710Pcs Nuts and Bolts Assortment Kit, Metric Grade 10.9 - Durable

Our review of this 710pcs nuts and bolts assortment finds it best suited to DIYers, home mechanics, and small workshops who need a wide range of strong metric fasteners in one organized kit. The single biggest reason to buy is the combination of metric grade 10.9 alloy steel hardware and the heavy-duty steel tray that keeps 21 sizes clearly labeled and accessible, so replacing or matching bolts for furniture, automotive trim, or machinery repairs is straightforward.

Key Features

• High strength materials: Metric grade 10.9 alloy steel construction gives the bolts and nuts high tensile strength for demanding repair and assembly tasks.
• Zinc plated finish: Zinc plating provides practical corrosion and rust resistance so parts last longer in exposed or humid environments.
• Comprehensive size range: The kit covers M6, M8, M10 and M12 across multiple lengths, making it easy to find the right fastener without multiple trips to a store.
• Complete counts and organization: 248 hex bolts, 154 nuts, 154 washers and 154 lock washers are stored in a labeled 28-hole steel tray for rapid selection and secure transport.
• Included mounting tool: A Y-wrench plus four driver bits are provided so you can start using the kit immediately for common fastening tasks.

Who It's For

This kit is ideal for hobbyists, small repair shops, and vehicle owners who value having a broad selection of high-strength metric hardware on hand. The wide range of lengths and the organized steel tray mean you can tackle furniture assembly, motorcycle trim work, or general machinery maintenance without digging through mismatched fasteners.

Those who need specialty or aerospace-grade fasteners, stainless steel corrosion resistance for marine use, or exact OEM finishes should look elsewhere; this set focuses on strong alloy steel with zinc plating rather than specialty materials.
