- What is Phillips Screwdriver?
Phillips-head drivers are used on cross-slotted screw heads with modified U-shaped slots of uniform width. Screws of this type are often found on automobile trim and electric appliances. Sizes range from 0 to 4, with 0 being the smallest.
- What is Torx Screwdriver?
Torx drive system provides six lobular drive surfaces mated from lobes of the driving and driven elements. Drive surfaces have vertical sides that permit the maximum torque application to assure reliable clamping force. All driving torque is transmitted as a perpendicular force to the driven element so there is no cam-out.
- What is Regular tips?
Regular tips are used with large, heavy screws. Tip is flared so it is wider than the driver bar. Quality drivers with regular tips should be accurately ground for uniformity. Blades should not taper too sharply from the tip, because an improperly tapered tip has a tendency to rise out of the screw slot.
