Studs like this one thread into the crankcase or engine casting and give you a fixed point to clamp fittings down with a nut, rather than relying on a bolt head. Because it's a fastener with a specific length, getting the wrong one can leave you short on thread engagement or fouling something else, so it's worth double-checking against what you're pulling off the bike before you order.
Our catalog record doesn't tie this stud to one specific model or year — it just shows up across a number of entries in that 1964-1969 window. Call the shop and we'll help confirm fitment before you order.
