Two sets of 1/2 “ diameter nuts and bolts (our A-lock) were supplied to independent Laboratory for the vibration test. One set was made from 18-8 stainless steel and one set was made from low carbon steel. The steel bar (6.0” long x 1.0” wide x ½” thick) was attached at one end to a shaker arm, end other end of the bar was free hanging (see fig.). 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 as shown in the data sheet below.
The test results showed no visual anomalies noted on units. The certification was issued per specification
