M10 x 25mm Metal Type D Nuts | Zinc

The M10 x 25mm Type D Flanged Insert Nut is a heavy-duty self-tapping threaded insert engineered to create a strong, permanent M10 machine thread in timber, MDF, plywood, chipboard and other engineered wood materials. Manufactured from premium zinc alloy die-cast, the extended 25mm body provides increased engagement with the base material, making it ideal for high-load applications where maximum pull-out resistance and long-term durability are required.

The coarse external thread cuts directly into the substrate during installation, producing a secure mechanical fixing without the need for adhesives. An integral flange prevents over-insertion while helping to protect veneered, laminated and finished timber surfaces from splitting or damage.

Designed for demanding furniture, joinery and industrial woodworking applications, these M10 x 25mm Type D insert nuts provide a reliable, reusable threaded fixing that performs exceptionally well under vibration, repeated loading and frequent maintenance.

Why Choose M10 x 25mm Type D Flanged Insert Nuts?

The extended 25mm body provides increased thread engagement compared to shorter inserts, delivering greater pull-out resistance and improved load distribution in thicker timber and engineered wood products. This makes the insert particularly suitable for demanding applications where strength and reliability are critical.

The self-tapping design simplifies installation by cutting its own thread into the material, while the flanged head prevents over-insertion and helps protect finished surfaces. Once installed, the insert provides a durable M10 machine thread capable of withstanding repeated assembly, servicing and vibration without compromising the surrounding material.
