M3 Socket Head Cap Screw Kit 760pcs

This Bemaka kit supplies 760 pieces of M3 socket head cap screws in eight lengths from 6 mm to 30 mm. It includes matching nuts, lock washers, flat washers and a hex wrench in a labelled plastic box. The screws are 12.9 grade alloy steel for high strength and corrosion resistance. The assortment targets repair, 3D printing, electronics and general DIY work.

Suits makers needing a ready M3 fastener range

The kit covers the common M3 sizes used in printers, small mechanisms and household repairs. Builders who require larger diameters, longer lengths or different drive styles should look elsewhere. Users needing stainless steel or graded certification documents will not find them here. The pack is not designed for structural steel connections.

Eight lengths give broad M3 coverage

Quantities per size are 42, 40, 35, 35, 30, 30, 20 and 18 pieces respectively, plus 255 each of nuts, lock washers and flat washers. This depth handles repeated small jobs and prototyping without reordering. Very high-volume production or non-M3 threads will exhaust the kit quickly. The 12.9 grade handles typical machine loads but not extreme shear.

Questions about this item

What tools do I already need to install these M3 socket head cap screws?

The kit includes a hex wrench for the hex socket drive, so no additional tools are required for installation.

Can I mix these 12.9 grade alloy steel screws with existing lower-grade fasteners in the same assembly?

These M3 screws are 12.9 grade alloy steel, which is stronger than common lower grades; mixing grades in a critical joint is not recommended.

How do I confirm the kit contains all 760 pieces after opening the box?

The labeled plastic box organizes 760 pieces across 8 screw lengths, 255 nuts, 255 lock washers, 255 flat washers, and a hex wrench.
