General Information
HOLDING CAPACITY
The holding capacity listed for each
clamp refers to the maximum external force that the clamp can safely
resist in its locked position without
incurring any permanent deformation. For hold down clamps, holding
capacity is measured with the spindle
as close as possible to the handle, and
will be less at the end of the clamping arm.

CLAMPING FORCE
Clamping force, the amount of force
actually applied to the workpiece
by closing and locking the clamp, is
generally less than the stated holding
capacity. This allows the clamp to
have ample capacity to resist external machining forces. Actual clamping force depends on many factors
including: spindle position, proper
spindle height adjustment, type of
spindle used, workpiece material, and
the clamp’s mechanical advantage. In
most cases roughly 1/2 of the stated
holding capacity can be applied by
hand with medium effort.
