Keystone Tip Screwdrivers
Choosing a Keystone Tip Screwdriver
A keystone tip flares wider than the shank before narrowing to the blade edge. That wide blade fills large slotted screws and resists cam-out under heavy torque. Klein makes most of this collection, with round-shank and square-shank BD drivers, 602 heavy-duty round-shank drivers, Journeyman drivers, demolition drivers with strike caps, an 18-inch C718, and the A010 pocket-clip driver. Knipex adds MAXXPRO Plus slotted keystone drivers.
What to Look For
- Tip width. Match the tip to the screw slot. Sizes here run from 3/32 to 1/2 inch.
- Shank shape. A square shank takes a wrench for extra turning force.
- Length. Short drivers fit tight spots. Long drivers reach deep into equipment.
- Strike cap. Klein demolition drivers can be struck with a hammer to free stuck screws.

Keystone Tip Screwdrivers FAQ
Keystone tip or cabinet tip?
A keystone tip is wider than the shank, so it grips large exposed screws well. A cabinet tip is no wider than the shank, so it can reach screws sitting in a recess or counterbore.
Round or square shank?
Round shanks turn smoothly by hand. Square shanks let you put a wrench on the shaft for stubborn screws, as on the Klein BD284, BD306, and C718.
