Genius Tools Star Head Drivers 1/2" Dr.
Large internal star screws on suspensions, brake calipers, seat mounts and machinery often need more force than a small driver can deliver. These Genius Tools star head drivers use a 1/2" drive, so you can fit them on a full-size ratchet or breaker bar.
The series covers twelve sizes: T-10, T-15, T-20, T-25, T-27, T-30, T-40, T-45, T-50, T-55, T-60 and T-70. Each size comes in 60mm and 76mm overall lengths, for twenty-four drivers in total.
The six-lobe star profile spreads turning force evenly, so the tip stays seated and is less likely to strip the recess, even on tight fasteners. The 76mm drivers add reach for recessed screws, while the 60mm versions keep things compact.
All drivers are made of Chrome Molybdenum Steel to handle 1/2" drive loads. Choose single sizes for a specific job, or build a full set to cover star fasteners from light trim to heavy suspension work.
