Description

Self-locking inserts are suitable for locking threaded fasteners inside a tapped hole in automobile, aerospace and maintenance applications. Raptor Supplies offers these thread-locking inserts from E-Z Lok. They lock the threads of the fastener and prevent their loosening due to vibration.

Features

  • E-Z LOK self-locking inserts create strong internal threading on metallic surfaces.
  • They are equipped with a pre-applied Loctite adhesive that activates after installation to offer a strong connection to the material & fastener while preventing wear or over-torque.
  • These inserts come with standard UNC / UNF / Metric threading on their external & internal surfaces for use with the respective drill / tap / fastener.
  • The external thread adhesive secures these inserts in the material's tapped hole.
  • The adhesive on the internal thread keeps the fasteners from backing out by locking them.
  • After fully curing the adhesive, these inserts can seal against liquid / gas pressure up to 6000 psi.
  • Grade 303 self-locking inserts are corrosion resistant and have a sleek & polished appearance.
  • Users can also drive these inserts with right-direction threads & a slotted drive using a slotted screwdriver instead of an installation bit.
  • Carbon steel self locking inserts can withstand high temperatures without losing their mechanical properties.
