E-z Lok 801420-20 Flush Hex Drive Insert 1/4-20 50 Pack

Product Description

The E-Z LOK 801420-20 is a flush hex drive threaded insert designed to create strong, permanent internal threads in soft materials such as wood, plastics, and composites. The insert accepts a 1/4-20 thread and is manufactured from zinc alloy, providing solid wear resistance in moderate-load fastening applications. It measures 0.7874 inches in overall length with an insert diameter of 0.453 inches and installs into a 23/64-inch (0.3543-inch) prepared hole. Drive installation requires an M6 hex key. This part is sold in a package of 50 and is commonly installed by millworkers, furniture assemblers, fixture builders, and maintenance technicians who need reliable threaded connections in non-metallic substrates.

This flush hex drive insert is suited for residential and light commercial applications where a clean, surface-flush installation is required. Typical use cases include cabinetry, enclosures, jigs, and fixtures where 1/4-20 machine screws must engage a secure, reusable thread in a softer base material. The flush design sits at or just below the surface after installation, leaving no protruding flange. Each insert in the 50-pack is identical in specification, making the package appropriate for production runs or repetitive service tasks.

Key Features

• 1/4-20 internal thread for compatibility with standard 1/4-20 machine screws and bolts
• Zinc alloy construction provides corrosion resistance and consistent thread engagement
• Flush drive design installs level with or slightly below the host material surface
• M6 hex drive installation using a standard hex key - no specialized press equipment required
• Requires a 23/64-inch (0.3543-inch diameter) drilled hole for proper seating
• Package quantity of 50 supports production assembly and service inventory needs

Compatibility

Designed as an OEM-style threaded insert for use in wood, plastic, and composite materials requiring a permanent 1/4-20 internal thread with a flush-mount finish.

Installation Notes

Installation is typically performed with a hand tool or drill press using an M6 hex driver. The host material must be drilled to the specified hole diameter of 0.3543 inches before insert installation to ensure proper engagement and holding strength. Avoid over-driving the insert, as zinc alloy is subject to shear if excessive torque is applied beyond seating. Always verify hole depth matches or slightly exceeds the insert length of 0.7874 inches to achieve a true flush installation.
