Bobbin Case Tension Adjusting Screw for Singer Featherweight 221, 2...
Description
Description
The Bobbin Case Tension Adjusting Screw (part # 201016) is a miniature metal screw used to regulate the lower thread tension on vintage Singer Featherweight and 301 series sewing machines. This screw works by applying pressure to the bobbin case tension spring, allowing you to fine-tune the thread drag for consistent stitch quality. It is specifically designed for bobbin case #45750.
Specifications:
- Part Number: 201016
- Type: Replacement (aftermarket)
- Material: Durable steel
- Function: Regulates lower thread tension by applying pressure to bobbin case tension spring
- Compatible Bobbin Case: #45750
- Size: Miniature screw requiring precision screwdriver for adjustment
Machine Compatibility:
Singer Featherweight: 221, 221-1, 222, 222K
Singer 301 Series: 301, 301A
Alphasew Models: Alphasew 221 Featherweight
Function & Importance:
This tension adjusting screw is a critical component for achieving balanced stitch quality on vintage Singer machines. It regulates the lower thread tension by controlling the amount of pressure applied to the bobbin case tension spring, which determines how much drag or resistance the bobbin thread experiences as it unwinds. Even minor adjustments to this screw can resolve common sewing issues like skipped stitches, inconsistent thread looping on the top of the fabric, or unbalanced tension between upper and lower threads. The screw is made of durable steel to ensure longevity under constant thread movement and tension adjustments.
Important Note:
This is a small component that is frequently lost or damaged due to its miniature size and the precise screwdriver required for adjustment. Keep a spare on hand to avoid sewing interruptions. When adjusting bobbin tension, make small incremental turns (typically 1/8 to 1/4 turn at a time) and test stitch quality between adjustments.
Installation & Adjustment Note:
Install the tension adjusting screw into the bobbin case tension spring assembly. To adjust bobbin tension, turn the screw clockwise to increase tension (tighter thread drag) or counterclockwise to decrease tension (looser thread drag). Make small adjustments and test stitch quality on scrap fabric. Proper bobbin tension should allow the bobbin case to drop slightly when suspended by the thread, then stop without continuing to unwind.
