Value Collection BDC690612 Thread Locking Insert Unc

Product Description

The VALUE COLLECTION BDC690612 is a thread locking insert designed for thread repair applications in carbon steel construction. It accepts a 1/2-13 internal thread and installs into a 3/4-10 external thread, both in UNC (Unified National Coarse) standard. The overall length is 0.656 inches. This insert restores damaged or stripped threaded holes to their original specification, allowing fasteners to engage securely without replacing the entire workpiece. It is commonly installed by machinists, maintenance technicians, and mechanical contractors working on equipment repair, fixture rebuilding, or field service tasks where thread integrity must be restored quickly and reliably.

Thread locking inserts of this type are used across a broad range of industrial, mechanical, and field maintenance applications. Typical scenarios include repairing stripped bolt holes in machinery housings, structural assemblies, and equipment frames. The 1/2-13 internal thread accepts standard UNC fasteners, while the 3/4-10 external thread anchors the insert into an appropriately tapped hole. This insert is suited for both shop and field use wherever carbon steel hardware is specified.

Key Features

• 1/2-13 internal thread accepts standard UNC fasteners after installation
• 3/4-10 external thread for secure anchoring into the repair hole
• 0.656-inch overall length provides adequate thread engagement depth
• Carbon steel construction with bright finish for durability in mechanical applications
• UNC thread standard for broad fastener compatibility
• Sold in a package of 5 inserts

Compatibility

Designed as an OEM-style thread repair insert for applications requiring a 1/2-13 internal thread and a 3/4-10 UNC external thread in carbon steel assemblies.

Installation Notes

Thread locking inserts are typically installed by machinists or qualified mechanical technicians. Before installation, de-energize and lock out any equipment being serviced per applicable safety procedures. The receiving hole must be drilled and tapped to the correct 3/4-10 UNC specification before the insert is driven or pressed into place. Verify thread engagement and insert seating before returning fasteners to service.
