YEEZET 652PCS Grade 8.8 M4 M5 M6 Heavy Duty Bolts and Nuts Assortment

In this review of the YEEZET 652PCS Grade 8.8 M4 M5 M6 assortment kit the bottom line is simple: this set is for craftsmen, maintenance technicians, and hobbyists who need a durable, wide-ranging fastener selection in one organized box. The reviewer found the most compelling reason to buy is the combination of 8.8 grade alloy steel construction and a practical plastic heat-seal storage box, which together deliver reliability and convenient organization for routine repairs and workshop projects.

Key Features

• Grade 8.8 alloy steel: Offers high hardness and strength that hold up under heavy loads and abrasive conditions.
• Corrosion-resistant finish: Helps the bolts and nuts resist rust and remain serviceable in tougher environments.
• Comprehensive size selection: Includes 13 common sizes so users can handle most small- to medium-duty fastening tasks without buying parts individually.
• Standardized tolerances: Threads and head placement meet tight size tolerances for consistent fit and reduced risk of slippage.
• Plastic heat-seal packaging: A sturdy compartment box keeps sets separated and easy to grab at the workbench.
• Obvious screw threads: Clean, well-formed threads make assembly smoother and reduce cross-threading.

Who It's For

The kit suits home mechanics, small workshop owners, and maintenance staff who frequently replace or stock common metric fasteners for appliances, furniture, or light machinery. The range of M4, M5 and M6 lengths covers many typical repair scenarios without needing custom runs or single-item purchases.

It is less appropriate for heavy industrial applications demanding higher grades than 8.8 or specialized coatings for extreme corrosion environments, and professionals who require uncommon sizes outside the 13 listed should look for a more tailored assortment.

Pros & Cons

Pros

• Durable 8.8 grade alloy steel construction that balances wear resistance and strength.
• Wide variety with 13 common sizes so fewer trips to the hardware store are needed.
• Neat plastic heat-seal packaging that keeps parts organized and portable.

Cons

• Not intended for very high-strength structural work where higher grade fasteners are required.
