Hmm that picture of those wheel lugs don't look correct. Check this out. You may need something like this
Usually RacingHarts have a small working area when you torque up those lugs onto your rims. They will probably require those type of lugs. If you do have the bolts already which sounds like you already have the proper ones since you went to the autostore.Discount Tire usually sells these lug key locks ask your local rim shop they should carry them. Here's what you may need
1 wheel lock key tool - above the longer chrome piece is the wheel locking device to the left.
Lug nuts (5 bolt application) That use the same lock key tool so you'll be able to remove and put on your rims.
1 lug nut installation tool
3 To the right are the wheel locks they also require a key locking device if you plan on puting wheel locks to project your investment.
The center with the black rubbers are what's inside your rims if you already have tires on your rims most likely you have those. "those are the valve stems where you put the air"
Anyway most likely it just sounds like you'll just need to get a wheel lock key tool. I use reverse locking lugs they are they same concept except the key has an inverted pattern when bolting the rims down.
Hope this helps ya out a bit! Lemme find a pic of how my rims are installed.
