length required to fit the Juki MB-372 and MB-373 frames, ensuring a flush, vibration-resistant lock.

• Hardened Steel Construction: Forged from high-grade, industrial steel to resist thread stripping, head shearing, and mechanical wear under continuous factory stress.

• Maintains Stop Motion Alignment: Firmly clamps down on your B1212-372 / B1211-372 disc pawl, eliminating any structural “play” or shifting that could ruin machine timing.

Why Use Factory-Spec Juki Replacement Screws?

Using generic or incorrectly threaded screws can destroy the internal threading of your machine body, leading to incredibly expensive repairs. A worn or slightly loose B1213-372-000 / NS-6150430-SP Screw allows the stop motion disc pawl to wobble. This minor instability causes delayed braking, loud clicking sounds, skipped cycles, or severe needle and looper collisions. Upgrading to a fresh, factory-tolerance screw ensures your stop-motion system operates perfectly, minimizing unexpected workshop downtime.
