Hex Drive Thread Inserts

• Flanged hex drive threaded inserts are installed up to the lip near the head of the insert whereas flush hex drive threaded inserts do not have a lip near the head and can be installed either completely flush with the surface or a little countersunk.
• Flanged hex drive threaded inserts are referred to as Type D insert nuts while flush inserts are referred to as Type E insert nuts.

• Threaded inserts offer a stronger alternative to tapped holes & weld nuts and provide a stronger bond than self-tapping screws.
• They are usually the least time-consuming and strongest fasteners used in any manufacturing setting.

In many cases, hex drive thread inserts can be removed using special extraction tools and reused if they are in good condition. However, the success of removal and reuse depends on factors such as the type of material, installation method and extent of wear.

Hex drive thread inserts are installed by threading them into a pre-drilled hole using a hex key or driver. As the insert is turned into the hole, its external threads cut into the surrounding material, creating strong internal threads that securely hold screws or bolts.
