KATO LockOne

KATO LockOne®

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 prevents any nut from loosening free!

LockOne Specs

Effective

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 reusable1, does not degrade with each cycle. Made from 304 Stainless Steel WPB, LockOne is naturally corrosion resistant.

Design and Assembly

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 Performance

KATO 3D-LockOne

LockOne surpasses the testing requirements of NAS3350 (National Aerospace Specification for impact type vibration test).


Bolt Pitch

Superior Force

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.


KATO LockOne "How To" Guide


Installation is Easy!

KATO LockOne
