E-z Lok 240-002-BR 2-56 Unc Brass Threaded Insert Plastic 50pk

Product Description

The E-Z LOK 240-002-BR is a flush press fit threaded insert designed for installation into plastic substrates. Machined from brass, this insert installs without heat or ultrasonic equipment by pressing directly into a pre-drilled hole. It provides a durable, metal-threaded engagement point in applications where the host material cannot reliably hold threads on its own. The 2-56 UNC thread size suits small-fastener assemblies common in electronics enclosures, instrumentation housings, and light-duty plastic fabrications. Overall length is 0.156 inches, insert diameter is 0.135 inches, and the required hole diameter is 0.125 inches. Sold in a package of 50 pieces with no minimum order beyond a single package.

This insert is specified for use in plastic components where a flush-mount, low-profile threaded interface is required. Typical applications include injection-molded enclosures, 3D-printed parts, and thin-wall plastic panels where a protruding insert would interfere with mating surfaces or assembly clearances. The flush design sits level with the surrounding material surface once fully seated, making it well suited for stacked assemblies or panels with close tolerances. Installers in electronics assembly, OEM manufacturing, and custom fabrication regularly specify this insert for small-format 2-56 UNC fastener patterns.

Key Features

• Flush profile sits level with the plastic surface after installation - no protrusion into mating clearances
• Brass construction provides corrosion resistance and reliable thread integrity in plastic hosts
• Press fit installation requires no heat, ultrasonics, or adhesive
• 2-56 UNC thread standard compatible with common small-fastener hardware
• 0.125 inch required hole diameter is achievable with a standard 1/8 inch drill
• Packaged in quantities of 50 pieces, sold individually with no multi-pack minimum

Compatibility

Designed for press fit installation into plastic substrates requiring a 2-56 UNC threaded interface and a pre-drilled hole diameter of 0.125 inches.

Installation Notes

Installation is typically performed by machinists, assemblers, or fabricators using an arbor press or hand press to seat the insert flush with the plastic surface. Drill the host material to 0.125 inches using a standard 1/8 inch drill before pressing. Ensure the insert is driven in straight and fully seated to achieve the flush profile and maximum pull-out resistance. Do not apply excessive force that may crack or deform the surrounding plastic material.
