5/16" Keystone-Tip Screwdriver

The Klein Tools 409-600-6 is a 5/16-inch keystone-tip hand screwdriver built for demanding fastening tasks. Its heavy-duty square shank allows wrench-assisted turning when extra torque is required.

Professional Trades and Heavy Fastening

This screwdriver suits electricians and mechanics who regularly drive large slotted screws and need the leverage of a wrench on the shank. It is not intended for Phillips, Torx, or precision screw profiles. Buyers who require insulated handles for live electrical work should select a different tool.

5/16" Keystone Tip and Square Shank

The defining specification is the 5/16-inch keystone tip combined with a heavy-duty square shank. This profile fits wide slotted fasteners and accepts a wrench for high-torque applications. Confirm the fastener slot width matches this tip size before purchase.
