The Threading Wire Forked (part # 8590) is an essential maintenance tool designed for Singer 29K Class industrial patcher sewing machines. Because the needle bar on these machines is hollow and quite long, this wire is used to pull the thread through the bar and down to the needle eye, making the threading process much easier.

Key Features:

• Forked Tip: Features a "perfect split" or forked end that securely catches the thread, making it significantly easier to guide through the long needle bar
• Length: Approximately 31.5cm (about 12.4 inches) to ensure it can reach completely through the assembly
• Material: High-quality steel construction for durability and flexibility during the threading process
• Design: Specifically engineered for hollow needle bar systems

Specifications:

• Part Number: 8590
• Type: Replacement (aftermarket)
• Total Length: 31.5cm (12.4 inches)
• Function: Thread guide for hollow needle bars

Machine Compatibility:

Singer 29 Series: 29-4 and various 29K models

Singer 29U Class: 29U171A, 29U172A, 29U173A

General Patcher Models: Often compatible with clones and similar "patcher" machines used for footwear and leather repair

How to Use:

Insert the forked end of the wire through the hollow needle bar from the top, push it through until it emerges at the needle end, catch your thread in the forked tip, then pull the wire back through the needle bar to thread the machine. This tool is indispensable for maintaining productivity on industrial patcher machines.
