Which fastener is used for inaccessible locations and riveted into place?

• A. Plate Nut
• B. Nuts
• C. Rivet
• D. Castellated

Answer: (A)

When you need a threaded attachment in a location you can’t reach from the other side, a plate nut is the right choice. It’s a nut mounted on a small base plate that can be riveted to the surface, permanently securing the threaded hole in place. This lets you bolt parts together from the accessible side even when the area behind is inaccessible. The other options don’t fit as well: a plain nut isn’t riveted in place and typically requires access to the back to hold it; a rivet is a fastener used to join materials and doesn’t provide a threaded hole for a bolt; a castellated nut is a locking nut used with a cotter pin and isn’t about installing a nut in a difficult-to-reach location.
