Detailed Description
Overview
Our Slotted Cross Dowel Barrel Nuts (also known as furniture dowel nuts or cylinder nuts) are specialized internal-threaded fasteners designed for right-angle corner joints in wood and composite panels. Featuring a perpendicular tapped hole through the side of the cylinder and a slotted groove on top, these nuts allow users to easily orient the internal thread using a standard flathead screwdriver while threading connector bolts from the side.
Cold-headed and precision-machined from quality carbon steel, these barrel nuts deliver exceptional pull-out strength, preventing joint looseness in knocked-down (KD) furniture assemblies.
Key Features & Advantages
- Precision Perpendicular Tapping: Clean, burr-free threads centered perpendicular to the body ensure effortless bolt engagement.
- Screwdriver Alignment Slot: The top slot allows easy visual and manual alignment of the threaded hole inside pre-drilled timber pockets.
- High Joint Clamping Power: Distributes heavy tensile load across the timber grain, providing rock-solid corner stability for heavy furniture.
- Corrosion Protection: Available in yellow zinc, blue-white zinc, or nickel plating for smooth aesthetics and moisture resistance.
