This anti shakeout fastener utilizes opposing tapered surfaces to generate radial locking force. Technicians install these paired discs on heavy machinery frames, bridge supports, hydraulic cylinders, and off road vehicles where constant motion threatens standard nuts. The design creates permanent preload without adding friction that weakens the joint. Each set functions as an exact replacement for Nord-Lock DB model 1537 wedge plates.

✅ Inside measurement sits at 17 mm (0.67 In.) for perfect bolt alignment
✅ Outside footprint runs 31 mm (1.21 In.) to spread clamping pressure evenly
✅ Total height measures 3.3 mm (0.13 In.) with tight plus minus point zero one tolerance
✅ Minimum forty six HRC surface hardness blocks deformation under pressure
✅ Ready to mount on hex cap screws and socket head fasteners straight outta box
