For what arrows are you asking? If carbon then the typical insert weighs about 15 grains. Nock is about 12 grains. As for vanes it can vary a lot. Typical 4" vanes can weigh from just about 8 grains each to over 12 grains (I've weighed them). Then there are low profile vanes like the Duravane LP 400 that weigh 6.5 grains each. Blazer being popular these days weigh in at 5.5 grains. Then there are feathers that weigh about 3 grains for a 4"er. The new Rayzrs weigh 2 grains each.

If you want to talk about the inserts for Fat shafts or aluminum then these can weigh as much as 35 grains or more.

The values of nocks and inserts will vary a little from each manufacturer, but these are close.
