Description
On the off chance that you had a thread jam and had to remove your bobbin case base in order to fix it, you may have had a gib hook screw that ran away from you in the process. This teeny tiny screw will sort that out for you, but be sure to select the correct variation from the options detailed below:
- Gib Hook Screw (NS) – this screw only fits the gib hook with part number 170160 found on a Singer Featherweight 221, 221K, 222K or 301
- Gib Hook Screw (R) – this screw only fits the gib hook with part number 45831 found on a Singer Featherweight 221, 221K, 222K or 301
