1. A mechanical clamp comprising:
- an elongate band formed with a sequence of slots along its length, said band surrounding a central region of adjustable cross-section area;
an adjustment screw having a head that rotates about a longitudinal axis and having thread portions that extend into respective ones of said slots, said head having an outer surface with a plurality of sides, each side of said plurality having a first edge and a second edge, each first edge and each second edge having a curved portion, said edges extending in a longitudinal direction, said first edge of each side being said second edge of another side, the head having a central point;
a distance from said central point to each side being substantially unvaried along a curved portion of each first edge, said curved portion extending in a positive longitudinal direction and a negative longitudinal direction relative to said central point; and
said clamp being constructed and arranged so that rotation of said adjustment screw controls said adjustable cross-sectional area of said central region,whereby a tool may engage said head and couple torque to said screw about its longitudinal axis when the tool axis is angularly placed from said longitudinal axis.

Abstract
A mechanical clamp used to secure hoses includes an elongated band. The band surrounds a central region and has a sequence of slots along its length. An adjustment screw has a hexagonal head that rotates about a longitudinal axis and has a thread that extends into the slots. Rotation of the screw adjusts the area of the central region. The head of the screw allows a driver to transfer torque to the head of the screw at an angle from the axis of rotation. The head is either curved or angled to allow a driver to efficiently engage the head of the screw during rotation when placed at an angle to the axis of rotation.
