Colleagues: need a recommendation as to drawer slides for drawers to hold some tools. Two cabinets about 18” w x 16-18” deep. Faceless frame; full extension. Seems there is not much a of a price difference between the 50 lbs. slides and the 75 lbs. rated slides?? The Little Voice says get the 75 lbs. slide.

I’ve looked around the Internet (AKA World Wide Wait) at the various hardware sites. But I have no knowledge which are good and those to avoid at all costs!

Also do the Allen keys/hex keys with the ball head ends actually work?

Periodically I need to tighten an armrest on my chair and using the “L” shaped Allen is not the most efficient due to space limitations.

Thanks for advice.
