First, these screws are short. Second, these threads are small and tight. A total waste of money. Do not recommend.

Great product, great seller. Works great. Makes it a really clean, custom look. The originals always are worn out from the salt and grime they must endure.

The screws are 1/4 diameter. The instructions are terrible and poorly translated. The caps are cheap plastic that cannot handle a car wash. I wound up buying one-way screws at my local hardware store.
