Function & Benefits:
This horizontal spool pin is specifically engineered for Singer machines that utilize a top-loading, horizontal spool configuration. The pin holds the thread spool horizontally, allowing thread to unwind from the end of the spool rather than spinning off the side. This horizontal thread delivery is essential for modern cross-wound thread spools to prevent tangling, snapping, or inconsistent tension. The pin works together with the seat cap (#163148) which provides a stable base, and the lead off cap (#163149) which secures the spool on top, creating a complete horizontal thread delivery system for smooth, reliable thread feeding.
Related Parts:
This horizontal spool pin works with:
- Spool Pin Seat Cap #163148 - Provides stable base for spool
- Spool Pin Cap (Lead Off) #163149 - Secures spool on top
- Complete Spool Pin Set - Includes pin, seat cap, and lead off cap
Installation Note:
Install the horizontal spool pin in the designated spool pin holder. Place the seat cap (#163148) on the pin first to create a stable base, position the thread spool on the pin resting against the seat cap, then secure with the lead off cap (#163149) on top for complete horizontal thread delivery and spool retention.
