Adjustable Clamping Lever Quick-Hex Socket Female Tapped or Press

Adjustable Clamping Lever Quick-Hex Socket Female Tapped or Press-Fit.

Adjustable clamping levers with 5mm or M4 to 10mm or M16 female press fit holes or threads. These 'Quick-Hex' style clamping levers are particularly suitable when the lever turning angle is limited owing to lack of space. The adjustable handles can be quickly screwed during assembly by means of electric or pneumatic screwdrivers with controlled tightening torque system. For clamping, lift the lever to disengage the clamping device teeth and bring it back to start position. By releasing the lever, the return spring automatically engages the teeth. If the lever cannot make a 360° rotation, the clamping element can be easily screwed by means of the hexagon socket front head screw (after having disengaged the lever).

Why choose ACLHSF adjustable clamping levers for your application?

Adjustable handles are generally used for repetitive clamping operations sometimes with very high-frequency. Therefore, the stress resistance (i.e. the resistance to repeated tightening cycles) of the handle unit is particularly important and, especially, the strength of the toothed element which transmits the tightening force from the handle to the threaded element (boss or stud). In fact, the results of several laboratory tests, performed with a special instrument that simulates the most severe use conditions, have shown that e.g. the adjustable handle can withstand without yielding more than 100,000 tightening cycles, under the action of a force of 490 N
