Cross Dowel Furniture Nuts are used primarily for receiving a mating bolt through a perpendicular barrel hole in a furniture panel. This page lists the industries and assemblies where they are specified, the selection criteria that matter for each application, installation practice, and the cases where a different fastener type is the correct choice. Parts are supplied to Trade series (cross dowel nuts). Stocked across roughly M4 to M10, they cover general to heavy-duty work.
Typical Applications for Cross Dowel Furniture Nuts
The most common settings where these are specified:
- Flat-pack furniture: Cross dowel nuts clamp panels where the bolt enters perpendicular to the barrel.
- Cabinet production: Galvanized and stainless barrels provide a hidden threaded joint.
- Timber fixtures: The cross bore aligns a bolt through a blind or edge hole.
- Repair carpentry: Metric sizes replace damaged knock-down connectors.
How to Specify Cross Dowel Furniture Nuts for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M4–M10; check the full table below for the exact dimensions of each size.
- Locking & grade: Match the strength grade to the bolt, and choose a locking style (nyloc, all-metal, serrated flange) if the joint sees vibration.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to Trade series (cross dowel nuts). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Installation & Assembly Practice
- Run the nut down by hand before applying the wrench to catch cross-threading early.
- Tighten the nut rather than the bolt head where access allows — the torque-to-preload relation is more consistent.
- For locking styles, note that nyloc inserts are single-use in critical joints and lose grip above roughly 120 °C.
Common Selection Mistakes with Cross Dowel Furniture Nuts
- Pairing a high-class bolt with a lower-class nut — the nut strips before the bolt reaches proof load; the nut class must meet or exceed the bolt class.
- Using a plain nut with a spring washer in severe vibration instead of a prevailing-torque locking nut.
- Re-using nyloc nuts in critical joints.
Where Cross Dowel Furniture Nuts Are Not the Right Choice
Not on their own — they need a matching bolt or stud — and a plain nut is not a substitute for a locking type under heavy vibration.
