Love the different sizes

In the United States metric bolts are much more expensive than standard (SAE). Was always annoying buying rivnut kits and having half that I'll likely never use.They come in a clear plastic case. I moved them into a packout that holds a small rivnut tool. Recommended if you need lots of standard rivnuts.

A nice selection of SAE rivet nuts to have on hand which can be used for multiple things, being especially useful in blindside applications. The plastic case they come in is really cheap and I don't see the hinges or latches lasting very long. Threads are mostly clean with only some slight burring. The anti-twist ribs on the shanks aren't as prominent as others, primarily on smaller sizes, so could be issues with slippage in softer material. The pictures on the ad indicate they are stainless, but they are in fact zinc plated steel (Note: the text description in the ad references material correctly). Also, not a big deal but the pictures show the label being under the lid, whereas mine is on the top of the lid so you can't see which size is which without closing and opening the lid.All in all this assortment of rivet nuts will be useful to have on hand, but there could be some improvements as described.

I needed some specific-size replacements after getting threaded furniture legs that unfortunately did not match the available slots on my (yup, discounted!) furniture from an auction.Then I remembered about the table I really wished was on casters...Then I remembered the wooden office chair that had a wobbly caster because of the insert, which wasn't going to un-insert and re-insert.Was shopping for a set of six plus the handful of oddballs locally and online but the math didn't add up considering the value you get with this set. I was considering it on Amazon when it popped up on Vine, so I was happy to have the chance to try it out for y'all.GOOD:*Plenty of inserts in common sizes so that you can fix your issues*Threads consistent and match casters/threaded rods fine. No cross-threads*Once you start fixing your insert-issues, you'll remember more you need to fix, and you'll have them with this set*Very sturdy - even an impatient repair person (not that I know any) won't smoosh theseISSUES:*Not really an issue, but the plastic box they came in was cracked on the corner. Wasn't an issue since the whole thing was bagged, and most likely happened because these are nice and heavy-weight. Piece of tape sealed it back up, no issues, and I fully expect to use most of these by the end of the year, so I'm not stressing on it. I'd rather get a really great value on some quality inserts I can use than to get flimsy ones that the lightweight container can hold. Definitely not deducting a star because the item itself being quality created an issue with the transport vessel! Will never complain about quality products.This will get lined up with my other trays of assorted hardware so they'll be easy to find and right at hand when I get a break in a few weeks and become a full-time (vacation week) repair person.Good value, good quality, and you're gonna use them out of the container pretty quickly anyway, so five stars!

I was pleased to locate this standard size Rivet Nut Kit.The plastic partitioned box makes storage and access to the pieces easy and keeps the rivet nuts organized.Rivet nuts make for a clean means of fastening to many metal surfaces where accessing the nut to tighten or loosen the bolt provides no accessibility for your hands and tools.The kit provides an ample number of pieces of each size.Rivet nuts are easy-to-install, reliable fasteners that can provide strong load-bearing threads into weak or thin gauge materials such as castings, housings, panels, tubes, and extrusions. Additionally, because of their wide grip range tolerance, rivet nuts can be installed into a variety of material thicknesses.These fasteners are designed to be automated and are used widely throughout the automotive industry to attach items to dashboards, as well as in the chassis and bodywork to connect roof racks, spoilers, plastic fenders, radiators, and more. Rivet nuts are also perfect for every stage of production with no reworking needed after insertion—even when the workpiece has already been coated or painted. Some other industries and applications: Refrigerators Playground equipment Office furniture Solar panel installation Medical technology Plastics engineering Electronics Bicycles Aerospace industry Military vehicles Boats Swimming poolsAmong the primary benefits of rivet nuts are that they offer a faster assembly and lower installation costs compared to other fasteners. Because rivet nuts are made to be automated and used in factory settings, power installation tools are often mounted to a six-axis robot. But for individual use, you can install rivet nuts using easy-to-operate and lightweight hand tools.
