Easton's 4mm 8/32 Aluminum Half-Out is machined out of Aerospace 7075-T6 alloy and provides an affordable option for standard thread 8-32 broadheads and field points to be used with most of Easton's 4mm Carbon, 4mm FMJ, and 4mm A/C shafts. Weighing 50 grains and available in 5 sizes to fit a wide range of spines, the half out utilizes a collared design at the connection point of the shaft for increased strength and a precise fit.
