LOCKONE
REVOLUTIONARY LOCKING SYSTEM
NAS3351 COMPLIANT
CONFORME NAS3351
Prevents loosening of standard nuts or bolts caused by strong vibrations. When LockOne is tightened against the nut, it prevents loosening. Installs with standard wrenches.
Easy to remove – Reusable – Corrosion-resistant
Replaces: cotter pins, brake cables, adhesive compounds, double nuts, lock nuts, crown nuts, serrated nuts or washers, and other types of locking fasteners.
Ideal for a wide range of applications in industrial, railway, transportation, construction, aerospace, energy, etc.
EFFECTIVE
The LockOne fastening elements have undergone accelerated vibration testing with 30,000 cycles in accordance with NAS3350 regulations (National Aerospace Specification for impact-type vibration testing). After 180,000 cycles, the assembly to which LockOne was applied remained securely fastened. LockOne can be easily applied to components already in use. It is reusable and does not degrade with each loosening cycle.
DESIGN AND INSTALLATION
Designing for the use of LockOne couldn’t be easier; simply consider an extra length of three threads in the bolt. Its compact nature makes it ideal for projects with weight restrictions and maintenance programs. When using any fastening element with a degradable locking function, such as a compound or a nylon element embedded in the nut, replacement is necessary during maintenance interventions, as these systems are either single-use or have degraded locking features in subsequent uses after the first. With LockOne, the locking function does not degrade and can be removed and reused. LockOne is quick and easy to install—no compound to apply; a standard 12-point hex socket wrench is all that’s needed to simultaneously install LockOne and the nut.
ENVIRONMENTALLY FRIENDLY
LockOne is designed for challenging environments without the use of hazardous chemical coatings. Made from AISI 304 WPB stainless steel, LockOne is naturally corrosion-resistant.
