What makes Hammerhead Performance Trimmer Heads so tough?
- High-strength cast aluminum alloy protected bump knob ⋅ Critical protection where it counts.
- All nylon parts are not created equal ⋅ Typical OEM trimmer heads contain a nylon reinforced with glass fillers. In contrast, Hammerhead Performance Trimmer Heads use a high-grade, nylon. One strengthened with an elastic formula designed to distribute impact force. As a result, Hammerhead performance trimmer heads can withstand higher levels of impact stress, longer terms of abrasive wear 500 times beyond ISO shock test standards.
- A better fit—right out of the box ⋅ Hammerhead performance trimmer heads set a higher standard. When we make trimmer heads, each part measures within tenths of millimeters from each other — meaning a glove-like fit and no fiddling with stubborn parts. No struggle to put together a trimmer head. With Hammerhead all parts slide together smoothly ever single time.
- A wobble free arbor ⋅ Hammerhead performance trimmer heads bolt to a billet aluminum center arbor contained within a carbon fiber assembly. A better way to attach a trimmer head. While all other trimmer heads provide a universal “bag of bolts” and ask you to pick out one that fits okay. Hammerhead has a large center arbor that is friction fitted and balance checked at the factory for an accurate and smooth spin. One specifically sized to your trimmer’s receiving bolt.
- Superior debris protection ⋅ Trimmer heads fail when dirt and grit get inside. Debris that will quickly wear the moving parts that advance the line. Hammerhead’s large, overlapping interior walls interlock and block foreign matter from entering critical mechanisms.
