The best stainless steel rivet nut kit depends on your thread standards, size range, and whether you need an installation tool. The 220-piece Vifmy SAE kit suits projects using common inch threads, while the 300-piece Vifmy assortment covers both SAE and metric sizes. For a kit that includes a manual tool, consider the 560-piece AskWay set. The Glarks assortment is a metric option, and the other 220-piece assortment is another SAE-focused choice.

Vifmy 220-Piece SAE Stainless Steel Kit
This kit contains 220 flat-head SAE rivet nuts in five thread sizes: #8-32, #10-24, 1/4″-20, 5/16″-18, and 3/8″-16. The listed material is 304 (18-8) stainless steel, described as corrosion resistant. Its flat, deep threads and flat-head design are intended to support fastening and resist slipping.
Best for: DIYers and repair workers who use SAE threads and want several common sizes in one assortment. It is a focused choice for projects that do not require metric fasteners. Limitation: The kit is SAE-only, and the product details do not list an installation tool.
Vifmy 300-Piece SAE and Metric Kit
This assortment includes 172 metric rivet nuts and 128 SAE rivet nuts. Metric sizes range from M3 to M12, while SAE sizes range from #8-32 to 3/8″-16. The size spread can help users keep both measurement systems available for different repairs or builds.
Best for: Buyers who work on projects with a mix of metric and inch-thread hardware. Choose this if thread variety matters more than having an installation tool in the same kit. Limitation: The supplied product information does not specify the stainless steel grade or include a tool, so verify material and tool requirements before buying.
AskWay 560-Piece Kit With Manual Tool
The AskWay set combines a manual rivet nut tool with 560 listed 304 stainless steel rivet nuts in eight metric and SAE thread sizes. The assortment includes M3, M4, M5, M6, 6-32, 8-32, 10-24, and 1/4″-20. The product description also notes a knurled flat-head design intended to help prevent slipping.
Best for: Buyers who need an assortment and a manual tool in one purchase, especially for household, furniture, automotive, or sheet-metal work. Limitation: Its listed size range does not include larger sizes such as M8, M10, or 3/8″-16, so check the job’s thread specification first.
220-Piece SAE Rivet Nut Assortment
The product name identifies this as a 220-piece stainless steel SAE assortment covering #8-32, #10-24, 1/4″-20, 5/16″-18, and 3/8″-16. Those five sizes make it a direct match for jobs that need common inch-thread rivet nuts rather than metric options.
Best for: Buyers looking for a basic SAE assortment with the listed five-size range. Limitation: The supplied listing data does not provide a piece count by size, steel grade, installation tool information, or other design details. Confirm those specifics if they affect your project.
Glarks 180-Piece Metric Rivet Nut Kit
This 180-piece kit is described as a stainless steel flat-head assortment with six metric sizes: M3, M4, M5, M6, M8, and M10. The product name identifies automotive, furniture, and home-appliance applications, making it a metric-focused option for repairs and assembly work.
Best for: Buyers who need metric rivet nuts across small and mid-size threads, including M8 and M10. Limitation: The provided details do not state how many pieces are included in each size or specify the stainless steel grade. It is not an SAE assortment.
Buying Guide: How to Choose Stainless Steel Rivet Nuts
Do you need SAE or metric threads?
Match the rivet nut’s internal thread to the bolt or screw you plan to use. SAE sizes such as 1/4″-20 and #10-24 are not interchangeable with metric sizes such as M6 or M8. If your projects use both standards, a dual-standard assortment can reduce the need to source a second kit.
Which sizes and quantities will your projects use?
Check the exact thread sizes before choosing by total piece count. A larger assortment may still omit the size you need, while a smaller kit may provide a more relevant range. For repeat work, check the listed quantity for each size so you can assess whether the assortment suits expected usage.
Is an installation tool included?
Rivet nuts need to be set in a prepared hole, and the AskWay product listing specifically includes a manual tool. The other kits described here do not list a tool in the supplied product details. If you already own a compatible setting tool, an assortment-only kit may be sufficient; otherwise, verify what is included.
What should you check about stainless steel?
Stainless steel can be useful where corrosion resistance is a consideration, but product grades and details differ. The Vifmy 220-piece SAE kit and AskWay kit specifically identify 304 stainless steel. For products whose supplied details do not name a grade, check the listing before relying on a specific material specification.
Frequently Asked Questions
What is a rivet nut used for?
A rivet nut creates an internally threaded fastening point in a material where a conventional nut may be difficult to reach or hold during assembly.
Can SAE and metric rivet nuts be used interchangeably?
No. SAE and metric threads use different standards and dimensions. Select a rivet nut that matches the bolt or screw thread exactly.
Does stainless steel mean the rivet nut will never corrode?
No material should be treated as immune to every environment. Check the stated stainless steel grade and whether it suits the conditions of your project.
Do these kits include a rivet nut tool?
The AskWay listing specifies a manual tool. The supplied details for the other four assortments do not identify an included installation tool.
