Electric vehicle fastening solutions 14 April 2022

A lot of time has passed since the introduction of Electric Vehicles and the transition from Internal Combustion Engine Powered autos and lights trucks will not only continue but accelerate in time. To answer this trend, many REMINC licensees are producing quantities of TAPTITE PRO® and POWERLOK® II fasteners for a variety of EV applications.

Applications for REMINC’s range of thread forming and threadlocking fasteners include EV typical components such as the motor, gearbox, cooling system, inverter, battery box assembly, chassis, suspension as well as brakes and interior corporate fasteners in their design.           

In both steel and aluminium alloy, REMINC says its TAPTITE PRO® screws provide good vibrational resistance and its POWERLOK® II bolts have excellent grounding qualities, as well as both fasteners reducing assembly weight.

REMINC explains: “TAPTITE PRO fasteners are an advance in thread forming technology. Their innovative Parabolic Profile thread form and distinctive cross section provide good axial alignment, low thread forming torque, plus resistance to vibrational loosening and axial pull out. Their hand to glove fit offers excellent electrical grounding qualities, especially important in EVs.”

“TAPTITE PRO’s unique thread design features a predictable failure mode, fastener fracture within the screw threads, eliminating costly nut member repairs or replacement. This is particularly important as many leading OEMs are using more cast aluminium, where stripping a hole in a casting can have significant cost implications. When thread forming screws are not an option, and reliable and secure locking are requirements, POWERLOK II fasteners with their Dual-Angle thread form are the ideal fastener choice.”

The unique thread form of the POWERLOK II provides exceptional vibrational loosening resistance through the creation of physical interference in the root of the threaded nut. This interference eliminates the need for expensive physical and chemical locking solutions, such as patches and adhesives.

Stricter governmental C02 emission limits, increased fuel efficiency requirements, inviting tax incentives, combined with many new EV offerings are paving the road for an EV future. Even though the vast majority of new vehicles sold are still ICE powered, EV adoption is growing. In 2021 BEV (battery powered) and PHEV (plug-in battery powered) passenger car sales grew to almost 4% of total light vehicle sales in the US, 14% in China and 17% in Europe.

Some current forecasts suggest that by 2025, global EV sales will be in the 20% to 25% range, up from 7% in 2021. Many potential EV buyers harbour hesitancy because of high EV pricing, a limited number of convenient charging stations, charger availability, lengthy charging times and driving ranges below 300 miles. However, REMINC believes that these drawbacks will be minimised as EV technology progresses and the charging infrastructure expands.
