125 helicoil screw thread repair insert 1/4 -28 x 5/8"
125 HELICOIL SCREW THREAD REPAIR INSERT 1/4" - 28 x +5/8"
This listing is for 125 new inserts. Each is threaded 1/4" - 28 and is approx +5/8" in un-installed length long. 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.
