J.W. Winco Canada, Inc., a leading supplier
of standard industrial machine components,
announced it now offers series GN 418 Cam Point
Screws and GN 418.1 Cam Point Levers in metric
sizes. These RoHS compliant components are
maintenance-free clamping elements designed for
a wide variety of different uses and applications,
including clamping flat or round workpieces,
centric clamping in bore holes, and multiple
clamping in tight spaces. They are stable,
compact, and easy to use.
The mode of function is identical for both: The
screw head of the cam point screw is fitted with
two cams: a radial clamping cam (with additional
30° chamfer) and an axial draw-down cam. The
self-locking cam ensures that the clamping force
is of the same magnitude in every angular
position. The force components acting at the
clamping point generate friction and a draw-down
effect which presses the workpiece against a
fixed-end stop. The thread and the 30° chamfer (if
fitted) generate an additional draw-down effect.
Cam point screws are fitted with a hexagon
head socket. The steel is case-hardened, zincplated
and blue passivated. Cam point levers
have a handle (with black plastic ball knob)
connected to the cam point screw with a
serration, allowing the suitable clamping position
to be selected and the lever to be adjusted. Both
the screw and the cam are case-hardened and
burnished. Both right-hand and left-hand thread
types are available.

EFC International, a leading provider of
specialty engineered fastener component parts,
now has stock on the latest PT® screw
development, the Delta PT®, which provides the
optimum thread forming in plastic without any
material damage. The Delta PT® screw provides
better clamp loads and increased joint life in a
wide range of plastic materials.
The Delta PT® screw offers improved
vibrational safety, improved dynamic safety by new
shear area, and high clamp load at smaller
contact pressure by increased flank engagement.
EFC offers professional engineering support
and samples. Delta PT® screw configurations are
available in range diameters of 1.8mm to 10mm,
lengths of 3mm – 100mm and any head style.
Recommended drives are TORX Plus® TORX®
ACR® Phillips II® Phillips Square-Driv® Quadrex®
Type 1A, and Type 1.
