Essential for Older V-Twins
Ensure your seat is securely fastened with this Harddrive screw, specifically engineered for the 1/4-28 thread pitch found on older Harley-Davidson and Indian Motorcycle models. This is a critical detail, as 1996 and newer bikes use a different thread pitch. Confirm your bike's year to ensure proper fitment before ordering.
