Product and purpose
The Midwest Fastener 69325 is a pack of ten blind nut inserts with 1/4"-20 threads. These rivet nuts create strong, load-bearing threads in thin sheet metal, plastic or composite panels where only one side is accessible. They suit automotive repair, fabrication and maintenance jobs that need a reliable female thread without welding or access to the back face.
Build and installation
Each insert is made from steel for strength and wear resistance. The one-piece tubular body is counterbored and internally threaded, allowing it to be set with a rivet-nut tool that pulls the mandrel and expands the shank against the blind side of the workpiece. The result is a flush or near-flush anchor that resists pull-out and rotation during repeated bolt removal and reinstallation.
Compatibility checks
Verify that the base material thickness falls within the grip range of the insert you are using so the shank can fully collapse and clamp. Confirm the hole diameter matches the specified drill size for a 1/4"-20 rivet nut to avoid loose fits or installation damage. Ensure you have a suitable setting tool — manual, pneumatic or battery-powered — capable of pulling 1/4"-20 inserts before starting the job.

Questions about this item
What thread size does the 1/4"-20 blind nut insert use?
The insert has a 1/4"-20 thread size, meaning a quarter-inch diameter with twenty threads per inch for standard coarse threading.
What material and quantity come in the 69325 pack?
The pack contains ten steel blind nut inserts, each designed for one-sided installation in metal, plastic or fibreglass panels.
Which tool is needed to set these rivet nuts correctly?
A rivet-nut setter or hand tool that pulls the mandrel to collapse the body is required; the common mistake is using a standard rivet gun, which will not form the threads.
