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.

Frequently Asked Questions

Q. What is the significance of open-ended self-locking inserts?

A. Inserts having an open end allow installation of fasteners longer than the inserts.

Q. What are some compatible accessories used with these self-locking inserts?

A. Raptor Supplies offers compatible insert tools like drill bits, standard taps, bolts with two nuts and installation bits for installing these inserts.

Q. How to install a self-locking insert?

A.

  • Drill a hole according to the insert length & diameter using a standard drill.
  • Tap the drilled hole using a standard tap of the desired thread size.
  • Wind the insert into the hole like an ordinary fastener using a screwdriver, bolt & jam nut or an optional E-Z LOK drive tool.
  • 5 minutes after the threaded insert is placed in the hole, the pre-applied Loctite adhesive on the external threads starts setting for installing the fastener in minutes. After fully curing (72 hours), they can seal against liquids or gases having pressure up to 6000 psi.

Q. Can we reuse these inserts once removed?

A. The external thread adhesive of these inserts starts setting after installation. Users can install a bolt inside it only if they do not want to remove it in future. Removing the bolt from the insert & the insert from the material after installation may destroy the adhesive & hence the insert's effectiveness. So, users can not reuse these inserts once removed from the application surface.
