E-z Lok 329-1614 Thread Locking Insert Uns Self-lock Wall

Product Description

The E-Z LOK 329-1614 is a self-locking threaded insert designed to create a secure, permanent internal thread in a parent material. With a 1-14 internal thread and a 1-3/8-12 external thread, this UNS insert installs using a standard tap and locks into the host material via a self-lock wall design. Manufactured from C12L14 carbon steel with a smooth, rolled finish, it provides reliable thread repair or thread conversion in metal assemblies. Overall length is 1.25 inches. Machinists, maintenance technicians, and assembly professionals install this type of insert in industrial, mechanical, and OEM applications.

This insert suits applications requiring a robust internal thread in steel or similar base materials where the external thread size differs from the desired internal thread specification. The self-lock wall design resists loosening under vibration and torque loads, making it appropriate for high-stress mechanical assemblies. Typical scenarios include thread repair on worn bores, thread-size conversion in machined components, and OEM production assembly where precise thread engagement is critical. Installation requires a standard tap preparation of the parent bore.

Key Features

• 1-14 internal thread with Class 2B fit for reliable fastener engagement
• 1-3/8-12 external thread with Class 2A fit for controlled installation torque
• Self-lock wall design resists rotation and pull-out under load
• C12L14 carbon steel construction for strength in metal assemblies
• UNS thread standard with smooth, rolled finish for consistent thread form
• 1.25-inch overall length suits deeper engagement requirements

Compatibility

Designed as an OEM-style threaded insert for metal parent materials prepared with a standard tap to accept a 1-3/8-12 external thread profile.

Installation Notes

Installation is typically performed by a machinist or qualified maintenance technician. The parent bore must be tapped to the correct external thread specification using a standard tap before the insert is driven in. Secure the workpiece and ensure the bore is clean and free of debris prior to installation. Follow applicable shop safety procedures and consult the insert manufacturer guidelines for proper installation tooling.
