A 17/32 in. U.H. bolt used in the swinging fork and chainguard area, cataloged for 1966.
This is a 17/32 in. U.H. bolt listed in the swinging fork, suspension units and chainguard section of the parts book, appearing in catalog records tied to 1966. Its older factory number was W840, which some earlier parts books may still reference if you're cross-checking against a pre-1973-style listing.

Given the figure it shows up under, it's a fastener that lives somewhere around the rear suspension and chainguard area of the frame. The catalog entry itself is brief, so we can't say more about exactly which mounting point it's used on without pulling the actual diagram.
If you're restoring a bike from this era and matching original hardware, it's worth confirming against your specific frame and chainguard setup before ordering, since fasteners in this area can look similar but differ in length or head style.
