Asymmetric Fasteners Inc.

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.

FASTENERS CERTIFICATION

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. 4.
