Screws without special treatment
 S1  Special processing of the screws for viscosities 100 to 250 cSt
 S2  Special processing of the screws for viscosities 250 to 500 cSt
 S3  Special processing of the screws for viscosities 500 to 800 cSt
 S4  Special processing of the screws for viscosities over 800 cSt
S1..S4 = poor efficiency. We recommend the SMT SN series
 HD  phosphated shafts
 HA  case-hardened shafts
