Stahl centerless ground ejector pins are made from high carbon steel from durability in operation. 

Two semi-finished hex nuts and two semi-finished hex jam nuts are furnished with each pin. 

For applications that require longer lengths or where rigidity is considered important we suggest the use of Stahl standard stock extensions for ejector pins.
