Flat Head Barrel Nuts
Flat Head Barrel Nuts are internally threaded fasteners designed to create a strong, secure fixing point while maintaining a low-profile finish on the visible surface. Featuring a cylindrical body and wide flat head, they are inserted into a pre-drilled hole and used with a compatible machine screw or bolt to clamp two components together.
These barrel nuts are commonly used in furniture manufacturing, cabinetry, display systems, frames, panels and general engineering assemblies where a removable threaded connection is required. The flat head helps spread the load across the surrounding material and provides a neat finished appearance once installed.
Our Flat Head Barrel Nuts are available in a range of metric thread sizes, lengths and body diameters to suit different installation requirements. Options are available in A1 Stainless Steel for general-purpose use and A4 Stainless Steel where improved corrosion resistance is required, particularly in outdoor, marine or moisture-prone environments.
An internal hex drive helps hold and position the barrel nut during assembly, making installation easier while allowing the fixing to be removed or adjusted when required. This makes Flat Head Barrel Nuts a practical choice for applications that require a reliable but serviceable connection.
Typical applications include:
-
Furniture and cabinet assembly
-
Panel and frame construction
-
Display and exhibition systems
-
Machinery and equipment assemblies
-
Joinery and woodworking
-
Commercial and industrial fabrication
