Thread in Weight Adaptors look under "Arrow Head Adaptors"
Bump up your arrow weight for target shooting or bowhunting with these thread-in weight adapters.
Simply screw these weights into your carbon or aluminum arrow shaft. The adapter will stick out from the shaft approximately 1/2". Your field point, small game point, or broadhead simply screws right into the adapter.
The 25 grain aluminum is great for target shooting, but not recommended for hunting arrows where hard impacts may bend the adapters. The steel 50 and 75 grain models will handle all types of shooting from competitive target archery to big game bowhunting.
Features an outside diameter of 5/16". The industry standard 8-32 thread works with all of today's arrow tips.
