New BESSEY self-adjusting toggle clamps With the new self-adjusting toggle clamps from BESSEY, work pieces of differing thicknesses can be quickly and securely clamped for machining. This is thanks to uniquely self-adjusting jaw height feature of the BESSEY toggle clamp. This feature makes them ideally suited for small-scale production of a variety of products.

Self-adjusting toggle clamps STC
Even more flexible clamping up to 5-times faster
Uncompromisingly versatile
One size of the BESSEY toggle clamp replaces
multiple competitor sizes simultaneously.
Q due to an extremely large clamping range,
thanks to the patented mechanism
Even sensitive workpieces, e.g. with
veneered or varnished surfaces, can be
gently clamped.
Q due to moving pressure plate with
removable protective cap
Q due to clamping force regulation via
adjustment screw in the joint
Powerful and gentle
BESSEY STC toggle clamps adapt to
workpieces of varying thickness – without
manual setting of the spindle and, with
practically the same clamping force.
Q due to an automatic
clamping width range
