Common questions
Will this knob seat screw fit my 1996 and newer Harley or Indian?
No, this screw has a 1/4-28 thread pitch, which is for pre-1996 V-twin models. 1996 and newer bikes use a 1/4-20 thread pitch and will not be compatible.
What is included with this seat screw?
The seat screw comes with the chrome knob head and a washer, ready for immediate installation.
How can I tell if my bike needs 1/4-28 or 1/4-20 thread pitch?
If your V-twin motorcycle was manufactured before 1996, it will typically require a 1/4-28 thread pitch. Models from 1996 onwards use 1/4-20. Always verify your bike's model year to ensure correct fitment.
