  • Drill bits in popular sizes to drill pilot holes or drive screws. The hex shanks fit any standard drill.
  • Sockets (1/4" or 3/8" drive) to loosen and tighten bolts, nuts, and other hardware. Metric and standard sizes are included.
  • Socket adapters to use 3/8" drive sockets on 1/4" drive tools.
  • Nut driver sockets to drive hex nuts and bolts in wood, metal, and machinery.
  • Bit holders to connect screwdriver bits to and use like manual screwdrivers.

Affordable and compact, PTA sets have professional-grade bits and sockets to tackle minor repairs and projects around the house and garage. The variety covers the most common home improvement tasks.
