Spring Tools Heavy Duty Stamping System
A great way to mark any of your projects, tools or parts! All you do is firmly hold the tool tip onto wood, mild steel or virtually any surface you are aiming for, pull the other end back and let it snap! This generates up to 5000 pounds of impact striking force with pin point accuracy and is guaranteed to never double stamp! The clever “no-pinch” design on the spring guarantees you never get pinched and the spring itself is good for up to 1 million pulls! System includes square driver and 39 pieces of ¼” stamps (A-Z, 0-9, &, and * for punctuations.) Spring Tools have a lifetime warranty and are proudly made in the U.S.A.!
Rockwell hardness is approximately C 57.
