EN8 vs EN8D: EN8D is the free-cutting (leaded) variant — same mechanical properties but significantly better machinability on automatic lathes. Both grades stocked.
Typical Applications
Shafts & Spindles — General engineering shafts where moderate strength is sufficient
Studs & Bolts — Fastener stock for medium-strength bolting applications
Keys & Keyways — Standard key stock for shaft-hub connections
Turned Components — High-volume turned parts on automatic lathes (EN8D)
