![]() 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.

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. Want to save time on shipping?
