Description
Description
Replacement regulating screw — Part #662. A precision metal tension adjustment screw for the shuttle hook assembly on Singer 29K and 29U industrial shoe patcher (cobbler) machines. Sold individually.
Works in tandem with Tension Spring #8611 to control bobbin thread pressure as it exits the shuttle hook. Adjusting this screw increases or decreases spring pressure for balanced upper and lower thread tension on leather and heavy materials.
Note: This screw is small and frequently lost during cleaning or maintenance — keeping a spare on hand prevents downtime.
