## Description

When a repair calls for different metric fasteners, having several sizes and matching washers to hand can make assembly more straightforward. This huruirui set brings together M3, M4, M5 and M6 bolts, nuts and washers in one organised kit.

The fasteners are made from stainless steel 304, with hex heads and a glossy finish. For home repairs, furniture work, bicycle maintenance or a 3D printing project, the range gives you common thread sizes in one place. Which sizes will suit your job? Match the M3–M6 thread size and the required bolt length to the parts you are joining.

## Fit and sizing

The assortment covers four metric thread sizes: M3, M4, M5 and M6. It contains 520 pieces in total: 120 bolts, 120 nuts, 140 locking washers and 140 flat washers. The listed bolt lengths include 10 mm, 20 mm and 30 mm options for M3, M4 and M5, with several lengths listed for M6. This mix is useful when a project involves different fastening points or you want matching nuts and washers close at hand.

A practical example is a small furniture repair: identify the thread size and length needed for the joint, then use the matching nut and washer as part of the assembly. The metric sizes also make the kit relevant to maintenance and workshop tasks where M3–M6 fasteners are required.

## Why it makes sense

Rather than buying a single size for each task, this assortment keeps several commonly used sizes together. Stainless steel 304 is specified for the fasteners, and the source describes the material as corrosion-resistant, making the set suitable for indoor and outdoor applications. Hex heads provide a recognisable fastening style for assembly work, while the nuts and flat or locking washers help complete a joined connection.

The pieces are arranged in a storage box with labels to help you find a size more quickly. Buyers value the range of small fasteners and the convenience of keeping them together for home or workshop jobs. Feedback on the case’s durability is mixed, with some buyers mentioning issues with its plastic hinges, so handle the box with care when organising or transporting the pieces.
