Nap Replacement Blades Thunderhead 100 Gr. 18 Pk.

The NAP Replacement Blades Thunderhead 100 Gr. 18 Pk. is an essential resupply for serious bowhunters who rely on New Archery Products' proven Thunderhead broadhead system. Whether you've damaged blades on impact, dulled edges from field practice, or simply want to maintain multiple broadheads throughout the season, this 18-pack of replacement blades eliminates downtime and keeps your arrows mission-ready. These blades are engineered specifically for the Thunderhead 100-grain platform, ensuring perfect fit, alignment, and aerodynamic performance on every shot.

Thunderhead blades are manufactured from high-carbon stainless steel and designed for consistent, repeatable expansion and penetration. The 100-grain configuration delivers optimal kinetic energy retention at extended distances while maintaining the shallow-angle blade geometry that minimizes deflection through bone and heavy hide. By purchasing replacement blades rather than entire broadhead assemblies, you preserve your proven ferrules and heads while upgrading cutting edges to factory-fresh sharpness. The compact, lightweight package—just 0.05 lbs for all 18 blades—makes it simple to pack multiple sets into your hunting kit without adding bulk.

Bowhunters who shoot high-volume practice sessions, hunt across multiple seasons, or maintain a quiver of backup broadheads will appreciate the cost-effectiveness and convenience of blade replacement. This pack is compatible exclusively with NAP Thunderhead broadheads in the 100-grain weight class—verify your existing broadhead model before purchase. Installing replacement blades takes minutes and requires only a simple blade-swap procedure detailed in NAP literature. Keep one pack in your truck, lodge, or range bag to ensure you're never forced to hunt with dull or damaged cutting edges.
