## Description

The M3 size and 304 stainless steel construction make this assortment a practical source of fasteners for repairs and assembly work. It brings together socket head cap screws, nuts, and washers in a single organized kit.

Seven screw lengths—from M3 x 4mm to M3 x 20mm—make it easier to select a fastener to suit different assembly depths. The assortment also includes flat and lock washers for a range of fastening setups.

A compartmented storage box keeps the different sizes sorted and labeled, so you can find the right parts for a repair or project and put the remaining pieces away in an orderly way.

## Quick sizing guide

Choose from M3 screw lengths of 4mm, 6mm, 8mm, 10mm, 12mm, 16mm, and 20mm. Each length has its own labeled compartment, making it easier to compare options and select a screw based on the space and material being fastened. The set uses an M3-0.5 thread size, so match that thread specification when replacing a fastener or combining components.

For example, when a small appliance or precision instrument needs a replacement screw, the range of lengths gives you several M3 options in one kit rather than a single fixed length. A hex wrench is used to drive the screws, the wrench is not included.

## Pros

The 566-piece assortment combines screws, M3 hex nuts, flat washers, and lock washers for common fastening and repair tasks. The 304 stainless steel construction is described as offering corrosion resistance, a useful consideration for parts exposed to moisture or changing conditions. Its plain silver finish also makes the fasteners easy to identify in an assembly.

Instead of purchasing one screw size at a time, this kit provides seven lengths alongside the matching nuts and washers. That format is useful for keeping replacement hardware available for precision machinery, electronics, home appliances, printers, lamps, toys, and other equipment that uses M3 fasteners. Buyers have also highlighted the set’s functionality and value for its intended use.
