Questions about this product
- What are these cross dowel barrel nuts used for?
- They make strong, hidden right-angle joints in furniture. You drop the nut into a drilled cross hole, then run a bolt through to clamp the parts. People use them for bed frames, cribs, chairs, and flat-pack builds.
- Which bolt sizes work with these barrel nuts?
- They take standard M4, M5, M6, and M8 bolts. Lengths grow with size, from 20mm on the M4 up to 30mm on the M8. The M6 nut measures 10mm across, so size your cross hole to match.
- How do I install these cross dowels?
- Drill a horizontal hole, then tap the barrel nut in flush with a hammer. The single slot lets you turn it with a screwdriver to line up the threads with your bolt. Once seated, the joint pulls tight and stays hidden.
