In this review the FOLIV 772PCS Grade 8 Bolt Assortment Kit is assessed for mechanics, hobbyists and home DIYers who need a heavy duty SAE bolt collection. The bottom line: this kit is most valuable for anyone who wants a robust, ready-to-use set of Grade 8 bolts that includes matching nuts and spring washers, all stored in an upgraded double-side 30 compartment box. Reviewers will appreciate the broad SAE size range and the fact that the kit aims to remove the need to buy additional fasteners or organizers.

Key Features

• Grade 8 alloy steel: The bolts are made from heavy duty Grade 8 material for higher hardness and wear resistance when compared with standard hardware.
• Complete SAE assortment: The kit covers 1/4-20, 5/16-18, 3/8-16 and 1/2-13 sizes with multiple lengths so users can tackle a variety of repairs without searching for individual parts.
• Full fastener sets included: The package supplies 193 hex bolts, 193 hex nuts and 193 spring washers so you do not need to source complementary hardware separately.
• Upgraded sturdy case: The double-side 30 compartment box offers stronger construction and larger capacity to keep the heavy bolts organized and easy to carry.
• Corrosion resistance: The alloy finish provides improved resistance to corrosion for longer service life in workshop and vehicle environments.

Who It's For

The kit is best suited for professional mechanics, garage owners and serious DIYers who work on machinery, furniture, cars or motorcycles and want a ready assortment of heavy duty SAE bolts and matching hardware. The inclusion of nuts and spring washers and the sturdy organizer case make it especially useful for mobile technicians and small shops that need portable, pre-sorted fasteners.

Those who should look elsewhere include users who only need metric sizes or who require specialty head types beyond hex bolts. If you only need a few specific bolts for occasional household tasks, this 772 piece heavy kit may be more capacity than necessary.
