has a significant advantage over traditional nuts and bolts: the shallow incline of the asymmetric thread
prevents relative motion between the bolt and nut, producing a locked, vibration resistant condition.  No
need to be concerned about tensile preloading with
A-Lock fasteners -  our vibration tests were successfully
performed with the nut tightened  below standard industry recommended torque values.
A-Lock stainless steel fasteners replace traditional nuts and bolts, eliminates additional hardware, improves
customer satisfaction and are reusable.
