Bolt, damper, lower—L.H.
3/8 UNF x 1-3/4 inch hex bolt, left-hand lower damper bolt per Triumph's parts book, used across several fork and suspension mounting points.
14-0234 is a hex-head bolt that Triumph's books list as the lower damper bolt, left-hand side. It shows up across a wide run of catalog figures — front fork, swinging arm and suspension units, rear carrier and safety bars, and even the motor unit fittings and footrests pages — which tells you this is a general-purpose mounting bolt Triumph used in more than one spot rather than a single dedicated part. The thread is 3/8 UNF, with an overall length of 1-3/4 inch.

Because it's called out as L.H. in the parts book, make sure you're ordering it for the correct side rather than assuming it's interchangeable side to side. Given how many different assemblies it turns up in across the catalog spread from 1969 to 1985, it's worth checking your bike's specific fork, swinging arm, or fitting point against the parts book diagram before you order, since the same bolt gets called on for different jobs depending on the model and year.
If you're working from an older parts book, you may see this listed as 14-234 — same bolt, just the shorter number form. Keep a couple on hand if you're pulling apart the front end or rear suspension mounts, since small bolts like this have a way of walking off during a teardown.
