1320Pcs Nuts and Bolts Assortment Kit - SAE Grade 8 Hardware Set

In this review of the 1320Pcs Nuts and Bolts Assortment Kit the bottom line is straightforward: this kit is for DIYers, mechanics and shop owners who need a broad selection of heavy-duty SAE hardware in one organized case. The reviewer found the most compelling reason to buy is the combination of SAE Grade 8 alloy steel fasteners and a rugged steel tray that keeps sizes sorted and protected, which saves time on common repairs and builds. It is presented as a ready-to-use solution for regular maintenance and projects rather than a single-use specialty pack.

Key Features

• Complete 1320-piece set: Includes 330 hex bolts, 330 hex nuts, 330 flat washers and 330 lock washers to cover a wide range of common fastener needs without frequent restocking.
• SAE Grade 8 alloy steel: The bolts, nuts and washers are made of high-quality alloy steel that stands up to demanding mechanical and automotive tasks.
• Multiple sizes: Sizes cover 1/4-20, 5/16-18, 3/8-16 and 1/2-13 with lengths from 3/4' to 2-1/2' so users can match fasteners to common thicknesses and assemblies.
• Rugged packaging: A heavy-duty locking 28-hole steel tray with labeled compartments measures 14.8in x 2in x 11.1in and secures hardware for transport and storage.
• Included mounting tools: The kit ships with one Y-wrench and four drill bits so users can start work immediately without searching for drivers.

Who It's For

This kit is aimed at home mechanics, small repair shops and hobbyists who need a durable, broad selection of hex bolts and nuts for machinery, furniture assembly, automotive and motorcycle maintenance. It suits people who prefer to have multiple sizes on hand rather than waiting for individual parts.

It is less ideal for specialists who require metric sizes or certified high-tolerance fasteners for aerospace or critical structural work; those buyers should look for purpose-built, certified fasteners. For general repair and DIY, though, this kit covers most common SAE needs.

Pros & Cons

Pros

• High hardness SAE Grade 8 alloy steel gives better wear resistance than generic hardware.
• Large quantity and variety reduce trips to the store and speed up repair jobs.
• Sturdy, labeled steel tray keeps parts organized and protected in a workbench or van.

Cons

• Contains only SAE sizes, so metric users will need a separate kit or converters.
• Value perception is mixed among some buyers comparing price to smaller, specialized packs.
