A Superior Locking Force
KATO’s LockOne is a revolutionary positive locking product designed to prevent a standard nut from loosening free under vibration. Upon tightening, the LockOne coils stretch, providing superior locking force. Unlike nuts with nylon or locking compounds, the KATO LockOne does not degrade with each use. Due to the unique LockOne design, the assembly is FOD free. Save on assembly cost! No expensive replacement nuts! The LockOne lightweight design is perfect for use on weight sensitive applications. KATO LockOne replaces double nut (jam nuts), cotter pins & safety-wire.
LockOne fasteners underwent 30,000 cycle accelerated vibration testing in accordance with NAS3350 (National Aerospace Specification for impact type vibration test). In fact, even after 180,000 cycles the LockOne assembly remained intact! LockOne can be easily substituted into existing designs. LockOne is reusable, does not degrade with each cycle.
Designing in LockOne couldn’t be easier! Simply account for an extra three threads to the bolt length. That’s it! It’s compact nature allows for ease of use in designs with weight restrictions and maintenance schedules.
KATO’s LockOne is fast and easy to install. No locking compounds to apply. A standard dodecagonal (12-Point) socket installs the LockOne at the same time as the nut, minimizing installation time. LockOne may also be installed on exisiting applications, simply thread LockOne on the preinstalled nut. LockOne is adjustable and removable after installation with the same 12-point socket.
KATO’s LockOne is designed for harsh environments, without using any hazardous chemical coatings. Made from 304 Stainless Steel WPB, the LockOne is naturally corrosion resistant.
LockOne surpasses the testing requirements of NAS3350 (National Aerospace Specification for impact type vibration test).
Once positioned in front of nut, LockOne engages the bolt along pitch diameter inducing spring forces axially and radially. These forces hold LockOne in place, preventing bolts and nuts from loosening free under vibration.
