OPEN End Blind Nuts

The open ended style of this rivet nut allows the stud, or male threaded component, to thread through the rivet nut without limiting the length or protrusion of the male threaded part.

Half-Hex (Semi-Hex) Body Style

The half hexagon body rivet nuts make locating within a pre-drilled hole easier, reducing the time of the installation process.

Sometimes blind inserts turn in the hole when force is used to unscrew the bolt, or turning is caused by high vibrations. The hexagonal shaft prevents this turning, making this type of insert highly used in repair or servicing works.

In critical applications, a hex hole may be desired as insurance against spin out.

They are inserted into hexagon drilled holes which prevent the rivet nut from turning or spinning after installation. This is a more reliable option to prevent rotation than the knurled round body nuts. However these require a hexagonal hole.

The hexagonal shape and large flange gives this type exceptional torque-to-turn strength in thin sheet materials while having safeguards against over-tightening which can lead to thread stripping and the need for expensive rework.

If excessive torque is applied, the screw shank fails before the insert as protection from over-tightening.

Semi-Hex Large Flange [FLAT Head] Blind Nut

The flanged head is used to reinforce the hole and increase resistance to pull-out, making this style of head ideal for load-bearing applications.

These rivet nuts are particularly ideal in applications where high torque-out and push-out performance is required.

The A4 grade stainless steel is the most corrosion resistant grade used for fasteners – holding increased percentages of nickel and molybdenum – meaning a better resistance against aggressive conditions, acids, chlorides and coastal or marine applications.

Semi-Hex Small Countersunk [RCSK] Blind Nut

The reduced countersunk head allows this type of rivet nut to be used in applications without any extra hole preparation, providing a low profile flush fit to the application.

This enables countersunk rivet nuts to be installed in post-painted or pre-coated applications without damaging the surface.
