Here is what I have found. All the current triangle weights fit flush or below flush in the current KE4 Tour heads. Even checked them in a previous KE4 Tour model #6 iron and all fit flush or below flush. The current triangle weights are not all perfectly flush in the current KE4 S heads. I found the 2 gram and 4 gram weights were flush to .2 mm raised, which is hardly noticeable. The 12 gram and 14 gram were approximately .4 mm (that’s 4/10 of a mm) above flush. I checked all the new triangle weights on a #6 iron of the older model KE4 Forged head and all the weights were flush to below flush. We did have to change the weights (from the original 3 prong weights) when we had to re-tool the KE4 S iron. Some of the old 3 prong weights would not have fit flush or even close to flush on the new KE4 S iron and the 12 and 14 gram weights might not have been perfectly flush on the KE4 Tour heads. I know not flush is not ideal, but all I have found are pretty close to flush with the current heads and screws. I’ll check some more heads and screws and post if I find anything else. Thanks for letting us know what you are experiencing.
