EV Battery Enclosure Fasteners: Rivet Nuts, Bolts and Threaded Inserts

EV Battery Enclosure Fasteners: Rivet Nuts, Bolts and Threaded Inserts

Comparing Fastening Technologies for Battery Pack Manufacturing

EV battery enclosures can use several different fastening technologies.

The right choice depends on panel material, thickness, accessibility, sealing, serviceability, production method, and load requirements.

Rivet Nuts

Rivet nuts create a threaded fastening point in sheet metal.

Advantages include:

• Blind installation

• Thin-panel compatibility

• Reusable threads

• Efficient installation

• Suitable for aluminum structures

Consider sealed rivet nuts when environmental protection is an important design requirement.

Weld Nuts

Weld nuts provide a strong, permanent threaded attachment.

They may be suitable when:

• The component is assembled before enclosure closure

• Welding is available

• Permanent attachment is preferred

However, welding can introduce heat and additional manufacturing steps.

Threaded Inserts

Threaded inserts can be suitable for:

• Plastic components

• Composite structures

• Specialized housings

• Molded parts

The installation method depends on the material.

Bolts and Nuts

Traditional bolts and nuts remain suitable where both sides of the assembly are accessible.

However, they can be difficult to use in closed structures where rear access is limited.

Blind Rivets

Blind rivets are suitable when a permanent non-threaded connection is required.

They are generally not intended for repeated disassembly in the same way as a threaded insert.

Comparison

Selecting the Right Technology

The correct fastener should be selected according to the complete manufacturing and engineering requirements.

For an aluminum EV battery enclosure with limited rear-side access and a requirement for reusable threads, a sealed rivet nut can be a practical solution.
