Metric Screw Assortment Kit 3670pcs M2 M3 M4 M5 - Complete Bolt Set

In this review the weideer 3670pcs Metric Screw Assortment is assessed as a practical, no-frills hardware kit for hobbyists, small workshops and electronics tinkerers who need a broad range of metric fasteners on hand. The single biggest reason to buy is the sheer quantity and variety: 3670 pieces across 33 sizes, with both hex socket and hex button head machine screws plus matching nuts and washers, make it a convenient one-stop kit for repeat repairs and prototyping.

Key Features

• Large assortment: 3670pcs across 33 sizes provides a deep inventory so users rarely run out of common metric screws during a project.
• Dual head types: Includes 2000pcs hex socket head and 1670pcs hex button head screws to suit different fastener needs and aesthetic preferences.
• High strength materials: Machine screws are made of 12.9 and 10.9 alloy steel for stronger clamping and better durability in mechanical assemblies.
• Protective finish: Black zinc plating offers corrosion resistance so parts stay usable after storage or light outdoor exposure.
• Organized packaging: Screws are separated into compartments in a reusable box and come with wrenches and instructions for easier identification and use.

Who It's For

This kit is aimed at electronics hobbyists, model builders, small repair shops and anyone who frequently works on precision machinery, toys, appliances or automotive trim where metric fasteners are common. The mix of M2, M3, M4 and M5 sizes covers most small equipment and consumer electronics needs.

It is less suited for users who need imperial sizes, those who require only a few specialty fasteners, or professionals who demand factory-specified single-supplier parts; the box is broad in scope but not a certified replacement for OEM hardware in critical structural applications.

Pros & Cons

Pros

• Extensive quantity and size range means fewer trips to the hardware store for common metric screws.
• Combination of 12.9 and 10.9 alloy steel offers high strength suitable for many mechanical uses.
• Black zinc plating improves corrosion resistance and shelf life of the parts.
• Reusable, upgraded box with labeled compartments and included wrenches makes storage and selection straightforward.

Cons

• Some customers report the kit arrives mixed and requires sorting despite compartmental packaging, so initial setup can take time.
• Compartment sizes may not perfectly match every screw quantity, causing occasional overflow between slots.
