KATO LockOne

KATO LockOne®

A Superior Locking Force

KATO’s NEW LockOne is a revolutionary positive locking product designed to prevent a standard nut from loosening 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.

LockOne prevents the nut from loosening from the bolt!

LockOne Specs

Effective

LockOne is tested in accordance with NAS3350 (National Aerospace Specification for impact type vibration test). LockOne can be easily substituted into existing designs. LockOne is reusable, does not degrade with each cycle.

Easy Assembly

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 is adjustable and removable after installation with the same 12-point socket.

Made for the Environment

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.

Design and Assembly Information

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. When using any fastener with a degrading locking feature such as a locking compound or nylon built into the nut, replacements are needed during any maintenance as they can only be used once. With LockOne, this positive locking feature can be simply removed and reused. No extra stock needed!
