RUKO Threaded Insert M3, Drill Hole 6.4 mm, Zinc-Plated Steel

This RUKO threaded insert is a practical solution for creating strong, reusable threads in wood-based materials. Unlike standard screws that can strip over time, this insert provides a durable metal thread that withstands repeated assembly and disassembly.

Highlights

• Internal thread M3 for machine screws
• Requires a 6.4 mm drill hole
• Zinc-plated steel for corrosion resistance
• Flanged head prevents pull-through
• Coarse external thread for secure grip in wood

In daily use

Ideal for furniture construction and interior fittings, this insert is screwed into pre-drilled holes in wood, chipboard, or MDF. The slotted drive allows easy installation with a standard screwdriver. Once seated, it provides a reliable machine thread for bolts or screws, making it perfect for knock-down furniture, cabinetry, and fixtures that need to be assembled and disassembled multiple times.
