A recessed bolt is a bolt whose head is countersunk or partially embedded into the mating material, such as wood, metal, or plastic.
The bolt head fits into a recessed hole (a cavity or counterbore) made to match its shape.
After tightening, the surface remains flat or slightly indented, rather than having the bolt head protrude.
Smooth surface finish — prevents catching, snagging, or interfering with moving parts.
Aesthetic appeal — gives furniture, machinery, and panels a cleaner, more professional look.
Protection — recessed heads are shielded from impacts or wear, reducing the risk of stripping.
Safety — minimizes protruding hardware that could injure workers or damage materials.
Aerodynamics or fluid flow — ideal in automotive, aerospace, or machinery applications where drag or turbulence matters.Common Types of Recessed Bolts
To make the bolt recessed, the material must have a counterbore (flat-bottom hole) or countersink (conical hole).
The recess is made using a drill bit or countersink cutter that matches the bolt head’s shape.
When installed, the bolt sits flush or below the surface, and a matching nut or threaded insert secures it from behind.
Machinery & equipment assemblies – to prevent bolt heads from snagging on moving parts.
Furniture and cabinetry – for smooth, clean surfaces.
Automotive & aerospace – where flush surfaces improve performance or safety.
Metal fabrication & enclosures – to protect bolt heads from corrosion or tampering.
Our recessed bolt is any bolt installed into a hole so its head sits below or level with the surrounding surface — improving safety, durability, and appearance. Contact us!
