M3 Screw Assortment Kit 720pcs

This M3 screw assortment kit provides 720 pieces including 180pcs hex socket head cap bolts, 180pcs hex nuts, 180pcs flat washers, 180pcs spring washers, and one mini wrench. The kit suits DIY repairs, 3D printers, electronics, RC models, and CNC machinery. All components are made from 304 stainless steel for corrosion resistance and high hardness. The compartmentalised case keeps parts labelled and accessible.

M3-0.5 Thread Pitch with Eight Lengths

The bolts share a standard M3-0.5 pitch and come in eight lengths: 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, and 30mm. Average dimensional error is less than 0.01mm, ensuring consistent fit for routine installations. This single thread specification decides whether the kit matches existing tapped holes or nuts in a project. Builders needing a different pitch or diameter must look elsewhere.

180 Pieces Per Component Type

Each of the four hardware types supplies 180 pieces, giving ample stock for multiple assemblies or repeated maintenance. The range of bolt lengths covers shallow to deep fastening needs up to 30mm. Projects requiring longer bolts, larger diameters such as M4 or M5, or different head styles will exceed this kit's capacity. The included mini wrench handles the supplied hex socket heads only.

Questions about this item

How many M3 screws, nuts and washers does the 720-piece kit actually give me for a 3D printer build?

The kit supplies 180 socket-head cap screws, 180 hex nuts, 180 flat washers and 180 spring washers, all M3-0.5 thread.

What does the M3-0.5 pitch mean when I am tapping or matching existing holes?

It means each turn advances the bolt 0.5 mm, the standard coarse pitch for M3, so it fits any M3-0.5 tapped hole or nut.

Will the compartmentalised case and the longest 30 mm bolts fit inside my printer’s maintenance drawer?

The case holds all 720 pieces in labelled compartments; the longest bolts are 30 mm, so measure your drawer depth against that length.
