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.
Complete 9-Piece Set – All Essential Sizes
Each set includes the most commonly required hex key dimensions for orthotic and prosthetic work:
1.5 mm
2 mm
2.5 mm
3 mm
4 mm
5 mm
6 mm
8 mm
10 mm
This range covers everything from delicate screws in upper-limb orthoses to large bolts in prosthetic pylons and heavy-duty joints.
