So how do you deform it? It can be accomplished with a bolt and nut arrangement…but it’s far easier and cleaner to use a proper tool. When you examine a common rivet nut, you’ll see that it’s a rather robust piece, even though it is engineered to deform. Spend a few pennies more per rivet nut and you’ll be happy! (Image/Wayne Scraba) I had a couple of cheap “off brand” rivet nuts in my stash that refused to deform properly, no matter what tooling I used. ![]() Word of caution here: Not all rivet nuts are created equal. Depending upon the format, rivet nuts are available cad plated, zinc plated, or natural (plated steel being the most common). The purpose of ribbed flanges and ribbed bodies is to provide additional gripping strength for the completed fastener. ![]() In some cases, the backside of the flange is ribbed. The majority are equipped with thin flanges that surround the hole. In addition, some rivet nuts are aluminum. They’re also available in a wide range of thread sizes and pitches. Assembly access is only from one side (they install “blind”) and they’re immune to high temperature. They work well on thin wall components (for example, automotive sheet metal or even frame rails). These ingenious components are strong enough to create load bearing threads. I don’t have a lot of experience with these fasteners, because there is a better option: Enter the Rivet Nut (AKA “RivNut” or “NutSert”) Finally, there are some deforming metal and plastic products that work much like a household wall anchor. They’re simply good at fitting overlapping panels. The trouble with U-nuts is they’re not really blind nuts. U-nuts are another possibility, and they’re used with regularity in the automotive industry. The problem here is, the opening must be rather healthy in order to fit the apparatus. There are also some metal expansion nuts that pop into a hole. Yes, they work most of the time, but don’t expect them to hold heavy items. They expand behind the hole as you tighten the fastener and more or less seal the hole. Sure, you can use “well nuts” which are really expanding rubber nuts. ![]() GISON has been offering customers high-quality air tools and pneumatic hand tools, both with advanced technology and 50 years of experience, GISON ensures each customer's demands are met.Sometimes you’ll find a spot on your project where you need a nut to secure a fastener, but there’s no way to reach the back side of it for access.
