The Flat Head Full Hexagon Body Rivet Nut is a high-performance threaded insert designed for one-sided installation into thin sheet metal, tubes, and profiles. Its six-sided (hexagonal) body locks into a hex-shaped hole to deliver maximum spin-out resistance — making it the strongest rivet nut body style available. Ideal for high-torque, high-vibration applications.
Installation Note: Full hexagon body rivet nuts require a hex-shaped hole in the parent material (punched, laser cut, or machined). They are installed using a standard rivet nut setting tool — compatible with manual hand tools for low volume or pneumatic/battery tools for high-volume production.

A full hexagon body rivet nut has a hexagonal shank running its entire length, which locks into a matching hex-shaped punched hole. Unlike knurled round body inserts that rely purely on surface friction, the hex profile mechanically interlocks with the hole wall along its full length — delivering roughly 10 times the spin-out resistance of a standard round body rivet nut. This makes it the strongest rivet nut body style for high-torque or high-vibration joints.
Yes — full hexagon body rivet nuts require a hex-shaped hole in the parent material, produced by punching, laser cutting or machining, unlike round body types that only need a simple drilled hole. This is installed with a standard rivet nut setting tool (manual for low volume, pneumatic or battery-powered for high-volume production) once the hex hole is prepared.
Open end allows the bolt to pass fully through the insert, so screw length can be varied freely. Closed end seals the bottom to block water, dust and gases from entering through the joint — necessary for outdoor, pressure-sensitive or contamination-sensitive assemblies. Choose based on whether sealing the fastening point matters for your application.
Choose full hexagon body whenever the joint sees sustained high torque or heavy vibration — automotive chassis components, heavy trucks and construction equipment, for example — where round body knurling or half hex alone might eventually spin loose. For general fabrication or lighter-duty assembly, round body or half hex body usually gives sufficient anti-rotation performance at lower tooling cost.
