RECESS GUIDELINES
Choosing the correct drive
recess for an application can mean the difference
between optimum productivity and down time.
Often these decisions are only addressed when
problems occur in the production line. ZāGO
offers the above information to assist in the proper
selection of driving recess for your seal screw
application. For a difficult assembly
application, we also offer assistance from our
engineering department to help in resolving existing
problems or to improve your product drive system.
HEAD
STYLE
After you have chosen the correct recess system,
you will next have to select the appropriate head
style. ZāGO can
supply all types of head styles including pan heads, flat heads, button heads,
round heads, truss heads, oval or raised heads,
bugle head, cheese head, fillister head, socket head
and mirror head screws.

ZāGO
offers you the choice of military standard screws or
other head style designs. Make sure to take
into account all design factors, such as torque
transfer stress in the fastener recess and the open
diameter to be sealed. In addition, you may
want to consider the availability and cost due to
the fact that there are standard head styles for
certain drive systems and that some head styles do
not accept all recess systems.
MATERIAL
ZāGO’s
fasteners are available in a number of different
materials. The most common material requested by
ZāGO’s customers is stainless steel. Where great resistance
to weather or corrosion is required, stainless
steel, titanium, brass or bronze may be used, or a
coating such as brass, zinc or black oxide applied.

lengths of threads and special threads such as left
