A Superior Locking Force
LockOne is a revolutionary positive locking fastener designed to prevent a standard nut from loosening free under vibration. Upon installation, LockOne coils stretch, providing a superior locking force. Unlike nuts with nylon or locking compounds, 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! LockOne's lightweight design is perfect for use on weight sensitive applications. KATO LockOne replaces nylon nuts, double nuts (jam nuts), cotter pins, safety-wire, and thread locking compounds.
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. Made from 304 Stainless Steel WPB, LockOne is naturally corrosion resistant.
Designing in LockOne couldn’t be easier! All that's required are three bolt threads beyond the nut. That’s it! It’s compact nature allows for ease of use in designs with weight restrictions and maintenance schedules.
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 can be easily removed and is completely resuable after installation with the same 12-point socket.
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.
Simply load LockOne into the 12-Point socket.
Load the standard nut on top of LockOne.
Tighten to application requirements.
If there is a gap between LockOne and the nut, simply hand tighten LockOne until it is flush with the nut.
