Threaded Inserts Now Available From Hardware.aero!

Hardware.aero is pleased to announce that we have expanded our catalog by adding threaded inserts to the collection. 

What is a Threaded Insert?

Threaded inserts are used to prevent stripping in a softer material or to repair material where the threading has been damaged.  The insert is literally inserted into the hole to provide threading for a screw or stud to utilize.  They are a relatively inexpensive solution to protect your machined metal parts.

These are the primary types of threaded inserts we will discuss:

• Helical wire -- literally wire that is coil-formed to the designated thread size.  This comes either tanged or tangless.
• Keylocking Threaded Inserts -- this type features a solid, one-piece construction utilizing "keys" which are tapped into place to lock position

Who are the common manufacturers of Threaded Inserts for aerospace?

• Arconic Fastening Systems (aka Alcoa aka Fairchild aka Keensert aka Recoil)
