Key Features & Benefits
Secure Needle Retention: Engineered to provide a firm, vibration-resistant grip on the needle shank, preventing needle deflection or "creeping" during thick material penetration.

Hardened Steel Durability: Manufactured from industrial-grade hardened steel to resist the constant stress of needle changes and the vibrations of high-RPM production.

Precision Machined Threads: Cut to the exact specifications of part #414519, ensuring smooth installation and preventing damage to the needle bar's internal threads.

Flush-Fit Design: Designed to seat perfectly within the needle bar, ensuring it does not interfere with the presser foot or fabric during the sewing cycle.
