Engineered for Strong Arrows and Precise Shots
Compatible with standard and micro diameter arrows, Iron Will’s Reinforced HIT System is a composite layering of hardened metal, carbon fiber, and hardened metal to provide improved arrow connection strength over outserts or half-outs. Patent Pending.

If you’ve ever tried Iron Will broadheads, you know they’re the most reliable broadheads available. After eliminating weak broadheads as a potential point of failure for hunters, we went to work engineering a solution to a secondary weak point – the connection between the broadhead and the arrow shaft.
After relentless testing, both in the lab and in the field, we found a composite system of hardened steel, topped by an arrow’s carbon fiber, topped by an additional layer of hardened steel greatly improves arrow connection strength over outserts or half-outs. The resulting Iron Will Reinforced HIT System ensures arrows hold strong on hard-hitting impacts, maintaining their momentum all the way through the animal.
How to Order Your Reinforced HIT System
If you haven’t done it before, you may have some questions about selecting the right components for your Reinforced HIT System arrows.
Let’s walk through it.
Step 1: Select the Iron Will HIT Insert That Fits Your Arrows
1 | Select Your Desired Weight
Choose from the available options of 15, 25, 50 ,75, & 100 grains to achieve your desired front-of-center (FOC).
2 | Identify the Inner Diameter of Your Arrow
Choose the .204" diameter with standard #8-32 threads if you are shooting small diameter arrows like 5mm Axis, 5mm FMJ, Rampage, RIP TKO, or Kinetic arrows, for example.
Choose the .166" diameter with Deep Six #6-40 threads if you are shooting micro diameter arrows like the 4mm Carbon Injections, 4mm FMJ Injections, Deep Impact, X-Impact, VAP TKO, or Kinetic Pierce arrows, for example. Note: to use our Reinforced HIT System with micro diameter arrows, you will need to shoot Deep Six field points and broadheads.
Step 2: Choose Your Impact Collars
1 | Select Your Desired Weight
Choose either the C10 (10 grain, Grade5 titanium, 0.7" long) or the C25 (25 grain, Hardened Steel, 1.0" long) Impact Collar depending on the weight needed to achieve your desired FOC.
2 | Identify the Outside Diameter of Your Arrow
Arrow outside diameters will vary with arrow type and spine. Choose the size (A-H) so that the inside diameter of the Impact Collar is .001 to .006" larger than your arrow outside diameter. This is listed for many arrows in this Compatibility Chart.
Step 3: Order Field Points and Broadheads
1 | Select Your Desired Weight
Choose a weight that complements your HIT Insert and Impact Collar weight to achieve your desired FOC.
2 | Select Standard or Deep Six Threads
Choose Standard Threads for .204 ID arrows and Inserts or Deep Six for micro .166 ID arrows and Inserts.
