Dorman 963-258BX is a metric rivet nut for adding a threaded insert when the back side of the work surface cannot be reached. Its M4-0.7 thread size suits repair and fabrication jobs that need a compact 4 mm threaded anchor, while steel construction with a yellow zinc coating gives the insert a durable base for service work.
