Those terms are not interchangeable.
Elises and Exiges use lug bolts/wheel bolts as opposed to some cars which have studs and then use lug nuts/wheel nuts.
If you have already removed the locking bolts you can get four new, non-locking, ones from Lotus to remove the lock issue. Alternatively you can replace all 16 bolts with BMW ones which also elminates the need for the Lotus splined socket tool.
As another solution you can get a stud kit which will conver your Elise to studs/nuts (available from sector 111).
PS: all Elise/Exige models have the staggered wheels.
