CrMO is used to construct this socket (Chrome Moly Steel).
Long-lasting durability is a priority in this design.
This is an excellent addition to both the professional and personal toolbox.
Warranty for a Limited Time Onl.
In addition to being made of CrMO (Chrome Moly Steel), the Astro Pneumatic FDM419 1/2 ” Drive Flip Socket 17mm x 19mm is built to last for a long time.
It works fine with size 17, but when I flipped it over to use size 19, the socket became stuck and I couldn’t get it out.
