Extend or Shrink Your Screwdriver With Drive-Loc System

Drive-loc Overview

The Wiha Drive-loc systems offers you the flexibility of changing the length of your driver blade and type of bit, while keeping the same handle in your grasp. The hex blades are lined with spherical dimples where the handle ‘locks’ into at your specified length. The double ended blades are adjustable to form a 1.7″ blade to a 4.8″ blade in 1/8″ increments.
