E-z Lok 400-008 Brass Knife Insert 8-32 Pack of 25

Product Description

The E-Z LOK 400-008 is a brass knife insert designed to install threaded inserts into soft materials such as wood, particleboard, and soft plastics without requiring heat or ultrasonic equipment. The knife-style serrated exterior cuts into the host material as the insert is driven in, creating a strong mechanical anchor for 8-32 threaded fasteners. At 0.375 inches in length with a 0.35-inch insert diameter and a 0.5-inch minimum grip requirement, this insert suits tight assemblies where a compact, reliable thread is needed. Installation is handled by joiners, cabinetmakers, and general trade technicians working with threaded fastener applications in light-duty assemblies.

This insert is suited for use in wood furniture, cabinet construction, fixture mounting, and similar applications where a permanent internal thread must be created in a non-metallic substrate. The 8-32 thread size makes it compatible with standard machine screws commonly used in light mechanical and electrical enclosure assemblies. A 0.25-inch drill bit is used to prepare the pilot hole, which must have a minimum grip depth to allow the insert to seat fully and hold under load. This package contains 25 inserts, making it practical for production runs or stocking service kits.

Key Features

• Knife-style exterior cuts into soft materials for tool-driven installation without heat
• 8-32 internal thread accepts standard machine screws
• Brass construction resists corrosion and provides good thread durability
• 0.35-inch insert diameter fits a 0.25-inch pilot hole
• 0.375-inch overall length suits shallow or thin-material assemblies
• Minimum grip of 0.5 inches ensures full seating and holding strength

Compatibility

Designed for installation into wood, particleboard, and soft plastic substrates requiring an 8-32 threaded insert with a 0.25-inch pilot hole diameter.

Installation Notes

Installation is typically performed with a drill press or hand drill using a 0.25-inch bit to prepare the pilot hole to the required depth. The insert is driven using an installation tool or hex key turned under controlled hand pressure to avoid splitting the host material. Ensure the host material provides at least 0.5 inches of grip depth before seating the insert. Always confirm the substrate material is within the hardness range appropriate for knife-style inserts before installation.
