Certainty. A screw collar has to be wound open deliberately, so nothing short of you undoing it will release the hook. That's the one to use where a line can twist and work a spring gate open — a dinghy painter, a dog on deck, a canopy corner.
Match the thimble to your rope, not the other way around. The 6 mm eye is sized for light line — a painter, a fender lanyard, a lifeline tail. Force thicker rope in and the splice sits proud, chafes on the thimble edge and fails where you can't see it.
No. This is rigging and fastening hardware with no published load rating, so it has no business on a harness, a safety line for a person, or anything overhead. Use certified gear with a stamped rating for that, and keep this for canopies, lanyards and gear.
