SELF LOCKING, VIBRATION RESISTANT
FASTENERS
Asymmetric Fasteners Inc. applies new thread technology for unsurpassed locking performance.  Our patented vibration
resistant fasteners uses asymmetric threads to self-lock.  The wedging action between the shallow thread inclines of the nut
and bolt/sleeve creates a self-engaging bind as the nut encounters resistance.  

Our goal at Asymmetric Fasteners is to provide state-of-the-art fasteners that combine vibration resistance and self-locking
technology with uncomplicated installation.  By design, AFI delivers self-locking, vibration resistant nuts and bolts that do not
require additional locking components, simplifying installation and creating cost-effective solutions for fastening needs, all
without sacrificing reliability and effectiveness.

1/2/13 bolt and nut (our A-lock) were supplied to independent laboratory for the vibration test.  The steel bar (6.0” long x 1.0” wide x ½” thick) was attached
at one end to a shaker arm, and other end of the bar was free hanging.  The nut was torqued to 45 ft/lb.
The duration of the random vibration test was one hour for each X, Y and Z axis, and subjected to a frequency ranging from 20 to 2000 Hz.
The test results showed no visual anomalies noted on units.  The certification was issued per specification
MIL-STD-810D, Meth. 514.3, Proc. 1 Cat.
