The VALUE COLLECTION LWDT-100USA-050BX is a No. 10 external tooth lock washer designed to prevent fastener loosening under vibration and dynamic loads. Manufactured from Grade 1075 steel with a zinc-plated finish, it features an dished profile and serrated external teeth that bite into the mating surface when torque is applied. The inside diameter measures 0.204 inches and the outside diameter measures 0.569 inches, with a thickness of 0.029 inches. This washer conforms to DIN 6797 and DIN 6798 standards. It is supplied in a minimum order quantity of 50 pieces and is suited for general mechanical assembly work across HVAC, electrical, plumbing, and industrial applications.

This external tooth lock washer is used wherever a No. 10 screw or bolt requires positive locking action in metal-to-metal assemblies. Common installation scenarios include panel mounting, equipment chassis assembly, motor mounting, electrical enclosure hardware, and light structural fastening. The zinc plating provides baseline corrosion resistance for indoor and light-duty environments. Trade professionals in HVAC, electrical, and general mechanical service will find this washer appropriate for standard equipment assembly and maintenance tasks.

Installation Notes

Install this washer between the fastener head and the mating surface with the teeth facing the material being clamped. Ensure the mating surface is clean and free of coatings that would prevent tooth engagement. Apply torque gradually and evenly to seat the teeth properly. Lock washers of this type are single-use components and should be replaced rather than reused once removed.
