Frequently Asked Questions

What thread size is the screw?

1/4-20 — a common V-twin motorcycle seat fastener size. Verify your bike uses this size before ordering.

Does it come with the o-ring?

Yes — the o-ring is integral to the screw body, so no separate gasket is needed.

Is this a direct replacement for my factory seat screw?

It replaces factory fasteners on V-twin models that use 1/4-20 threads. Confirm your bike's fastener size matches before installation.

What makes these different from stock fasteners?

CNC machined billet aluminum construction with a custom engraved Hofmann logo — adds style while delivering the same function as OEM fasteners.
