160 helicoil screw thread repair insert 1/4 - 28 x 7/16
160 HELICOIL SCREW THREAD REPAIR INSERT 1/4-28
This listing is for 160 new inserts. Each insert is thread size 1/4"-28 fine thread and measures approx 7/16" un-installed in length. 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.
