EV Automotive Blind Rivet Nuts for High-Torque Applications

EV Battery Box Fastening Solution: High-Torque Closed-End Blind Rivet Nuts for Electric Vehicle Assembly

Overview

In electric vehicle (EV) manufacturing, battery pack safety, sealing performance, and structural integrity are critical. Battery enclosures must withstand vibration, thermal cycling, moisture exposure, and mechanical stress throughout the vehicle lifecycle.

EV blind rivet nuts provide a reliable and efficient fastening solution for battery box assemblies, especially in applications requiring high torque resistance, anti-rotation performance, and airtight sealing.

Juxin Fasteners offers advanced battery pack fasteners designed to meet European and North American automotive standards, supporting high-performance EV production.

 Key Features

Closed-End Sealing Design

The closed-end rivet nut structure prevents the ingress of:

• Dust

• Moisture

• Electrolytes

This ensures excellent sealing performance for EV battery enclosures and electrical housings.

 High Torque & Anti-Rotation Performance

Engineered with optimized knurling and deformation zones, these high torque rivet nuts provide:

• Strong resistance to rotation

• Stable thread engagement under vibration

• Reliable fastening in thin sheet materials

Ideal for dynamic automotive environments.

Material & Surface Treatment

• Material: High-strength carbon steel

• Coating: Zinc-nickel plating (Zn-Ni)

• Heat treatment: Improved hardness and fatigue resistance

Benefits include:

• Excellent corrosion resistance (up to 1000+ hours salt spray)

• Long service life in harsh environments

• Compliance with OEM requirements

 Precision Manufacturing

 by using advanced cold heading and extrusion processes, ensuring:

• Consistent dimensions

• Full thread formation

• Reliable deformation during installation

This guarantees stable quality in high-volume production.

 Efficient Installation

·         Suitable for manual, pneumatic, or automated tools

·         One-sided installation capability

·         Ideal for closed or hard-to-access structures

This significantly improves assembly efficiency and reduces labor costs.
