Custom Cross Dowel Nut And Bolt Sleeve M6 Steel Zinc Plated

Descrizione

A Cross Dowel Nut (also known as a Barrel Nut or Connector Nut ) is a cylindrical fastener with a threaded hole perpendicular to its length. It is commonly used in furniture assembly, cabinetry, and structural frameworks to create strong, hidden joints. The nut is inserted into a pre-drilled hole, and a bolt or screw is driven through an adjoining piece, engaging the internal threads to form a secure connection.

Materials

Carbon Steel – Standard strength, cost-effective, suitable for general applications.
Stainless Steel – Corrosion-resistant, ideal for outdoor or high-moisture environments.
Brass – Non-magnetic, corrosion-resistant, used in decorative or electrical applications.
Zinc Alloy – Lightweight, often used in low-stress applications.

Surface Treatments

Zinc Plating – Provides rust resistance and a shiny finish.
Black Oxide – Improves corrosion resistance and reduces glare.
Nickel Plating – Enhances durability and aesthetic appeal.
Passivation (for Stainless Steel) – Removes free iron and improves corrosion resistance.

Applications

Furniture Assembly (e.g., beds, tables, cabinets)
DIY Woodworking Projects (e.g., bookshelves, frames)
Industrial Equipment (e.g., machinery frames, enclosures)
Modular Construction Systems (e.g., exhibition stands, partitions)

Successful Case: Strengthening a Wooden Bed Frame

Problem Statement

A furniture manufacturer received complaints about weak joints in their wooden bed frames, leading to wobbling and eventual breakage. Traditional screws and bolts were insufficient for long-term durability.

Solution: Using Cross Dowel Nuts

Design Improvement
Replaced standard screws with M8 Cross Dowel Nuts (Stainless Steel, Zinc-Plated) .
Precisely drilled holes in the bed rails and side panels for snug nut insertion.

Assembly Process
Inserted the Cross Dowel Nuts into the rails.
Aligned the side panels and tightened high-tensile steel bolts through the nuts.
Applied thread-locking adhesive to prevent loosening over time.

Results

Increased Joint Strength – The bed frame could now withstand 200+ kg without wobbling.
Longer Lifespan – No loosening or corrosion due to stainless steel and zinc plating.
Aesthetic Appeal – Hidden fasteners improved the bed’s clean, modern look.

Conclusion

By switching to Cross Dowel Nuts , the manufacturer enhanced durability, reduced warranty claims, and improved customer satisfaction. This solution is now standard in their premium bed frame designs.
