FOLIV 318pcs Grade 8 Nuts and Bolts Assortment Kit - Heavy Duty Repair

In this review of the FOLIV 318pcs Grade 8 Nuts and Bolts Assortment Kit, the bottom line is simple: this kit is designed for hands-on users who need a reliable, high-hardness selection of SAE fasteners for maintenance or DIY projects. The biggest reason to buy is the Grade 8 alloy steel construction, which offers notable corrosion resistance and wear resistance compared with ordinary hardware, making it a sensible backup or repair set for mechanics, hobbyists and workshop owners.

Key Features

• Grade 8 alloy steel: Provides higher hardness and improved wear resistance for demanding repairs and mechanical use.
• Practical SAE sizes: Covers common fractional sizes from 1/4-20 to 3/8-16 across multiple lengths so users can pick the right bolt for furniture, machinery or vehicle tasks.
• Comprehensive assortment: Includes 117 hex bolts, 80 hex nuts and 80 spring washers (318 total) so you have matching hardware on hand without buying pieces separately.
• Professional labeled package: Parts are stored in a transparent compartment box with clear labels to prevent sizes from mixing and to speed selection on the job.
• Wide application range: Suited for car and motorcycle repair, furniture assembly, machinery maintenance and general DIY projects around the shop or garage.

Who It's For

This kit is best for DIYers, home mechanics and small workshop owners who want a durable set of SAE fasteners for repairs and spare parts. The Grade 8 construction is appropriate where higher hardness and corrosion resistance matter, such as light mechanical loads, assemblies that see wear, or projects that need long-lasting hardware.

It is less suited to users who need metric sizes, very large structural bolts, or those who require specialty coatings for extreme corrosion environments; professionals needing custom lengths or certified fasteners for critical structural work should look elsewhere.
