Alcoa Fastening Systems (AFS) has a long history of servicing critical applications on the UK rail permanent way. In many cases, permanence – in the sense of extended fatigue life, security and vibration resistance – has, indeed, been decisive in the selection of Huck® products. One of AFS’ latest developments, though, now presents high levels of surety combined with the flexibility of assembly and disassembly using conventional hand tools.
Safety critical rail applications for which AFS, and in particular its C50L® and BobTail® lockbolts and lockstuds, have provided major advantages over conventional threaded fasteners are to be found in both the switch and crossing zones of the permanent way. The key benefits are immediately recognisable to any engineer familiar with AFS’ Huck® fasteners.(…)
