M2 Carbon Steel Hex Nut (Black)

Exactly the right size for the M2 screws in my Arduino shield kits, and the black finish actually holds up to repeated tightening without flaking off. Each pack of ten gives me plenty of spares, so I've got a small stash for future builds without any worry.

Needed a few of these for a small electronics project and was relieved the M2 threading caught smoothly on my standoffs. The black finish looks clean and professional against the circuit board.

The black finish on these M2 nuts matches perfectly with my DIY electronics project, and they threaded onto the bolts without any stripping. Exactly what I needed for securing a small shield board.
