HFH (steel, zinc-plated)
HFHS (stainless steel)
Self-clinching threaded studs for extremely
high torque-out and pullthrough resistance.
33, 67
33, 67
HFHD (steel, zinc-plated)
HFHDS (stainless steel)

HFH and HFHS with a dog point lead-in
option for automatic assembly. Applications
e.g. in automobiles.
34, 68 HFE (steel, zinc-plated) Design similar to HFH and HFHS types
with enlarged head diameter for higher
pull-through resistance.
35, 68 HFED (steel, zinc-plated) Design similar to HFHD and HFHDS types
with enlarged head diameter for higher
pull-through resistance.
Coarse-thread self-clinching studs
36 Coarse-thread
(steel, zinc-plated)
Flush head studs for thru-holes. Assembly
of mating nut via press-on nuts or clips.
