Robertson #3 insert bit

The Tuff Stuff RS3100 is a single-ended Robertson #3 insert bit with a 1/4" shank and 1" overall length. It fits any drill or driver that accepts a standard 1/4" hex shank. The bit is designed for general-purpose fastening tasks in home, shop or garage settings. Condition is new.

Users needing Robertson #3 drive

This bit suits anyone driving Robertson #3 screws with a 1/4" shank chuck. It is not for users who require a different drive profile such as Phillips, Torx or square sizes other than #3. Builders needing a double-ended bit or a longer reach should look at other options.

1/4" shank compatibility

The decisive specification is the 1/4" hex shank, which determines whether the bit fits your drill or driver. Verify that your tool accepts this shank size before purchase.
