Weds are one of the harder brands to source hardware for. Most of the Kranze line uses a female triple square M7 bolt but that is rather unusual for most brands to carry. Weds does stock some of their wheel hardware, valve stems, and center caps at the following link:

In order to purchase the hardware, you have to go to the Japanese site and sift through the models until you find one with the same kind. The link below has the triple squares at the bottom:

This obviously isnt ideal but it looks like they took the triple square option off the new North American site. You may have to shoot them an email or go through an importer to get those. Sand blasting and chroming (or whatever) will be cheaper and easier imo.
Just for a future reference, Works is much easier to source parts for. Center caps, valve stems, and hardware for every wheel they offer is available at:

Many other companies offer replacements hardware in different coatings or styles but not identical to the Weds, the most prominent that I know being these:
