Benefits
- Connection part from 1/4" square socket to 1/2" external square
- Ball stop groove to safely lock the socket
- Knurling at the rear end for a good grip during manual use
- Chrome-vanadium steel, matte-chromed, for high load capacity
- For manual and machine-operated use (non-impact)
Applications
For workshop, assembly and maintenance work where 1/2" sockets are needed on a 1/4" drive, for example for lightly tightened fasteners with a large across-flats size.
