Screw Grips
The Model 2710-004 side-acting screw grips are some-
what similar to the Wedge Grips, except that the gripping
force is supplied by two tightening knobs on the sides of
the grips (see Figure 1-2). These tightening knobs are
hand-operated, and the jaw faces are self-aligning,
though not self-centering. The clamping force is adjust-
able by how hard the knobs are tightened.
There are several types of interchangeable jaw faces to
accommodate different types of specimens:
•
Smooth Face – This face is used for flat specimens,
such as paper and thin films.
•
Serrated Face – This face is used for flat specimens
of harder material, such as thin sheet metal.
•
Rubber Coated Face – This face is used for flat
specimens that may be slippery, such as plastic films.
•
Line Contact Face – This face has a rubber coated
face on one side, and a horizontal, semi-circular rib
on the other. This face is used for fibers and fine
wire.
