What is the set screw on side of freehub body for?

I have a HED Stinger wheel. On the side of the freehub body (on one of the splines) there is a small (too small for any of my allen wrenches) allen set screw. The guy at my LBS said he thinks it's just a hole where you can squirt lube into it, but he didnt seem very sure on that. Can someone please verify what it is for. I want to make sure it's not some sort of way to secure the freehub body to the hub/axle.

Bikes: '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

I'd also guess it's a lube port. Some freewheels used to have a hole under the cogs for that reason and I expect this is the same design. A set-screw that small (1.5 mm hex?) wouldn't be strong enough to have any real structural value.
