How EVs Are Driving Fastener Demand Growth
As electric vehicles (EVs) continue to replace traditional internal combustion engine (ICE) cars, the demand for electric vehicle fasteners is undergoing a fundamental transformation. In Q1 2026, the penetration rate of new energy vehicles (NEVs) in China reached 52.9%, signaling a major shift in the global automotive industry.
For fastener manufacturers and automotive buyers, this transition is not just about volume changes — it is redefining fastener applications, technical standards, and supply chain strategies.
One of the most significant changes is the restructuring of fastener demand.
A typical ICE vehicle uses around 1,800–2,200 fasteners, with nearly 40% allocated to the engine and transmission system. In contrast, EVs eliminate these components but introduce new applications in:
Battery systems; Electric motors; Electronic control units (ECU); Thermal management systems and High-voltage architectures
As a result, EVs require 20%–30% more fasteners per vehicle, with some high-end models exceeding 4,000 pieces.
More importantly, the value of fasteners per vehicle is increasing rapidly. While traditional vehicles average around RMB 2,000 in fastener value, EVs demand a higher proportion of customized, high-precision fasteners, significantly boosting overall market value.
Key trends include:
1.High-strength fasteners (Grade 10.9 / 12.9 and above)
Widely used in battery packs and structural components to withstand vibration and thermal stress
2.Lightweight materials
Aluminum, titanium, and high-performance stainless steel are increasingly used to reduce vehicle weight and extend driving range
3.Enhanced performance requirements
Corrosion resistance (battery environments), Anti-loosening performance, Electrical insulation, Sealing capability
These requirements make EV fasteners far more complex than standard automotive fasteners.
At the same time, localization is accelerating. Domestic manufacturers are rapidly replacing imports in high-end fastener segments, driven by improved R&D capabilities and the expansion of global EV exports.
What This Means for Fastener Buyers
For automotive OEMs and component buyers, the shift toward EVs requires a new sourcing approach:
Choose high-strength fasteners for critical applications
Ensure materials meet corrosion and thermal resistance standards
Work with suppliers capable of custom fastener development
Prioritize partners with automotive certification and traceability systems
