Bemaka 580-Piece M3 Screw Kit, 304 Stainless Steel, 8 Lengths & Hex Wrench

M3 hardware in eight lengths gives this Bemaka kit flexibility for repairs and assembly work. The screws are made from 304 stainless steel with a passivated finish. Matching nuts, lock washers, and flat washers help you build a complete fastening setup. A labeled storage box keeps the assortment organized for selection as projects come up.

Usage tips

Choose from M3 screw lengths of 6, 8, 10, 12, 16, 20, 25, or 30 mm to suit the fastening depth of the job. The button-head screws use a hex socket drive, and the included hex wrench is ready for installation. Pair the screws with the matching nuts and washers when the assembly calls for them. The assortment is suited to practical work on 3D printers, electronic products, household appliances, furniture, toys, and precision machinery. Keeping the labeled box nearby makes it easier to sort through the lengths during a repair instead of sourcing each size separately.

Pros

Having several M3 lengths and matching hardware together is useful when a repair or build involves different fastening points. The kit contains 145 screws, 145 nuts, 145 lock washers, and 145 flat washers, so the components are grouped in equal quantities. Buyers appreciate the range of sizes and the kit’s versatility for hands-on projects. Feedback on durability is mixed: some buyers describe the screws as strong, while others report breakage. Some also mention that the case dividers can shift, so take care when moving the box to keep the parts sorted.

Highlights

Each screw has a button head and hex socket, combining a low-profile head shape with a drive designed for the included wrench. The 304 stainless steel construction and passivated finish are suited to projects where corrosion and oxidation resistance are useful considerations. The assortment covers eight lengths, from M3 x 6 mm through M3 x 30 mm, giving you options for different assembly depths without changing thread size. Its labeled plastic case supports organized storage, while the included nuts and both flat and lock washers provide matching components for common fastening arrangements. For a workbench handling small repairs, electronics, furniture, or 3D printer projects, this is a compact way to keep frequently used M3 hardware together.

Should you buy it?

It suits you if you need a varied M3 assortment for repairs or small builds and want screws, nuts, and washers in one organized kit. Compared with buying one screw length at a time, the eight-size selection offers more flexibility across projects, while the included hex wrench helps you get started with installation. The Bemaka kit is a practical fit for keeping metric fasteners on hand for household equipment, electronics, furniture, and precision work.
