T-Handle Isoryl Screwdriver - for Slotted Heads (AGT.8x100) - 8mm blade. For tightening and loosening the 1/4-20 tripod mount screws on cameras and video recorders. Better torque and greater reach than other T-handle screwdrivers I've seen advertised for this task. Forged blade with chrome finish. (Note - Facom discontinued this item in 2021....I have 1 left in stock. The 10mm size is sold out.)
