  Go-Thro Definition

  What is a Go-Thro Screwdriver?

  The Hans Go-Thro screwdriver features a full-through shaft that extends from the tip to a hardened steel striking cap at the handle end. Unlike standard screwdrivers, this design allows direct impact with a hammer while maintaining shaft integrity. Combined with a hex bolster (Hex Gear) for extra torque, Go-Thro screwdrivers are built for heavy-duty industrial and workshop applications.
