Circular/Hybrid ESF Bolts
Bolts are a very common fastening element of CESF and hybrid ESF frames. In general, they are available in 2 major sizes or diameters for mini or standard frames. Within each frame size, bolts are available in different lengths and for different functions such as a general fastener, a wire holding bolt, or a pin holding bolt.
Hex Bolts
The most common general purpose bolt and also a component of the SK™ ESF clamp assembly, hex bolts are available in two diameters (mini and standard) and a variety of lengths. They serve a variety of purposes in the construction of hybrid and CESF frames.
Cannulated/Slotted Wire Fixation Bolt
Available for mini and standard hybrid ESF and CESF frame use, these bolts are designed to hold fixation wires and small pins to rings. Both slotted and cannulated to simplify capture of wires where they exit at a ring’s surface.
Half-pin Fixation Bolt
Currently available for standard CESF and hybrid ESF system only. This bolt is designed to anchor traditional half-pins to rings. Accepts 3.0mm to 4.8mm pins. Smaller pins can be used if extra fill provided. (U.S. Patent # 5,921,985)
