Half Shaft Nut and Washer – 1020297-00-A and 1020296-00-B

Axle Nut & Washer Kit — Half Shaft / Drive Shaft / CV Axle

Genuine-style replacement Tesla Model S and X half shaft / drive shaft / CV axle nut & washer kit for Tesla Model S and Model X.  This listing includes both the axle nut and the matching axle washer used to secure the half shaft to the hub. Tesla specifies the nut as a torque-to-yield fastener, so using a fresh nut and washer whenever the axle is removed helps maintain clamp load, prevent loosening, and protect the hub and bearing assembly.

Why these need replacement

• Torque-to-yield design — the nut is stretched when torqued to spec; reusing it can reduce clamp load and risk loosening.
• High EV torque — instant torque from the drive unit puts extreme load on the axle/hub interface, demanding a fresh, correctly torqued nut and washer.
• Corrosion and plating wear — road salt, moisture, and repeated service can degrade the zinc-flake coating and washer seating surface.
• Hub and bearing protection — proper clamp load with a flat, undamaged washer helps prevent spline fretting and premature wheel bearing noise or failure.

Our solution

• Correct Tesla spec nut & washer — direct replacements for Tesla P/N 1020297-00-A (nut) and 1020296-00-B (washer).
• M24×1.5 axle nut — matches the OEM half shaft thread and hub design for proper fit and clamp load.
• Matched axle washer — sized for the Tesla M24 axle stack-up to provide a stable, flat clamping surface.
• Grade 8.8 hardware for the required tensile strength in high-torque EV applications, with corrosion-resistant finish.
