luvmr201-30-2016, 05:26 PMQuick question, anyone know the size of the headbolt on a 20V Silvertop engine?

It is not a bolt head, I think they call it a Torx head.

Any help will be great.

Thanks yoshimitsuspeed01-30-2016, 07:06 PMI forget the length but i could check. I have to ask why? It's not like you are going to walk down to the hardware store for replacements. What are you trying to do? luvmr201-31-2016, 03:44 PMWhat size it the Torx bit to remove the bolt is what I should have said. yoshimitsuspeed01-31-2016, 04:58 PMThey should be a 12 point double hex. A regular hex socket should work. 10mm if i remember right. Powered by vBulletin® Version 4.2.5 Copyright © 2026 vBulletin Solutions Inc. All rights reserved.
