Screw (½ in. U.H.)
A ½ in. screw used across several Triumph twin-cylinder assemblies, including the timing cover and points cover area.
70-7354 is a small ½ in. screw that shows up across a wide range of Triumph twin-cylinder fastener lists, most often tied to the timing cover and contact breaker area where it holds the points cover in place. The catalog also lists it in crankcase, gear cluster, and even petrol tank figures, so this is a general-purpose fastener Triumph used in more than one spot on the engine and elsewhere on the bike.

The legacy alias E7354 is the older book form of this same screw, and the catalog shows it superseding an earlier factory number, 70-8287 — so if your parts book or an old baggie of hardware turns up either of those numbers, you're looking at the same physical part.
Given how many different figures this one turns up in, don't assume it's only a points cover screw for your particular build — check the figure that matches the assembly you're working on before ordering, since Triumph clearly reused this fastener in several places.
