* Follow the manual and use only tiny amounts of Loctite 262 around the bottom end of the rivnut before inserting. The substance is etching and will eat away primer on touch.

Use several strong fender washers and two small washers to support the nutsert towards the punch tool. Use either an 8-32 bolt to secure the rivnut to the punch tool or a headless stainless steel 8-32 threaded rod with a hex insert.<br>[[File:2022-09-04 16-18-41.jpg|500x500px]]<br>[[File:2022-09-04 | *You need a nutsert tool to place the nuts into the bottom skin, e.g. [https://www.pegasusautoracing.com/productdetails.asp?RecID=9698 this tool] with this adapter [https://www.aircraftspruce.com/catalog/pnpages/04-01427.php 8-32].<br>If you have a hydraulic knockout punch tool [https://www.amazon.com/gp/product/B07RT8RKQL e.g. this one from Amazon], you can make an adapter for pulling rivnuts by taking a 2 inch piece of a 3/4 steel rod, cutting a 3/4-16 male thread onto one end and an 8-32 female thread onto the other.
