What size fasteners does the Micro 5 fit?

It handles a minimum of 8 mm (5/16 in) and a maximum of 19 mm (3/4 in). Anything outside that range needs a different wrench.

How big and heavy is it?

It is 6 inches (152 mm) long and weighs about 0.28 lb (130 g), so it adds little to a tool bag.

No. It is sold as a tool only, with no case or accessories.

The jaw is spring loaded and sets itself to the fastener when you place it on the nut or bolt, so you do not dial in a size first.

For fasteners within its 8 mm to 19 mm range, yes, it can stand in for several fixed wrenches. Larger sizes still need separate tools.

Tradespeople and DIYers who work on small nuts and bolts in tight areas and want one compact tool instead of a handful of wrenches.
