M6 x 40mm x Ø10mm Cross Dowel / Barrel Nut - Centre Threaded

The M6 x 40mm Cross Dowel Barrel Nut is a robust, dependable fastener designed for high-strength joints in furniture manufacture, engineering builds, and professional assembly work. Also known as a cross dowel or barrel nut, it features a centre-threaded bore for accurate alignment and a slotted head to help you position the fixing quickly during installation.

With a length of 40mm and an Ø10mm body diameter, this M6 cross dowel is widely used across engineering, exhibition stand construction, and furniture production—especially for larger items such as slatted bed bases, beds, cots, cabinets, and similar structural furniture where a secure internal fixing is essential. Manufactured in Europe from 4.8 steel and finished in bright zinc plating, it offers consistent performance and corrosion resistance for long-lasting results.

Ideal for trade customers looking for an importer/wholesaler supply option, these fasteners are available sold individually or in bulk packs to match your workshop and production needs: 100 packs, 500 packs, and 1000 packs (carton quantity). We also stock M6 cross dowels in multiple lengths for different build requirements.
