966-Piece Metric Bolt & Nut Kit — Grade 8.8 Hex Bolts & Nuts

Product description

This metric hex bolt, nut and washer kit is manufactured from alloy steel rated at class 8.8 and finished with a gold zinc (galvanized) coating to improve corrosion resistance and surface wear life. The set is suited for demanding tasks where stronger fasteners are required.

The assortment covers 19 length variations across four thread sizes: M4 x 12mm, 16mm, 20mm, 25mm, 30mm; M5 x 12mm, 16mm, 20mm, 25mm, 30mm; M6 x 12mm, 16mm, 20mm, 25mm, 30mm; and M8 x 16mm, 20mm, 25mm, 30mm. Alongside the hex head bolts and corresponding hex nuts, the kit contains both flat washers and spring lock washers to help secure joints.

The golden zinc plating provides an extra barrier against rust and environmental damage, helping maintain the fasteners’ appearance and mechanical reliability over time. The 8.8 grade alloy substrate delivers substantially higher tensile strength than common low-grade alternatives.

All components come organized in a durable, transparent case with individual compartments so sizes stay separated and visible. The compact, hand-carry box is designed for portability and makes the assortment convenient to bring to jobs or to keep with a home toolbox.

This 966-piece classification is suitable for a broad range of uses: mechanical and electronic equipment, furniture assembly, construction tasks, general machinery repairs, motorcycle and automotive maintenance, and many DIY projects where metric hardware is required.

Pros

  • High-strength grade 8.8 alloy steel
  • Extensive range of metric sizes
  • Clear compartment case for quick selection

Cons

  • Case compartments are somewhat compact
  • Doesn't include every possible length
  • Nuts and washers packaged separately in bags

VerdictSolid, heavy-duty hardware selection for general repairs and projects. The high-strength 8.8 alloy construction and golden zinc finish give corrosion resistance and durability, while the wide range of metric sizes and included washers make this a useful kit for home, workshop, and hobby use. The clear compartment case keeps parts visible and portable, though serious shops may still need a few spec

  6. Thomas J. 5/5

    Quick thanks

    Good screws

  7. Jeffrey Steencken 5/5

    Good but not exhaustive

    Useful for the workshop but it won't cover every length. Good for common repairs, though you'll still need to buy some odd sizes.

  8. shopaholic 5/5

    Handy sizes

    Nice mix of screws — useful for my 3D prints.

  9. bobwhitebarry 5/5

    Great value and functionality

    Convenient case and far cheaper than purchasing bolts individually. Quality appears solid.

  10. Indiana Joe 4/5

    Good kit but case limits use

    Great selection for the money, but the case compartments are tight. Nuts and washers arrive in tiny bags so when emptied together they can be hard to separate.
