Specialinsert 307 Self-tapping Insert, 10-24 .295″ OD X .275″ L, Steel

Description

The Specialinsert 307 is a self-tapping threaded insert sized for 10-24 thread, with a 0.295 inch outer diameter and 0.275 inch length, built to cut its own internal thread into plastic or light metal as it drives in. Because the insert is self-tapping rather than requiring a separate thread-forming step, it also cuts assembly time on production runs where every extra operation adds cost across thousands of units.

How this self-tapping threaded insert saves a step

A standard threaded insert needs a pre-tapped hole ready to receive it before installation. The 307 skips that step entirely. Its self-tapping design cuts thread into the host material as the insert is driven home, so installers go straight from a plain drilled hole to a finished metal thread with one tool and one motion. That single-step install is why the 307 shows up on production lines and repair benches that need to add a durable, reusable metal thread to plastic housings, panels, or light-gauge parts without a separate tapping operation slowing the line down.

Installation and where a self-tapping threaded insert like this fits

The 307 drives in quickly with a cordless drill and a suitable driver bit, no dedicated setting tool required, which keeps it practical for field repairs as well as bench assembly. Once seated, it leaves behind a load-bearing metal thread that stands up to repeated bolt-and-unbolt cycles far better than threading directly into bare plastic, where the plastic’s own threads wear out and strip after a handful of cycles. That makes it a good fit anywhere a plastic enclosure, bracket, or housing needs a metal-strength mounting point: electronics housings, light fixtures, panel assemblies, and general equipment enclosures that get opened and closed repeatedly for service. It also works well as a service-friendly upgrade on equipment that gets serviced often, since a metal-threaded mounting point tolerates far more removal-and-reinstall cycles than the surrounding plastic ever could on its own.
