What to know before buying
Listing details to confirm
Listing details are inconsistent: the listing identifies both flat and round heads, gives UNC and metric thread descriptions, and includes an M3x16mm fastener size despite describing nine size combinations. Confirm the exact screw profile and assortment before purchase. The corrosion-resistance and ease-of-installation statements are manufacturer claims, not independently established performance.
Who is it for?
A good fit for
- DIYers and home repairers who want several small screw sizes for wood, furniture or cabinet projects.
- Buyers who prefer screws stored in separate labelled compartments.
Less suited to
- Anyone who needs a single precisely specified screw type or confirmed head and thread details without checking the assortment.
