The PEM® StickScrew®
System for small-screw insertion has been re-engineered with a new lower-cost
StickShooter™ driver, offering the capability to accommodate
interchangeable nose assemblies and allow for quick tooling changeover. The
self-contained system combines the lightweight air-powered driver with "sticks"
of serially connected hex head screws enabling automatic screw installation
without handling loose screws or driving them manually.
The StickScrew System promotes
torque reliability (due to seating torque built into the screw), increased
productivity, and safer screw insertion. The system can be up-and-running with
minimal operator training.
of serially connected hex head screws are supplied in "sticks" with lengths of
12 inch. Screws install by inserting the stick in the driver, advancing the
stick of screws, squeezing the trigger, and placing the tip of the rotating
screw into the hole. The screw is then driven home and twists off cleanly when
precise seating torque is achieved.
The standard, in-stock product line includes thread-cutting
screws from #2-56 to #6-32 and M3 in 400 series stainless steel. Other
available types and sizes include machine screws and thread-forming screws in a
variety of materials, including steel, brass, and aluminum, and in thread sizes
from #0-80 to #8-32 and M1 to M4. Screws can be plated, black oxidized,
hardened, and otherwise customized to meet application requirements.
