1 / 7HELIFOUNER M3 Stainless Steel Button-Head Screw Kit, 500 Pieces
Stainless Steel: HELIFOUNER’s M3 button-head screw kit is listed with six screw lengths, nuts, flat and lock washers, and a claimed total of 500 pieces. Its range is useful for small metric fastening tasks, but the detailed package list adds tweezers and a hex wrench and does not match the stated screw-size quantities, so confirm the selected listing contents before relying on an exact count.

What to know before buying
Listing details to confirm
The listing is inconsistent about the set contents: its title and feature text claim 500 pieces, while the detailed count lists 120 screws, 120 nuts, 130 flat washers, 130 lock washers, one pair of tweezers and one hex wrench, totaling 502. It also describes six screw lengths but lists only 20 of each, which does not reconcile with the claimed total. Check the selected listing for the actual quantities and included tools. Customer feedback also mentions stripped screws and questions completeness, so inspect the fasteners on arrival. Keep small parts away from children because of the stated choking hazard.
Who is it for?
A good fit for
- People who need a range of short M3 metric button-head screws for small repairs or assembly.
- Buyers who want nuts and two washer types in the same assortment.
Less suited to
- Anyone needing a verified exact quantity of each component without confirming the detailed kit contents.
- Anyone who needs screw sizes other than M3 or lengths outside the six listed options.

Customer feedback appreciates the assortment of metric screw sizes, including a comment that it covers small-size needs. Reports on completeness are mixed, with feedback mentioning stripped screws and missing M6 nuts. This kit is specified as M3 only, so an M6 nut is outside its stated size range. The positive overall rating distribution is encouraging but cannot establish the condition or completeness of an individual kit.
Positive themes

Frequently asked questions
Which screw lengths are listed?
The listing names M3 screws in 6, 8, 10, 12, 16 and 20 mm lengths.
What material is specified?
The listing identifies the material as Stainless Steel 304 and the finish as passivated. These are listing claims, not independent verification.
Does the kit definitely contain 500 pieces?
The title claims 500, but the detailed component counts add up to 502 and the listed screw quantities do not align with a 500-piece total. Confirm the selected listing's contents before buying if the exact count matters.
Are a hex wrench and tweezers included?
Both appear in the detailed package list, but the broader package claim does not clearly reconcile with that inventory. Check the selected listing to confirm.
