I guess I would study the seating area of the locking nut and see if it matches that of standard nuts. If not, I definitely would question this.

I hope you resolve this.

Thanks for reply, The seating area looks the same angle, the difference is the washer is about 3mm smaller and threaded stem 3mm shorter from washer to end, not sure looks ok but do know if it would have any effect on retaining wheel, thanks

When I do a google it seems PW456- is definite for a Toyota and Lexus. But then there are too many variants for all the vehicles which I find strange. When I have been asked to design things for many platforms I am asked to make them common across all, seems Toyota did not do this with wheel nuts.

I cannot find any information for PW456-00002 but for PW456-00003 I find these are used for RAV4 2016. - 2012.

I personally would feel uncomfortable putting these on considering safety issues. Fasteners are designed to stretch which puts a pre-load on, and so takes a certain amount of friction and torque to undo them. If you do use them why not put a pen mark on them so you can check periodically if they are moving.

if you can send them back, I would do this myself.
