Stahl return pins are fully machined from carbon steel utilizing an improved forged heat. 

Each return pin is furnished with two semi-finished hex nuts and two semi-finished hex jam nuts. 

For most molds mounted in 18 x 24 or smaller machines we recommend 1/2" diameter return pins. For molds being mounted in 30 x 30 and larger machines we recommend 3/4" diameter return pins. 

Please refer to the Typical Permanent Mold Assembly sheet and individual catalogue sheets for all your permanent mold component requirements.
