Frequently Asked Questions

Will this fit my pre-1996 V-twin?

No — pre-1996 models use 1/4-28 thread pitch. This screw is 1/4-20 and will not thread into older seat pans.

Does the washer come installed?

The washer is included in the package. Install it between the knob head and the seat pan for proper seating.

What's the difference between 1/4-20 and 1/4-28?

Thread pitch refers to how many threads are cut per inch. Pre-96 bikes use tighter 1/4-28 spacing; 1996+ V-twins switched to the looser 1/4-20 standard.
