Archery enthusiasts, this set of stainless steel inserts and outserts is exactly what you need to upgrade your carbon arrows for better performance and durability! Each insert weighs 68 grains while the outserts come in at 35 grains, giving you precise weight distribution for optimal arrow flight. Made from tough titanium alloy, these components offer incredible strength and rigidity while being about half the weight of regular stainless steel - that means faster arrow speeds and better energy transfer. They're designed to prevent carbon arrows from cracking, which is especially important if you're using them for hunting where reliability is everything. The package includes 12 complete sets neatly organized in an elegant metal box, so you've got plenty for multiple arrows or backups. They fit carbon arrows with an internal diameter of 4.2mm (that's 165) and work with external diameters ranging from .230 to .256 inches, covering most standard arrow sizes. The 8-32 American standard thread means they're compatible with broadheads, stainless steel target points, and bullet points - no special adapters needed. Whether you're tuning your target arrows for competition or setting up hunting arrows for your next trip, these quality inserts and outserts provide that professional-grade connection between your arrow and point that makes a real difference in accuracy and consistency. The precision machining ensures perfect alignment every time you screw in your points.
