The A-50 requires the use of fasteners with an internal, easy leading, 
drive style. Typically utilized drive styles are Phillips, Torx, and Allen. 
Slotted drive and socket-style drives (such as hex bolt style) are not able 
to be used in the A-50 system. 
Bits should be of a type that has a reduced shank at the tip. This is to 
accommodate the space in the bit guide located in the front of the unit. 
The spacing in the bit guide is designed to assist the operator in location 
of the fastener to be picked up.
