Listing details to confirm

Listing details are inconsistent or unconfirmed: the title and feature text describe 12.9-grade alloy steel with black oxide, while the specification block separately gives a 0.4mm pitch and the detail fields list M2-0.4. Confirm the exact thread and finish for your application. The supplied package breakdown lists 140 each of nuts, flat washers and lock washers, plus 20 screws at each of seven lengths, totaling 560 pieces.
