LockOne Bullet Nut

Mechanically Locking Fasteners

The LockOne Bullet Nut is a revolutionary positive locking fastener designed to prevent loosening under vibration. LockOne Bullet Nut coils stretch when tightened, providing superior locking force WITHOUT cotter pins, safety-wire, adhesives, locking washers, crimp nuts and other types of locking fasteners.

Due to the unique LockOne Bullet Nut design, the assembly is FOD-free. Plus, unlike nuts with nylon or locking compounds, the LockOne does not degrade with use. The design eliminates the need for cotter pins, lock wire, jam nuts, and other locking mechanisms or adhesives.

Once installed, the LockOne Bullet Nut engages the bolt along the pitch diameter inducing spring forces both axially and radially. These forces hold LockOne in place, preventing bolts from loosening under vibration.

Plus, Sky Climber Fasteners can adjust the specifications to meet your requirements in material, finish, and size.  Check out the tabs below for specifications and performance or contact us today to find the right LockOne Bullet Nut for your application.
