Daniel ★★★★★

Needed some tiny stainless screws for a repair on a telescope mount, and these internal tooth washers locked in place perfectly. No stripping or mangling even on the second use.

Lily ★★★★★

Phillips drive seated cleanly on every one of the 200 I’ve used so far, and the 18-8 stainless finish hasn’t shown a hint of corrosion after a few weeks of assembly work. Pan heads sit flush without stripping, which is more than I can say for cheaper packs I’ve tried.

Lily ★★★★★

The pack of 200 gives me plenty of spares for my electronics projects, and the phillips drive sits snug in the driver without stripping. The 18-8 stainless has a nice clean finish, and the built-in lock washer cuts down on extra parts to hunt for.
