Schröder | Insert Bit Square Recess Classic No 2
A Robertson, also known as a square or Scrulox screwdrive 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.
Universal hexagonal shaft in 6,35mm (¼ inch)
Based on the Standard Bit, the other bits are optimized by means of various hardening and coating methods. It provides a consistent hardness of ~700HV and features a highly accurate fit in the screw.
The Classic Robertson Bit is hardened using a special procedure. The tough version resulting from this method meets the demands across all areas of industry and craft.
- Security applications
- One-handed use
- Accurate fit in screw head
- Specific driver for each diameter fastener
- ¼ inch drive
- Available in different packaging and quantities
