M5 x 13mm Metal Type D Nuts | Zinc

The M5 x 13mm Type D Flanged Insert Nut is a high-performance self-tapping threaded insert designed to create strong, permanent metric threads in timber, MDF, plywood, particleboard, chipboard and other engineered wood materials. Manufactured from durable zinc alloy die-cast, these threaded inserts provide excellent pull-out resistance while delivering a reliable metal thread for repeated assembly and disassembly.

The aggressive external self-tapping thread cuts directly into the material during installation, eliminating the need for adhesives or specialist fixing methods. The integral flange prevents over-insertion and helps protect decorative or laminated surfaces from splitting or damage during installation.

Ideal for both production environments and repair work, Type D insert nuts are widely used across furniture manufacturing, cabinetry, shop fitting and commercial joinery.

Why Choose Type D Flanged Insert Nuts?

Unlike conventional wood screws, Type D threaded inserts create a permanent metal thread that can withstand frequent removal and refitting of machine screws without degrading the surrounding material.

The external self-tapping thread provides exceptional holding power, while the flange distributes installation forces across the surface, reducing the likelihood of material damage. This makes Type D insert nuts particularly suitable for applications subject to vibration, repeated maintenance or regular disassembly.
