Blind Rivet Nut Types

Rivets nuts come in two main body types – round or hexagon with either an open or closed-end.

  • Open End – allows an oversized fastener to screw all the way through, proving vibration resistance.
  • Closed End – creates a watertight application using an exact sized screw.

FLAT HEAD KNURLED ROUND OPEN

The most common and widely used rivet nut range. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, DIY and general engineering.

FLAT HEAD KNURLED ROUND CLOSED

Similar to round open rivet nuts, but used when a moisture or pressure-tight seal is required. Used in white goods, electrical enclosures, indoor and outdoor electronic signs, automotive, aerospace, rail and HVAC.

FLAT HEAD PART HEXAGON OPEN

Similar to flat head full hexagon open with a slight reduction in torque loadings. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, as well as the manufacture of heavy goods, bumper systems, seating and vehicle chassis.

FLAT HEAD FULL HEXAGON OPEN

Primarily used where a high resistance thread and anti-rotation is required. Ideal in thin sheet metals. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, as well as the manufacture of heavy goods, bumper systems, seating and vehicle chassis.

COUNTERSUNK KNURLED ROUND CLOSED

Similar to countersunk round open but used when a moisture or pressure-tight seal is required. Used in white goods, electrical enclosures, indoor and outdoor electronic signs, automotive, aerospace, rail and HVAC.

COUNTERSUNK HEAD KNURLED ROUND OPEN

Similar to flat head nuts, but where a flush surface finish is required. Used in a multitude of industries such as aerospace,automotive,rail,HVAC,white goods, electronics, DIY and general engineering.

REDUCED HEAD FULL HEXAGON OPEN

Similar to flat head full hexagon open but where a ‘flush fit’ is required without a countersunk hole. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, as well as the manufacture of heavy goods, bumper systems, seating and vehicle chassis.

REDUCED HEAD KNURLED ROUND OPEN

Similar to countersunk head where a ‘flush fit’ is required without the need for a countersunk hole. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, DIY and general engineering.

REDUCED HEAD PART HEXAGON OPEN

Exactly the same as reduced head full hexagon but with a slight reduction in torque loading. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, as well as the manufacture of heavy goods, bumper systems, seating and vehicle chassis.

Blind Rivet Nut Head Styles

FLAT HEAD

The flat head is the most common and multi-functional head style. It can be used in a conventional way of fixing into one piece of material, or used in multiple materials to clamp them together; similar to a blind rivet connection.

COUNTERSUNK HEAD

The countersunk head is used where a flush or non-interference fit is required. The hole on the installation side of the material needs to ensure the countersink is a little bit deeper than the countersunk head thickness itself. This allows the head of the nut to sit just below the surface of the material after being set by the setting tool, giving a non-interference fit. As with flat head, it can be used in a conventional way of fixing into one piece of material, or used in multiple materials to clamp them together.

REDUCED HEAD

The reduced head is a specialist version of the countersunk head. It can be used where a flush type finish is required where a noninterference fit is not critical. The rivet nut can be set without the need to produce a specialised hole, therefore is a more cost-effective fixing choice. The reduced head is ideal for very thin sheet materials where a countersink hole could not be produced due to insufficient material thickness. Due to the reduced head, and smaller grip range availability, this product is more suited to single thin sheet materials.
