34 HELICOIL SCREW THREAD REPAIR INSERT 1/2-20 x .875"
This listing is for 34 new inserts. Each insert is thread size 1/2-20 and measures .875" (7/8") long when threaded. Screw thread inserts are used when the original thread of a hole has been worn and is no longer useable. When they are installed into Heli-Coil tapped holes, they provide permanent conventional 60' internal screw threads that accommodate any standard bolt or screw.
