Weights should be exact and I have not noticed any QC issues over the years which is one reason why I like Titleist and SC so much. Like many others in this community I have a whole drawer of weights depending on what preferences I have for many putters. Good Question!

Chris,

I too have a collection of weights for various putters and conditions.

Just recently I have been checking the actual specs to the number on the weight...to my surprise there are some that are a few grams off. All the weights are original's from my putters. It may be my kitchen scale...I just find it interesting a bit.

Heavy Thoughts,

Wow! that is surprising...I will go through and weigh a few for a test this weekend!  I am shocked though, if true, that QC is that far off.  Whatever scale one uses though needs to be calibrated though in advance.  I have one at a friends industrial plant that I may consider using to ensure accurate readings.  Thanks for bringing this topic up!
