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.

The knurled body of the rivet nut provides increased resistance to turning in the application – especially when they are installed into softer materials.

Body Types available in Open end style.

Round Body

This type has wide usage as round holes are easy to make.

Semi Hex Body

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.

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.

Full Hex Body

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

The full hex body affords a very good resistance to failure due to torque loads.

Application considerations

Panel material is not limited by hardness or type, but hole location and thickness must fall within the grip range of the
specified fastener.
Hole locations are important when it comes to clearance on both the front side and back side of the panel. Allow
adequate room for the head of the fastener, the bulbed portion of the fastener, as well as access for your chosen
installation tooling. Also allow enough depth behind the panel to accept the fastener prior to the installation process.

Mounting hole considerations

Mounting holes can be prepared in many ways, but must be within the tolerances specified in the catalog or on the
drawing.
Methods of hole preparation include but are not limited to punching, drilling, milling, laser or water jet cutting, and
casting. Also available are portable hex cutter tools, used to transform round holes into
hexagonal holes.
Mounting holes do not necessarily need to be de-burred, but must allow for the fastener to seat properly and
maintain position or perpendicularity when installed.
