E-z Lok TH-132-SV Brass Threaded Insert 10-32 Unf

Product Description

The E-Z LOK TH-132-SV is a single-vane, tapered-hole threaded insert machined from brass and designed to install into plastic components. It creates a durable, load-bearing 10-32 UNF threaded hole in materials that cannot reliably hold a direct-tapped thread. The tapered hole design requires a stepped or tapered drill preparation, and the single vane locks the insert against rotation once pressed into place. Key dimensions are 0.296 inches insert diameter, 0.272 inches pilot diameter, and 0.225 inches overall length. Minimum wall thickness required in the host material is 0.159 inches. This insert is sized and toleranced to the inch measurement system.

This insert is intended for use in plastic assemblies where a permanent, precision internal thread is needed. Typical applications include injection-molded enclosures, housings, and structural plastic components that require repeated fastening with a 10-32 machine screw. The tapered hole preparation accepts small-end hole diameters of 0.267 inches and large-end hole diameters of 0.277 inches, allowing controlled press or thermal installation depending on the host plastic type. It is commonly used in electronics enclosures, instrumentation housings, and light-duty mechanical assemblies.

Key Features

• Brass construction provides corrosion resistance and reliable thread integrity in plastic host materials
• 10-32 UNF internal thread for standard machine screw compatibility
• Tapered hole design with 0.267 inches small-end and 0.277 inches large-end hole diameter for secure seating
• Single-vane locking geometry resists rotation after installation
• 0.225 inches overall length suits thin-wall plastic applications with 0.159 inches minimum wall thickness
• Inch measurement system; compatible with UNF fastener standards

Compatibility

Designed for installation into plastic host materials as an OEM-style threaded insert. Requires a tapered hole preparation with a small-end diameter of 0.267 inches and a large-end diameter of 0.277 inches.

Installation Notes

Installation is performed by pressing or thermally driving the insert into a properly prepared tapered hole in the plastic workpiece. Power down any associated equipment and secure the workpiece before installation. Use an appropriate press, arbor, or thermal insertion tool sized for the 0.296 inch insert diameter to avoid cracking the host material. Do not attempt to drive the insert with impact tools, as this may damage the vane or deform the host.
