Description
Ball-End Allen Wrenches are essential workshop tools used throughout orthotic and prosthetic fabrication, assembly, and adjustment. Designed for working with inbus (hex) shank screws, these tools provide the precision, reach, and control required for tightening and loosening the fasteners used in joints, adapters, prosthetic components, and orthotic hardware systems.
In O&P workshops—where alignment accuracy and secure hardware fixation are critical—ball-end wrenches offer superior accessibility, allowing technicians to engage screws from angles up to 25° off-axis. This flexibility makes them ideal for confined spaces, multi-component assemblies, and final adjustment tasks on both orthotic braces and prosthetic devices.
Purpose & Function
Ball-end Allen wrenches are used for:
-
Mounting and adjusting prosthetic adapters, pylons, and components
-
Securing orthotic joints, loops, straps, and reinforcements
-
Tightening inset screws inside AFOs, KAFOs, spinal braces, and upper-limb orthoses
-
Quick alignment corrections during fittings
-
Equipment service and workshop maintenance
Their ability to work effectively in limited-access areas makes them indispensable in any professional O&P setting.
