Nut
A 7/16 inch, 26 TPI nut used at multiple frame, suspension, and fitting points on Triumph twins.
DS47 is a 7/16 inch, 26 TPI nut used across a wide range of frame and fitting points on the bike. It shows up in the parts books under several figure headings — frame assembly, swinging fork and suspension units, engine and gearbox fittings, footrests, and exhaust pipes and silencers — which tells you this is a general-purpose fastener rather than something tied to one specific joint.

Given how many places it turns up (over forty catalog rows across the 1960s into 1970), it's worth keeping a few on hand in the parts bin. It's listed under the older DS 47 form as well as DS47, same nut either way.
Because it appears in so many different assemblies, don't assume which bolt or stud it's meant to pair with just from the number — match it to the fastener you're pulling it off of, or bring the old one in and we'll match it up.
