Square Recess | Robertson Bits
Square Recess Bit: No. 2 (length: 25 mm)
Packaging: 2 Pack Carded
A Robertson, also known as a square or Scrulox screw drive is specified as ANSI
Type III Square Centre and has a square-shaped socket in the screw head and a square
protrusion on the tool. Both the tool and the socket have a slight taper.
As patents expired and awareness of their advantages spread, Robertson fasteners
have become popular in woodworking and in general construction. Robertson screw
bits are easy to use one-handed, because the tapered socket tends to retain the
screw, even if it is shaken.
