E-z Lok 319-7 Thread Locking Insert 7/16-14 Unc Self-lock Wall

Product Description

The E-Z LOK 319-7 is a self-locking threaded insert designed to create strong, vibration-resistant internal threads in parent materials. It features a 7/16-14 UNC internal thread and a 9/16-12 UNC external thread, with an overall length of 0.56 inches. Manufactured from C12L14 carbon steel with a smooth, rolled finish, this insert delivers a tensile strength of 15,587 pounds. It is installed using a standard tap and is suited for applications where thread pullout resistance and locking retention are critical. Licensed HVAC, mechanical, and industrial technicians commonly use these inserts in metal fabrication and equipment assembly work.

This self-lock wall insert is appropriate for use in metal assemblies requiring a secure threaded connection that resists loosening under vibration or cyclical loading. The UNC thread standard makes it compatible with standard inch-series fastener systems. Typical installations include HVAC equipment frames, electrical enclosures, pump housings, and other fabricated metal components where tapped parent material threads are insufficient or have been damaged and need repair.

Key Features

• 7/16-14 UNC internal thread with 2B class of fit for precise fastener engagement
• 9/16-12 UNC external thread with 2A class of fit for secure host material installation
• C12L14 carbon steel construction with smooth, rolled finish for consistent installation torque
• Tensile strength of 15,587 pounds for high-load thread retention
• Self-lock wall design resists loosening under vibration without additional locking hardware
• Installs with a standard tap - no proprietary tooling required

Compatibility

Designed as an OEM-style threaded insert for use in standard UNC inch-series thread applications where a self-locking, high-strength internal thread is required in carbon steel or similar base materials.

Installation Notes

Installation is performed by threading and mechanical tradespeople familiar with insert installation procedures. The parent material must be properly tapped using a standard tap before the insert is driven in. Ensure the bore is clean and free of debris before installation. Always verify thread engagement and torque specifications against the equipment manufacturer's service documentation before final assembly.
