E-z Lok 951618-13 Flanged Hex Drive Insert 5/16-18

Product Description

The E-Z LOK 951618-13 is a flanged hex drive threaded insert designed to install a durable 5/16-18 UNC thread into materials such as wood, plastics, and soft composites. The flanged head seats flush against the surface to resist pull-through, while the hex drive socket accepts a standard hex key for precise, torque-controlled installation. At 0.512 inches overall length with a minimum grip of 0.5 inches, this insert is suited for thinner stock where a full-depth thread engagement is still required. Constructed from zinc alloy, it offers reliable corrosion resistance in light-duty interior applications. Installation requires a 7/16-inch drill and a 0.4331-inch diameter finished hole.

This insert is used in residential, commercial, and light industrial assembly applications where a machine-thread anchor point is needed in non-metallic substrates. Typical scenarios include furniture manufacturing, cabinetry, equipment enclosures, and jig-and-fixture work. The flanged hex drive design is particularly useful when back-side access is not available, since the insert is driven entirely from the front face. Installers in millwork, HVAC panel fabrication, and electrical enclosure assembly commonly use this style of insert when field repairs or component replacements require a reliable threaded connection in pre-drilled stock.

Key Features

• 5/16-18 UNC internal thread for standard machine screw fasteners
• Flanged head design resists pull-through on the installation surface
• Hex drive socket accepts M8 hex key for controlled front-side installation
• Zinc alloy construction provides light-duty corrosion resistance
• 0.512-inch overall length suits thin-material applications with 0.5-inch minimum grip
• Requires 7/16-inch drill bit and 0.4331-inch finished hole diameter

Compatibility

Designed as a standard flanged hex drive insert for use in wood, plastics, and soft composite substrates requiring a 5/16-18 UNC threaded connection.

Installation Notes

Installation is typically performed by assembly technicians, millworkers, or maintenance personnel using a hex key or hex bit driver. Drill the pilot hole to 0.4331 inches in diameter before inserting. Drive the insert squarely into the hole using an M8 hex key to avoid cross-threading or surface damage. Do not exceed the minimum grip depth of 0.5 inches when sizing stock thickness for this insert.
