Sealed Rivet Nuts for EV Battery Pack Trays

Reliable Threaded Fastening and Sealing Solutions for Aluminum Battery Enclosures

Electric vehicle battery packs require fastening systems that combine mechanical reliability, serviceability, corrosion resistance, and environmental protection.

As battery enclosures increasingly use lightweight aluminum sheet, extrusions, and formed components, creating durable threaded fastening points in thin-wall structures can present an engineering challenge.

Sealed rivet nuts provide a practical blind-installation solution for these applications.

 They create a mechanically retained internal thread in thin materials while closed-end configurations can help address sealing requirements at the fastening point.

Juxin Fasteners supplies sealed rivet nuts for EV battery pack trays, aluminum battery enclosures, battery housings, and automotive applications,

 with material, dimensional, coating, grip-range, and sealing options available for application-specific requirements.

What Is a Sealed Rivet Nut?

A sealed rivet nut is a blind threaded insert designed to create an internal thread in sheet metal without requiring access to the rear side of the panel.

Unlike an open-end rivet nut, a closed-end sealed rivet nut incorporates a closed blind end. 

This construction can help reduce direct passage through the fastener body and can be integrated with other sealing elements as part of an enclosure fastening system.

This makes the design particularly useful for enclosed structures where the rear side of the panel is inaccessible.

Why Use Sealed Rivet Nuts in EV Battery Trays?

EV battery enclosures can be exposed to:

• Vibration

• Temperature cycling

• Moisture

• Road splash

• Dust

• Cleaning fluids

• Repeated service operations

A sealed rivet nut can provide several practical benefits.

Blind-Side Installation

The fastener can be installed from one accessible side of the panel, making it suitable for closed battery trays and box structures.

Durable Internal Thread

The rivet nut creates a dedicated threaded connection in thin aluminum sheet without requiring a thick threaded boss.

Support for Enclosure Sealing

Closed-end configurations can help reduce potential ingress paths through the fastener itself.

When combined with suitable gaskets, sealing washers, O-rings, or other sealing interfaces, the fastening point can become part of the overall enclosure sealing strategy.

Serviceability

Battery systems may require inspection, maintenance, component replacement, or access to internal modules. 

A threaded insert provides a reusable fastening point for repeated assembly and disassembly.

Sealed Rivet Nuts for Aluminum Battery Trays

Aluminum is widely used in EV battery structures because of its favorable strength-to-weight ratio and corrosion resistance.

However, thin aluminum sheet may not provide enough material thickness for a durable directly tapped thread.

A rivet nut provides a mechanically retained threaded connection without requiring access behind the panel.

Important design factors include:

• Panel thickness

• Grip range

• Thread size

• Pull-out resistance

• Spin-out resistance

• Installation torque

• Corrosion resistance

• Sealing configuration

Sealing and IP Protection

A sealed rivet nut should not be considered independently responsible for an enclosure rating such as IP65, IP66, or IP67.

Final protection depends on the complete assembly, including:

• Enclosure construction

• Gasket design

• Fastener spacing

• Clamp load

• Sealing interface

• Rivet nut geometry

• Installation consistency

• Temperature cycling

• Environmental testing

The rivet nut is therefore one component of the complete battery enclosure sealing system.

Applications

Sealed rivet nuts can be used in:

• EV battery packs

• Battery trays

• Battery module housings

• High-voltage battery enclosures

• Battery pack covers

• Automotive electronics

• Power electronics

• Energy storage systems

• Aluminum equipment enclosures
