The titanium alloy SNAP-OFF screws are dedicated for the fixation of the HALLU-C and HALLU-S plates. They are available in different diameters and sizes. They exist in different colors for size identification. The unthreaded part provides the system with the mechanism for the bone to slide along this unthreaded body. The design of the thread allows the snap-off screw to be self tapping so that no pre-tap is required when implanting the device .The distal end of the snap-off screw has a smooth tip to protect tissues.
A small, sterile, threaded rod with a slotted head typically used for internal orthopaedic fracture fixation by being screwed into bone to hold plates or nails to bone or to provide direct interfragmentary stabilization of bone, or it may fasten soft tissue to bone; it is made of a material that cannot be chemically degraded or absorbed via natural body processes (includes implant grade metal such as surgical steel, titanium alloy, or carbon fibre). There are a number of kinds available: cortical, cancellous, malleolar, scaphoid, partially-threaded and fully-threaded, self-tapping, and cannulated. A "lag screw" can be any of these used to obtain compression across bone fragments.
