Yankee Screwdriver Hex Bit Adapter

Hex Bit Adapters for Yankee® Screwdrivers

Boost the versatility of your Yankee-style spiral screwdriver with these handy hex bit adapters. Designed to broaden the range of bits your tool can use, these adapters let you take full advantage of the screwdriver’s ratcheting mechanism, extended reach, and precise torque control—while using standard 1/4" hex bits.

Each adapter includes a built-in rare-earth magnet that firmly grips ferrous screws, and it works with both smooth and grooved shank bits.

Available in three sizes to fit most Yankee models:

• 5.5mm (7/32") – Fits models 133, 135, and 233

• 7mm (9/32") – Fits models 30 and 130

• 8mm (5/16") – Fits models 31 and 131

An affordable, no-fuss upgrade that makes an already adaptable tool even more useful.
