- cr-mo alloy steel - cr-mo impact socket features with added hardness, higher working temperatures, and corrosion resistance. Much stronger to stand greater impact force than chrome vanadium ones.
- cold forging & heat treatment - greatly improve their performance with enhanced strength, increased wear-resistance, and lifespan. Black phosphate finish is for corrosion and wear-resistance.
- secure & stable - spring-loaded detent balls firmly latch onto sockets, and the through-hole in the drive ends locks security onto the drive tang.
- wide application - these extension bars can extend the length to access hard-to-reach fasteners, widely used on car, bicycle, or industrial jobs.
