What to know before buying

Listing details to confirm

The listing's quantity details conflict: its title and feature text claim 1280 pieces, while the package breakdown totals 1281 pieces when its listed quantities are added. It also claims 400 nuts and 400 washers but lists eleven screw-length quantities totaling 480, plus one tweezer. Confirm the selected listing's count and exact kit contents before purchase. The general material field says stainless steel, while the feature text specifies 304 stainless steel, so grade is not consistently stated.

Who is it for?

A good fit for

People assembling or repairing equipment that uses M3 metric machine screws in several lengths.
Buyers who want an assortment of Phillips pan head screws with nuts and washers described in the listing.

Less suited to

Projects requiring a different thread size, head style, drive type, or a verified specific stainless-steel grade.
Buyers who need a confirmed exact quantity of every kit component without checking the listing details.

Aggregate ratings lean positive, with most ratings in the top category, but the distribution also includes lower ratings. With no review-summary evidence, these figures do not establish what buyers liked or disliked, or why. Treat them as a broad rating signal rather than evidence about fit, finish, or the disputed kit quantities.

Frequently asked questions

What screw sizes are listed?

The listing names eleven M3 lengths: 4, 6, 8, 10, 12, 14, 16, 18, 20, 25, and 30mm.

Are nuts and washers included?

The listing describes matching M3 nuts and flat washers, but its stated total and component quantities conflict. Check the selected listing for the exact package contents.

Is the material confirmed as 304 stainless steel?

The feature text calls it 304 stainless steel, but the technical details state only stainless steel. The grade is therefore inconsistent in the listing.
