Power in Partnership: How STANLEY Led an Auto OEM and Tiers to a Successful Battery Pack Assembly Launch

When a leading automotive OEM encountered critical fastening challenges during the launch of its North American EV battery assembly program, they turned to STANLEY® Engineered Fastening. With the shift to aluminum-intensive designs, the need for validated fastening solutions—across both steel and aluminum—was more important than ever. STANLEY stepped in early, offering a comprehensive strategy that included stud welding, self-piercing rivets (SPR), POP® rivet nuts, and threaded screws, ensuring compatibility across mixed-material assemblies.

From prototype to mass production, STANLEY Engineered Fastening provided full-spectrum support: joint validation, hands-on tooling recommendations, and daily engagement with both the OEM and its Tier suppliers. Today, each battery assembly contains over 350 fasteners sourced through this collaboration—with localized supply that meets domestic content requirements across North America, Europe, Mexico, and Asia. STANLEY ability to integrate with the OEM’s engineering, commercial, and supplier networks positioned them as the go-to fastening partner for this and future EV platforms.
