Metric & SAE Rivet Nut Assortment Kit (920 Pcs) - Complete Fastener

In this review the Metric & SAE Rivet Nut Assortment Kit is evaluated as a practical, all-in-one solution for hobbyists and professional installers who need a broad range of rivet nuts. The bottom line: it delivers a large, mixed selection of standard sizes and solid performance for general fastening tasks, making it a convenient kit to keep in a workshop or service van. The primary reason to buy is the sheer quantity and variety - 920 zinc plated carbon steel rivnuts in metric and SAE sizes - which covers most common repair and assembly needs.

Key Features

• Two-in-one assortment: Includes 460 metric and 460 SAE rivet nuts so users can tackle projects that require either standard system without separate purchases.
• Wide size range: Six metric sizes (M3 to M10) and six SAE sizes (#6-32 to 3/8'-16) provide coverage for light to medium duty fastening across many applications.
• Zinc plated carbon steel: The carbon steel construction with a zinc plated surface improves strength and offers corrosion resistance for longer service life.
• Flat head vertical thread design: Flat, deep threads give a secure hold and anti-slip effect when installed in thin materials or panels.
• Clear carrying case: Twelve individually stowed compartments make storage and selection easy and help prevent mixing of sizes during use.

Who It's For

The kit is ideal for home mechanics, furniture assemblers, appliance repair technicians, and hobbyists who need a ready supply of common rivet nut sizes for fastening into thin sheet metal or tubing. It suits anyone who values variety and wants both metric and SAE options in a single kit to avoid multiple trips for parts.

It is less suited for heavy industrial users who require high volume production-grade fasteners in specialty alloys or for those who need bespoke sizes beyond the six metric and six SAE options provided. If corrosion resistance in harsh environments is critical, a stainless steel alternative may be preferable.

Pros & Cons

Pros

• Large 920-piece count offers excellent value and reduces frequent reordering.
• Good selection of sizes across metric and SAE systems, making the kit versatile.
• Zinc plated carbon steel construction balances strength and corrosion resistance for general use.
• Organized clear case keeps sizes separated and portable for jobsite use.

Cons

• Case dividers can feel flimsy and may come loose with heavy handling, which a few customers noted.
• Not intended for high-corrosion or aerospace environments where stainless or specialty materials are required.

Our Verdict

The Metric & SAE Rivet Nut Assortment Kit is a practical, cost-effective option for most repair and light fabrication work because it bundles a wide range of sizes and solid zinc plated carbon steel hardware in a single, portable kit. It represents good value for DIYers, mechanics, and maintenance staff who need an organized selection of common rivet nuts, though heavy industrial users should consider premium alloys.

Frequently Asked Questions

Are these rivet nuts corrosion resistant?
They have a zinc plated finish over carbon steel which improves rust resistance for general use but is not as corrosion-proof as stainless steel in harsh environments.

Does the kit include both metric and SAE sizes?
Yes, the kit contains 460 metric rivet nuts and 460 SAE rivet nuts for a total of 920 pieces.

Are the sizes organized for easy access?
Yes, each of the 12 sizes is stored in its own compartment within a clear carrying case, though some users report the dividers can be a bit flimsy.
