Screw outer cover to inner
Allen screw, 1/4 UNC by roughly 1-1/4 inch, used to secure outer covers to inner covers on various engine and gearbox assemblies.
14-7007 is an Allen screw used to fasten an outer cover to an inner cover or housing. It shows up across a wide range of parts-book figures over the years, including timing covers, gearbox outer cover, oil pump and release valve, cylinder block and head, and even a front fork listing, which tells you this is a general-purpose fixing rather than a one-spot special.

Catalog appearances run from 1973 through 1985, so it's a fastener Triumph used across a good number of build years for this kind of cover-to-cover fixing. Given how often it turns up, it's worth having a few of these on hand when you're pulling covers apart for gasket work or inspection.
The screw is a 1/4 inch UNC Allen-head fastener, roughly 1-1/4 inch long. If you're not sure which cover on your bike takes this exact screw, check your parts book figure or give the shop a call before ordering.
